Introduction to Verisurf X

Overview

Verisurf Software is pleased to introduce Verisurf X, the latest version of our flagship software product, which builds on 15 years experience in developing leading-edge solutions for Measurement, Inspection, Tool-building and Reverse-engineering.

Verisurf X, which is based on Mastercam X3, features improvements in all areas relative to our previous products. The Measure function now handles very large point-clouds, providing support for the ever-growing use of high-density scanners. Measured data is presented in a well organized tree structure, and the Report Manager has been expanded to provide multiple reports in a single job. Analysis has been enhanced with dramatically improved performance, allowing users to analyze large scans in a fraction of the time required by previous versions. Graphical reporting of analysis results has been improved through the use of more reporting options, including the ability to save multiple analyses in a single job. Analysis also now

includes real-time surface scans, which provide instant feedback for tolerance assessment. The suite of Reverse-engineering tools has been greatly expanded to provide support for surface meshes, including very large STL files. Meshing, cropping, editing and slicing tools make it possible to create complex surfaces from point-clouds quickly and with little user input. Meshes can be used in lieu of surfaces for analysis and tool-building. Model-based Definition (MBD) has been enhanced to provide more tools and greater support for complex callouts. In addition, the MBD is always `live', and can be viewed on-screen during all Verisurf operations such as measurement, analysis, tool-building and reverseengineering. The following sections describe the functionality of Verisurf X in the new Mastercam X3 environment. For those of you familiar with the Verisurf 9.1 family of products, parallels are drawn between the old and new interfaces, to help in the transition.

Entity Selection

This exercise is to familiarize the user with Verisurf X selection methods of geometry. In using Verisurf V9 we used the selection menu: In Verisurf X the new interface has new controls to accomplish the same tasks. For those users of V9 migrating to X I suggest going over all the new methods because of the frequent entity selection usage. Of particular note I recommend looking at the QM (Quick Masks) toolbar. For those users new to the Verisurf X interface will begin their learning curve today. Entity selection is a basic skill that will be used though out this tutorial. The initial exercises to follow will give step-by-step instruction initially for entity selection and gradually taper off. (Note: The following is from Mastercams Help menu or Getting Started Guide) Mastercam's selection mode is always active when you are not using a function such as creating geometry or analyzing an entity. The following are guidelines for selecting entities:

Single entities guidelines

· Click an existing entity to select or deselect it. When selected, an entity is highlighted.

Multiple entities guidelines

· To select multiple entities using the Single selection method, single click all the entities you want to select. Notice that selected entities are highlighted and remain highlighted, indicating selection. To deselect any one of the entities you have selected with this method, click it again. To select multiple entities using the Window selection method, click an area of the graphics window that is not directly on an entity, hold down the mouse button, and start to drag the mouse to anchor the first point. Then release the button and continue to draw a rectangular window around the entities you want to select. Click to set the final position. Mastercam selects all entities completely contained within the window.

To select multiple entities using the Polygon selection method, choose Polygon from the Selection Methods drop-down list and click anywhere in the graphics window. This location will be the start point of the polygon. Continue by clicking points to create your desired shape. Close the polygon by double-clicking the last point or pressing the Enter key. To select entities using the Chain selection method, hold down the Shift key and select a single entity that is part of a chain of other entities. Alternatively, you can choose Chain from the Selection Methods drop-down list and click an entity that is connected to other entities. For example, holding down the Shift key and clicking one side of a rectangle selects all four sides and clicking one line that is connected to another selects both lines. To select entities using the Partial Chain selection method, hold down the Shift key and select a single entity that is part of a chain of other entities. This first selection also specifies the chaining direction, so be careful where you click. Keeping the Shift key down, select the last entity in the chain. To unselect currently selected entities, while at the same time selecting all unselected entities, click the Invert Selection button in the General Selection ribbon bar.

Note: Left-click a selection method to choose it for a single selection event. Right-click a method to lock it for multiple selections. Note: To finalize multiple-entity selections, press Enter, or click the End Selection button in the ribbon bar. Note, however, that you can end a series of selections by double-clicking the last entity of the selection. For example, to select three lines using the single selection method, click the first two lines. Then double-click the third line to end the selection process. (The double-click method does not work with polygon and vector selections, which instead use the double-click to complete the polygon or vector.)

All entities guidelines

· Choose the All button to open the Select All dialog box and click the All Entities bar at the top of the dialog. The dialog box closes, and Mastercam selects all entities. Use Quick Masks to control the masking-selection mode with a single mouse click.

