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

CAD Settings• CAD>Settings…• Used to Change the

look & feel of the CAD Windowo Image Qualityo Edges/Curveso Stylus Path

• Save as system setting will make current setting defaults

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

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.

Other Manipulations

• Delete Free Lines & Pointso CAD>Modification>Delete free lines and

pointso Removes geometry not associated with a

surface

• Editing Bodieso CAD>Modify CAD Entities, Edit Body Tabo Changing only the modelo Visibility, Color, Mirror, Scale

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

Updating a ModelHow do I load a new model into an

existing program?

1. Delete the existing modelCAD>View>Delete (no undo!)

2. Load the new model3. Move the new model to match the Base

AlignmentCAD>Modify CAD Entities… Transformation Tab

4. CAD Model ComparisonLinks existing features with the new modelCAD>CAD File> CAD Model Comparison…

Creating Features

CAD>Creating Features…

• Creating Entitieso Create 2D featureso Create Points

• Section Tabo Creates Edges on

Modelo Curves or 2D Features

CAD Presentation

CAD>Evaluation…• Setup

o Select a characteristico Check Display box

• Cheeseblock Buttono Adds view as a report

• Manual CAD Presentationso Setup CAD>Evaluation…o View>CAD Portrait o View>CAD Landscape
