To Create Custom Cosmetic Threads
1. Create a simple part on which you want to create the thread. For example, extrude a cylinder, and then extrude a radial hole through it.
2. Create an extruded surface that goes through the solid material using a circle as its section. This surface will be the main feature of the thread.
* When you create the surface features, try to pick the minimum number of references to make a simpler UDF.
3. Create a copy feature of the extruded surface. Use the Exclude surfaces and Fill holes option and select the edges of the hole on the surface.
4. Click to create a surface trim feature. Select the thread as the Trimmed curve and the copied surface as the Trimming object.
5. Group the surface features in a UDF.
