Grasshopper user objects are files you can add to Grasshopper to enhance and ease your workflow. Mostly they are clustered components. They will reside with the other components, which makes them easy to use.
Everybody can create them by "File > Create User Object…"
Actually a small python script which allows the user to input a curve, curve parameters (= where to fillet) and a radius. This works like the default 'Fillet' component in Grasshopper should work (instead it will generate a new curve for every t input…).
This is an extended version of my previous Multi Fillet script/user-object. You can now also chamfer your curves at the curve parameters you specify.
See the code here.
ShatterInt shatters multiple curves at their intersections.
Deconstructs a plane and outputs the basepoint and all the main vectors. Should be used together with the Vector Display Ex (VDisEx) component.
