I use maplesim to construct a cart, which is controlled by a DC magnet. As the model in the document illustrated, the cart is drived by a prismatic, and there is a rigid body frame between the cart and the prismatic. This rigid body frame is used to sustain the cart. If delete the frame, wheels of the cart will descend bellow horizontal plant. This should be avoided. Is there any to to hide this sustain frame?
If I creat a subsystem, but under some purposes I want to release it, namely, make the containings of the subsystem appear in the main system and don't use cut/paste, then how can I do it?
By the way, how can I append a small picture upon the surface of a subsystem block?
