3 Agenda The Basics o Programming from CAD Beyond o CAD Settings o Model Manipulation o Loading Multiple Models o Updating a Model o Creating Features o CAD Presentation

4 CAD Programming CAD Programming in 6 easy steps 1. Load the Model 2. Change the Orientation of the Model 3. Create the Base Alignment 4. Create Clearance Planes 5. Create Characteristics & Features 6. Run the Program

5 Main CAD Tools What happens when you click on the model o Select the corresponding feature from the feature list o Used to define a Point Feature o Create a Circle on (Cylinder or Cone) where you click o Click & Drag to define a line o If the element is in the feature list use the existing feature, otherwise create a new feature This is the go to tool

6 Loading a Model Create a new program and select CAD>CAD File>Load o Acis (*.sat, *.sab) is the native format for Calypso o 1 neutral format available STEP IGES o Direct import available as an option Catia, ProE, UG, Solidworks DXF included with Curve Option

7 Changing Orientation Change the Orientation of the model to match the way it will be setup on the CMM o CAD>Modification>CAD Model Transformation o Don t bother with translation

8 CAD Programming Use your CAD tool to define features from the CAD model Use Resources>Stylus System> Preassign stylus system for Measurement Plan autom. to automatically assign stylus for each feature in program Go back into Clearance Planes to update setting for each feature First run have to do a Manual Alignment

9 Agenda The Basics o Programming from CAD Beyond o CAD Settings o Model Manipulation o Loading Multiple Models o Updating a Model o Creating Features o CAD Presentation

10 CAD Settings CAD>Settings Used to Change the look & feel of the CAD Window o Image Quality o Edges/Curves o Stylus Path Save as system setting will make current setting defaults

11 Healing CAD>CAD File>Automatic Healing Tools to fix issues with CAD models o Simplification o Stitching o Build Geometry o Correct Boundary Curves Healing will change your model! o It will also combine all CAD bodies into a single body

12 Healing Simplification o Converts freeform surfaces (spline geometry) into their corresponding analytic forms (e.g. arc, cone, plane, etc.), wherever possible. o Be cautious of increasing the default tolerance (10μm). Stitching o Combines sets of faces to form a single sheet or solid body (e.g. 2 halves of the same cylinder). o Minimal changes to the model.

13 Healing Build Geometry o A series of geometric operations are performed to improve the precision of face, edge, and vertex data. o Essentially the model is completely rebuilt. o Includes Simplification & Stitching. o Only use if necessary (typically only IGES models)

14 Healing Correct Boundary Curves o Gaps in the boundary curves of surfaces and sections which are not exactly aligned are corrected. o Makes model watertight o On by default and should be used anytime you are healing.

15 Other Manipulations Delete Free Lines & Points o CAD>Modification>Delete free lines and points o Removes geometry not associated with a surface Editing Bodies o CAD>Modify CAD Entities, Edit Body Tab o Changing only the model o Visibility, Color, Mirror, Scale

16 Loading Multiple Models How can I have the part & fixture in the same program? 1. Load the part model 2. Load the fixture model 3. Position each model CAD>Modify CAD Entities Positioning Tab Use Rotation section to get bodies oriented Use Positioning section for rough positioning Use Translation section for fine adjustments

17 Updating a Model How do I load a new model into an existing program? 1. Delete the existing model CAD>View>Delete (no undo!) 2. Load the new model 3. Move the new model to match the Base Alignment CAD>Modify CAD Entities Transformation Tab 4. CAD Model Comparison Links existing features with the new model CAD>CAD File> CAD Model Comparison

18 Creating Features CAD>Creating Features Creating Entities o Create 2D features o Create Points Section Tab o Creates Edges on Model o Curves or 2D Features

19 CAD Presentation CAD>Evaluation Setup o o Select a characteristic Check Display box Cheeseblock Button o Adds view as a report Manual CAD Presentations o o o Setup CAD>Evaluation View>CAD Portrait View>CAD Landscape
