Using grasshopper to design simple 2d mechanisms

This is possible with Kangaroo, but it’s not as user friendly as in mechanical CAD software where you can define proper constraints.

A complex linkage without collision:

This topic contains some simple examples:

Kangaroo linkages - Grasshopper / GH for Mac - McNeel Forum

In many situations you can solve the collisions in 2D which allows you to use just a curve collision goal instead of true solid collisions, which will be much faster…

Gear simulation - Grasshopper / Kangaroo - McNeel Forum

Rigid curve collide with offset - Grasshopper / Kangaroo - McNeel Forum

Have you used the search function yet?

Look for Kangaroo and curve collide / collision