Quick Masks

Mastercam's Quick Masks are time-saving functions that allow you to select entities by type with a single mouse click, without having to open the All or Only dialog boxes.

Figure 3-10: Quick Masks Toolbars

By default, the Quick Masks toolbar is docked vertically, directly below the MRU toolbar along the rightmost edge of the Mastercam window. Quick Masks (QM) functions support different right­click and left­click actions. · · Left­clicking sets masking to select all entities of the specified type. Right­clicking sets masking for a single selection. For example, suppose you have a rectangle that comprises four lines. If you left­click the QM Lines function, Mastercam selects all four of the rectangle's lines. If you right­click the function, you can select lines (and only lines) one by one. QM functions include Points, Lines, Arcs, Splines, Surfaces, Solids, Drafting, Wireframe, Surface Curves, Color, Level, Xform Group, and Xform Results. Use the General Selection category in Settings, Customize to add QM functions to toolbars. You can also set up keyboard shortcuts for QM functions by choosing the General Selection category in Settings, Key Mapping.

Entity Selection (Advanced)

When creating geometry, you can use several selection methods to select positions and other entities in the graphics window, including: · · · Clicking with the left mouse button to choose one or more entities, usually at the prompting of a function. Choosing General Selection ribbon bar options. Chaining (page 23).

Using the General Selection Ribbon Bar

The General Selection ribbon bar operates in two different modes Standard Selection and Solid Selection. The availability of either mode is based on the types of entities that are in the current file and the functions you choose from Mastercam menus and toolbars. If you choose a Mastercam function specific to a solid entity, the General Selection ribbon bar automatically switches to the Solid Selection mode.

Figure 3-7: General Selection Solid Selection mode

If there are no solids in your file, the Solid Selection mode is not available; you can use only Standard Selection options.

Figure 3-8: General Selection Standard Selection mode

If the General Selection ribbon bar is available for use when no other function is active, you can select entities prior to choosing a function by using the cursor or combinations of the cursor and keystrokes, such as [Shift+Click]. Then choose a function to apply to the selected entities. Some functions work in conjunction with the General Selection ribbon bar. In these functions, the General Selection ribbon bar becomes active when you are prompted to select entities for the function.

General Selection Methods

Use the General Selection method drop-down list to set the method by which you select entities in the graphics window. Selecting a method option limits selection to that method. You can left­click a method to choose it for a single selection event, or right­click a method to lock it for multiple selections. Once you have chosen one of the following selection methods, you can return to the standard selection method by clicking the Standard Selection button. To finalize multiple-entity selections, you can press [Enter], or click the End Selection button in the ribbon bar. Note, however, that you can end a series of selections by double clicking the last entity of the selection. For example, to select three lines using the single selection method, click the first two lines. Then double-click the third line to end the selection process. (The doubleclick method does not work with polygon and vector selections, which instead use the double-click to complete the polygon or vector.) From the General Selection ribbon bar, choose one of the following Selection methods to lock the method in place and disable the others. Chain: Select/chain entities that are connected to other entities. For example, clicking one side of a rectangle selects all four sides, and clicking one line that is connected to another selects both lines. *Window: Select entities by drawing a window around them. *Polygon: Select entities by drawing a polygon around the entities. Double­click to complete the polygon. Single: Select individual entities by clicking them with the mouse. Area: Select multiple nested shapes with a single mouse click. Vector: Select multiple entities by drawing a vector line through them. All entities the vector intersects are selected. *The Window and Polygon selection methods are controlled by the choices you make in the Entity selection settings drop-down list.

Masking

A selection mask is a defined set of criteria you use to quickly select entities in the graphics window. Using a selection mask with a complex part file ensures that you select only and all of the specific entities you want. When working with selection masks, you can: · · · · · Define a selection mask to use once and discard (default). Make the selection mask active until you turn it off or exit the Mastercam session. Save the selection mask criteria to a file (.MASK) that you can later open and reuse. Open an existing selection mask file and apply it. Use left­ and right­click Quick Masks to select all or only specific entity type. To use a mask for selection, click the All or Only buttons in the General Selection ribbon bar. · Choosing All opens the Select All dialog box. Use this dialog box to define and apply a mask that automatically selects all entities in the current file that match the mask criteria. You can choose to apply the criteria and select all entities, or only entities in a specified group, including groups created by Xform functions. Choosing Only opens the Select Only dialog box. Use this dialog box to set restrictions on the entities that are available for selection in the graphics window. When you apply the Only mask, you use other General Selection methods to select only those entities that match the mask criteria you define. Until you clear the mask, you are restricted from selecting entities that are excluded by the mask.

