I have been fiddling with Assembly constraints lately and find something I
cannot explain.... not a bug, just my limited experience probably. I have a
shaft with 1-1/4"-5 ACME screw thread, this is held by a Threaded bushing.
To be able to simulate the movement, I would need to place a rotational
constraint and a mate constraint. Turning the shaft, obviously creates a
lateral movement. I am finding the results I work out to be different to
those Inventor is returning. In the above example, I figure, turning the
handle through 360° would result in the bushing/threaded(depending on your
method of fixing) shaft moving 1/5 of a inch. This is not happening, it is
moving about 1/32 of a inch. Can someone explain what is going on.
TIA
