We cannot overstate the convenience of Library Files. There is more than one reason to use them. Let me explain. Why use Library Files?

Calculate Cam Profile Coordinates for Manufacture in different file formats.

Kinematic software that compiles your design into a fast and precise structure

 You add parts and joints, and MechDesigner compiles your assembly into very efficient kinematic structures. YOU do not need to worry about the structure.

Both forward and inverse kinematics can be combined to design a robot path

This example looks like a lamp! However, it is exactly like a planar pick and place robot but with a base that can rotate. But the example shows another capability of MechDesigner.

When designing a mechanism that has tooling that is at the end of a mechanism, or robot, it is important that you can design the exact motion of the tooling itself.  This is why MechDesigner has at its core an inverse kinematics design methodology. 

Packaging machine designers are confronted with a bewildering array of technologies with which to implement motions - whether the operation be pushing, pulling, picking, folding or placing.