Chaining

Chaining is the process of selecting and linking pieces of geometry so that they form the foundation of a toolpath, surface, or solid. This fundamental Mastercam concept has important applications in both design and machining functions. When you chain geometry, you select one or more sets of curves (lines, arcs, and splines) that have adjoining endpoints. Chaining differs from other selection methods because it associates order and direction to the selected curves. Chaining order and direction affect the way Mastercam generates surfaces, solids, and toolpaths. When chaining is required for a selected function, Mastercam displays the Chaining dialog box. If the current part file contains wireframe and solid entities, you can use the buttons at the top of the dialog box to choose the type of entities you want to chain. Otherwise, the entity type is pre-selected.

Chaining Wireframe Geometry

Chaining wireframe entities is similar to using the standard mode in General Selection. The entities you select when chaining appear in the selection color. Use options in the Chaining dialog box to choose: · Geometry plane: You can chain entities only in 3D or the current construction plane (Cplane). Chaining in 3D allows the chain to span planes. Cplane chaining is two-dimensional; all entities must lie in a single plane. Selection method: Like General selection, chain selection methods include chained entities, single entity, window, polygon, and vector selection. You can also chain a series of non-adjacent points (useful in spline and surface creation) and create partial or open chains consisting of all adjacent entities between a start point and an end point. The Window and Polygon methods allow you to control whether entities are selected inside or outside of the selection area. Use the following functions in the Chaining dialog box to change or correct chains as you create them.

Last: Reselect the last chain of entities you created. For example, choose this option when correcting chains for a surface that did not generate properly. Mastercam rechains the entities so that you can edit the chains and correct chaining direction or order without having to manually rechain all the entities. Unselect: Unselect all selected entities. End Chain: End a chain but remain in the chaining function. You can also end the chain when defining partial chains or branch points by typing the keyboard shortcut [E]. Reverse: Reverse the chain direction. Start / End of chain: Use these buttons in the Start and End fields to move the start or end of the chain from one entity endpoint to another. Note: You can move the chain Start position only on open chains. The option to move the chain End position is available only for open and partial chains. Dynamic move start/end of chain: Change the start or end points dynamically by using the cursor to move them.

Working with Levels

A Mastercam file can contain separate levels for wireframe, surfaces, drafting entities, and toolpaths. By organizing your files into levels, you control the areas of the drawing you want to be visible at any time and the entities you can select. This control makes it easier to work with the file, and helps prevent you from affecting areas of the drawing you do not want to change. You can name levels and organize multiple levels into Level Sets, which you can hide or display as a group. In this section, you will learn about: · · Setting the Main Level Using the Level Manager Right­Click Menu

Setting the Main Level

In Mastercam, you can create and name up to 2 billion levels and set any one to be the main level. For each level you create, you assign a unique number and, optionally, a name. The main level is the current working level. Any geometry that you create is always placed on the main level. There can be only one main level at a time, but you can change the main level as often as necessary to work with the part.

Working in 2D and 3D Mode

When creating geometry, use the 2D / 3D Status bar toggle button to set the drawing mode. The default setting is 3D. Click this button to switch between drawing modes. · In 2D mode, all geometry is created parallel to the current Cplane and, unless specified, at the current Z-depth setting. You can override the Z-depth setting by typing coordinate values that include a Z-depth value different from the current Z-depth setting. In 3D mode, the X, Y, and Z coordinates are all read from AutoCursor when sketching dynamically. The Z-depth setting in the Status bar is not used. When working in a 3D environment, you can create entities whose points lie in different planes, or create entities (such as arcs or 2D splines) in planes other than the predefined planes. In both modes, use AutoCursor or the selected function ribbon bar or dialog box fields to enter coordinate values. Some exceptions to this apply to specific entity types.

Views, planes, and coordinate systems

Mastercam uses a 3D Cartesian coordinate system to locate your work in three-dimensional space. This means that geometry and toolpath positions are expressed in terms of three coordinate axes--X, Y, and Z. Each axis is signed, which means that it has a positive and a negative direction.

