Feature request: Skip recompute of non-visible parts or bodies

[TomB19]

I use spreadsheets to create parameterized models, exclusively. It sounds like this is an expected usage model.

Often, the description of a problem is contained in a spreadsheet that spawns multiple parts.

For example:

I have a design for a foot for a vintage turntable. This foot file contains four parts. All parts are modelled from the same 20, or so, parameters.

- foot body (Main part made out of PETG)
- bellows (it's a suspension foot with a spring so it has a soft bellows made of TPU)
- pad (soft pad so as to not mar the stand surface made of TPU)
- centering washer (small washer made of PLA)

The parts are all related. If I increase the OD of the foot, the bellows needs to adapt and the pad also changes. If I change the diameter of the fastener that holds it to the table, the washer and bellows will adapt.

It works great and is a great way to organize a very small number of related parts. The problem is, even a tiny project like a turntable foot causes my machine to grind to a halt, each time anything changes, even if it doesn't affect other parts.

It would be helpful to be able to turn off recompute for non-visible bodies.
