Simple because this makes the simulation faster.
Why simulate with a machine?
- It looks cool
- The kinematic for multiaxis is with current PP in the machine, not in the PP
- Collision detection is intergrated
- You can see if the part will fit in the machines WCS
Ok not really useful for a 3axies router, but if it is with a 5axis head like this:

So this is my first try for a router you can dial in the size with 3 parameters easy peasy
Not so easy was to set the constraints and joints to keep the parts in place when changing the size...
