Function-Blocks (FBs)

MechDesigner is different to normal CAD. Parts move in MechDesigner! Motion is within MechDesigner's kernel, and not added later to a 'standard CAD' package.

We use Function-Blocks to specify how a motion is specified for a Part.

Function-Blocks (FBs) can be divided in to two types. They are:

FBs that specify or measure the motion [and Force at Joints] of Kinematic elements [Parts and Joints] - we call these 'Kinematic-FBs'.
FBs that we use for modeling - we call these 'Modelling-FBs'.

Note: We will show the FBs that we use for Force Analysis in a later tutorial.

This Tutorial shows you how to add, connect and use the Kinematic Function-Blocks, so that you can make your kinematic-chains move.

For convenience, we will connect wires to the input-connectors of a Graph FB to help us you understand how the motion-values are changed by each Function-Block.
