Pattern FB

See Add Pattern FB

If you use regular CAD, you will know about circular and linear arrays. In MechDesigner, there is more complexity because parts have complex motions.

A Pattern FB makes Copies of Profile/Extrusions and CAD-Solids - see Solids,

The Pattern FB anticipates the motion of each Copy and puts each Copy at a different phase of the machine-cycle.

The Pattern FB can show or hide each Copy for the machine-cycle.

The Pattern FB can show or hide each Copy as it passes through different phases of the machine-cycle.

Use Visibility toolbar > Show Solids in Mechanisms to see the Copies of the Solids that are generated by the Pattern FB.

Phase Visibilities

To help you understand what the Phase-Visibilities can do, it is helpful to think of a chain around a circular 12-hour clock. The chain moves continuously around the clock. One of the chain-links is the Source Pattern-Element (Solid).

Use PHASES to decide how many chain-links you want in the chain - called # Copies

Use PHASES to hide one or more chain-links (the Copies) permanently, all the way around the clock.

Use Pattern Visibility to hide chain-links (one link after the next link) only as they move between hours e.g.: 6 and 9 o'clock
