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


5/19

Main CAD Tools

What happens when you clickon the model

o Select the correspondingfeature from the feature list

o Used to define a Point Feature

o Create a Circle on (Cylinder orCone) where you click

o Click & Drag to define a line

o If the element is in the featurelist use the existing feature,otherwise create a new feature

This is the go to tool


6/19

Loading a Model

Create a new program and selectCAD>CAD File>Load

o Acis (*.sat, *.sab) is the native format forCalypso

o 1 neutral format available

STEP

IGES

o Direct import available as an option

Catia, ProE, UG, Solidworks

DXF included with Curve Option


7/19

Changing Orientation

Change the Orientation of themodel to match the way itwill be setup on the CMM

o CAD>Modification>CADModel Transformation

o Dont bother withtranslation


8/19

CAD Programming

Use your CAD tool to define featuresfrom the CAD model

Use Resources>Stylus System>

Preassign stylus system forMeasurement Plan autom. toautomatically assign stylus for eachfeature in program

Go back into Clearance Planes toupdate setting for each feature

First run have to do a Manual Alignment

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


12/19

Healing

Simplification

o Converts freeform surfaces (splinegeometry) into their corresponding analyticforms (e.g. arc, cone, plane, etc.),wherever possible.

o Be cautious of increasing the defaulttolerance (10m).

Stitchingo Combines sets of faces to form a single

sheet or solid body (e.g. 2 halves of thesame cylinder).

o Minimal changes to the model.


13/19

Healing

Build Geometry

o A series of geometric operations areperformed 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 IGESmodels)


14/19

Healing

Correct Boundary Curves

o Gaps in the boundary curves of surfacesand sections which are not exactly alignedare corrected.

o Makes model watertight

o On by default and should be used anytimeyou are healing.


15/19

Other Manipulations

Delete Free Lines & Points

o CAD>Modification>Delete free lines andpoints

o Removes geometry not associated with asurface

Editing Bodies

o CAD>Modify CAD Entities, Edit Body Tabo Changing only the model

o Visibility, Color, Mirror, Scale


16/19

Loading Multiple Models

How can I have the part & fixture in thesame 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


17/19

Updating a Model

How do I load a new model into anexisting program?

1. Delete the existing model

CAD>View>Delete (no undo!)2. Load the new model

3. Move the new model to match the BaseAlignment

CAD>Modify CAD Entities Transformation Tab

4. CAD Model Comparison

Links existing features with the new model

CAD>CAD File> CAD Model Comparison


18/19

Creating Features

CAD>Creating Features

Creating Entities

o Create 2D featureso Create Points

Section Tab

o Creates Edges onModel

o Curves or 2D Features


19/19

CAD Presentation

CAD>Evaluation

Setup

o Select a characteristic

o Check Display box

Cheeseblock Button

o Adds view as a report

Manual CAD Presentations

o Setup CAD>Evaluation

o View>CAD Portrait

o View>CAD Landscape
