CAD Programming
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
CAD Programming in 6 easy steps

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

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

Changing Orientation
• Change the Orientation of the model to match the way it will be setup on the CMMo CAD>Modification>CAD
Model Transformation…o Don’t bother with
translation

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

Healing
CAD>CAD File>Automatic Healing
• Tools to fix issues with CAD modelso Simplificationo Stitchingo Build Geometryo Correct Boundary Curves
• Healing will change your model!o It will also combine all CAD bodies into a
single body
![Page 12: Calypso CAD Functions - R L Guimont Co, Inc · Calypso CAD Functions The Basics & Beyond Jon Guimont. ... Calypso o 1 neutral format available ... §Catia, ProE, UG, Solidworks §DXF](https://reader031.vdocuments.mx/reader031/viewer/2022022011/5b1579bc7f8b9a45448c63fa/html5/thumbnails/12.jpg)
Healing
• Simplificationo 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).
• Stitchingo 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.

Healing
• Build Geometryo 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)

Healing
• Correct Boundary Curveso 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.

Loading Multiple ModelsHow 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
