Cutting and Embossing

• What is Meridian Tapping and How Can It Help

This exercise shows how you can use Intersect with Model to create the edges needed to make cutouts.

1. Start with an arc and use Offset to create an outer arc. Connect the arcs with lines to complete the face.

Note: If this option does not appear, open File / Preferences to the Extensions page and check Ruby Script Examples.

This creates a construction point at the center of the arc.

3. Orbit to face the front of the arc face, and use Freeform to create a shape like this.

4. Use Push/Pull on both the freeform face and the arc face so that they intersect like this:

1. Start with an arc and use Offset to create an outer arc. Connect the arcs with lines to complete the face.

4. Use Push/Pull on both the freeform face and the arc face so that they intersect like this:

5. To find the intersection edges, select the arc wall (or at least the front and back faces of it), right-click and select Intersect with Model. (You can also find this on the Edit menu.)

There are now edges where the freeform face meets the wall.

8. Embossing is similar. Use Undo to return to the step before the intersection edges were created.

9. Switch to X-Ray mode and Push/Pull the freeform body so that it stops inside the wall.

Select the freeform body and activate Rotate (Tools / Rotate). place the protractor at the construction point.

6. To see these edges better, delete the portions of the freeform body that extend past the arc wall on either side.

11. Press Ctrl/Option to make copies, and set the reference axis anywhere. Rotate-copy the original form on either side.

7. Now erase the faces inside these edges, on both sides of the arc wall. The result is a solid arc wall with a solid cutout.

12. The intersection edges are only needed on the outer face of the arc wall. Right-click on this face and select Intersect with Model.

13. Erase the overhanging portions to see the three sets of intersection edges.

14. Erase the freeform faces, and you see partial cutouts - similar to poking the bodies slightly into the wall.
