How to Design the Complex Shapes of a Rotary Engine

Click For Summary
The discussion focuses on the design complexities of rotary engines, particularly the Wankel engine, which utilizes a triangular rotor moving within an epitrchoid housing. Participants share insights on how to accurately draw these intricate shapes using CAD software, emphasizing the importance of understanding the geometric relationships involved in the rotor's motion. Techniques for creating the rotor and housing profiles are discussed, including the use of specific ratios and incremental rotations to achieve precise designs. Several users recommend Autodesk Inventor and SolidWorks for modeling, highlighting their capabilities in generating the necessary shapes and animations. Overall, the conversation provides valuable guidance for graphics students and engineers interested in rotary engine design.

I know about 1% of Autocad's functions... and that may even be optimistic..

When a circle gets drawn on the wrong plane I usually just 3drotate it back to where it's supposed to be.. .I think it has something to do with dynamic UCS.
