Description
This macro creates a parametric pyramid. The radiuses and the height will be set at creation time similar to Part Cone. All parameters can be adjusted. It is possible to create pyramids with a perfect tip.
How to use
- Install: See info at (github_link)
- Once installed, open Menu → Macro → Macros. Click on pyramid.py and then click on button execute.
- A knotted pyramid will appear, similar to Part Cone
- Change the parameters just like with Part Cone.
Script
pyramid.py