Because actual machining jobs often require you to work with coordinate locations in sophisticated ways, Mastercam includes several useful tools which let you transform, overlay, slice, and otherwise manipulate the coordinate system so that you can draw and measure your part in ways that make sense to you. The main tool for applying coordinate systems in Mastercam is the view. A view consists of two main parts:

· ·

A plane, or slice through the coordinate system An origin, or zero point Views also have names, so they can be saved with the part and selected at a later time. Every Mastercam part includes by default seven views. These correspond to the six faces of a cube (Top, Front, Back, Right, Left, Bottom) and an Isometric view. In addition, you can create your own views, name them, and save them. Some of the most important applications of views include:

· ·

The graphics view (Gview). This defines the perspective from which you are looking at the part in the graphics window. The construction plane (Cplane). This is the plane in which new geometry is created. You choose one of these functions, then select a view to apply to it. For example, to look at your part from the right side, choose the Gview function, and then select the Right view. To draw geometry on the back of your part, choose the Cplane function and select the Back view.

Build 8-12-2008 (Beta 1)

0BIntroduction to Verisurf X · 39

Because Mastercam breaks these out into separate functions, you can maintain the plane selections for each function independently. For example, you can be looking at the part in isometric view (Gview = Isometric), while drawing geometry on the front of the part (Cplane = Front). The default plane, Top, corresponds to the standard XY plane for simple 2D geometry.

·

·

Choose Gview on the status bar to orient the graphics view. You can also use the menus at the top of the screen: select Views, Standard or Views, Orient. Choose Planes on the status bar to set construction planes.

Work coordinate systems

Mastercam also lets you shift and move the coordinate axes themselves. This lets you create a work coordinate system (WCS), which lets you move the coordinate system to your part geometry instead of moving or transforming the part geometry. Think of the WCS view as defining the "shop floor" relative to your part. For example, an aerospace part might be drawn and dimensioned to the tip of the nose or wing. You can use the WCS to align the coordinate axes and origin with the part before creating the toolpath. Then, when you post the toolpath, the NC code will look like the part is flat so you can machine it simply. Or, you can create different WCS's for different part fixtures and assign work offsets to each one, so that when you post the toolpaths each will start at the zero point with the proper work offset code included automatically. Gviews, Cplanes, and Tplanes are all measured relative to the WCS and its origin. However, you change the WCS in exactly the same way that you change those functions: create a view which captures the orientation and origin that you desire, then set the WCS equal to it. Choose WCS on the status bar to realign or create a new work coordinate system. This menu is also the standard way to access the View Manager, which is a central location for editing, renaming, and managing views.

Screen Statistics

Displays summary information on the entities in the current file, including the total number of visible entities by type, and the number of operations and tools. Example:

Shading surfaces and solids

Applying shading to surfaces and solids in the graphics window for the current drawing session helps you visualize 3D geometry while you work. You can also use this feature to provide temporary shading of entities, which you can then save as a bitmap file or print for future use. Use the Shading toolbar (shown below) to choose different shading display options.

Shading parameters--e.g., color, materials, lighting--can be set through the Shading property page (System Configuration) and the Shading Settings dialog box. Notes:

· · · ·

You can quickly toggle shading on and off by pressing [Alt+S]. Shading does not provide a permanent, savable image. Shaded images update to reflect the changes you make to the geometry. Existing parameter settings are maintained and, until changed, used whenever shading is turned on.

Complex geometry will take some time to shade. In cases such as these, Mastercam will not display the geometry being shaded. Instead, you will see a progress indicator within the status bar that will provide feedback that the shading process is still running. Upon completion of the process, your geometry will appear shaded.

Using the Analyze function

Use the Analyze function to view entity properties and edit some or all of the data, based on the entity type. To analyze entities, use general selection methods and select one or more entities before or after choosing the Analyze function. You can analyze all entity types, including:

· · ·

Lines, arcs, points, and splines (parametric and NURBS) All surfaces and solids Drafting dimensions

Final Introduction Exercise

This exercise will involve opening an IGES file that has all entities on Level 1 and all the same color. You will then use the skills acquired in the preceding sections to move the various entities to named levels and color the entities to specified colors. 1. Open the IGES file VERISURF Intro test.IGS using skills learned from OPENING A FILE on page 11. 2. Use the level manager to verify that it reads as follows:

3. Using the Analyze button to see that then entities are Color 152. Using the skills from ENTITY SELECTION and COLOR CHANGE we will now separate the various entities by COLOR. 4. Select all the surfaces. This can be done with a few different methods. Individually picking them, using the QM(Quick MASK), the Ribbon bar with a masked window, etc. Your method used will develop as you gain proficiency. 5. Once all surfaces are selected use the Color in the STATUS BAR to change them all to BLUE-9 6. Using the same skills change the COLOR of all splines to CYAN-11. 7. Using the same skills change the COLOR of all arcs to GREEN-10.
