how to set part material and get inertial matrix

Post by benxin4 »

hello, I’am freshman from solidworks to freecad, I love freecad, it very helpful.

Now, i meet some questions, i have a robot cad model, i want set the link material then get the inertial matrix and mass of the link.

Macro-info can give me some information, but how to get the inertial matrix of the link in different frame, such as center of mass, and drawing frame. It will very convenient for me to calculate dynamics if I know the inertial matrix and the position/posture of the link frame.
