Tutorial 5: Basics: Function-Blocks for Motion

Function-Blocks (FBs)

Note: MechDesigner is different to normal CAD. Parts move in MechDesigner! Motion is within MechDesigner's kernel, and not added later, as with other 'standard CAD' software.


There are two type of Function-Blocks:

Function-Blocks that specify or analyze the motion of Parts - we call these Kinematic-FBs.

Function-Blocks that we use for modeling - we call these Modeling-FBs.

In this tutorials we will learn the basic applications of the main Kinematic FBs


Note: We will show Function-Blocks that we use for Force Analysis in a later tutorial.

We add, connect, and use the Kinematic Function-Blocks, so that you can plan how and when to make kinematic-chains move.

To plot the motion-values at the output from each Function-Block, we can connect wires to the input of a Graph FB. This is not normally necessary. But, it will help communicate how the motion-values change with each Function-Block.
