Project: Basic Wireframe Geometry 2

Project: Basic Wireframe Geometry 2

Completion Time: 15 Minutes

Objective: To reproduce wireframe geometry that you will use when creating surfaces.

Process: Create points and curves on a surface using wireframe geometry features.

Instructions

1:  Open basic_wireframe_geometry2.CATPart.

2:  Create a point on the surface 60mm away from the center of the surface in the X direction.

Create a wireframe circle on the surface centered on the point with a radius of 35mm.

Step 2 Details

Create the point using On Surface as the Point type and set the direction using the pop-up menu. Activate Geometry on support when creating the circle.

3:  Create a point on the circle using a ratio of 0.25, modifying the default reference extremum point within the Point Definition dialog. Use the X direction as the extremum reference direction.

4:  Create another point on the circle directly opposite the previously created point.

Step 4 - Details

Use the previously created point as the reference point and use a ratio of 0.5.

5:  Create a line between the two points and use the surface as the support.

Step 5 - Details

Use the standard Point-Point line option, but select the surface as the support.

6:  Create a 45mm corner between the two edges of the surface.

7:  Create three equally spaced points and planes on the corner curve.

Step 7 - Details

Use the Points & Planes Repetition dialog to create the points and activate Create normal planes also to create the planes.

Review: In this project you reinforced your knowledge of wireframe geometry. Understanding the various geometry creation methods is extremely important because it is the foundation of surface creation.
