Is there an easy way to rotate by dragging in MLCAD?
I have a situation where I want something to be tangent to two things and
it's a complex 3 dimensional angle to calculate. I know the endpoints, more
or less.
What I would like to be able to do is this:
- Move one end of the item (part or subassembly, in this case my piece of
string, but it could also apply to straight sections of rubber bands, hoses,
etc or even parts) to the tangent point I want.
- Move the rotation point of the item to that point (temporarily)
(so far these are both doable)
- Using the top and side views, *rotate* the other end of the item into
place... that is, mouse drag to ROTATE, not to move. Any dragging rotates
the item around the rotation point I fixed, but does not move that end of
the item away from the rotation point
(I believe this is not currently doable)
- bonus style points: restore the rotation point back to the part (or
subassembly) BACK to the previous point without having to remember what it
was and type it in by hand.
(I believe this is not currently doable either)
Thanks. Suggestions of how to do it with other tools also gratefully
received. Just no matrix multiplication, please! :-)

| (...) more (...) hoses, (...) From here what you can do is calculate the angle you need, based on the difference of the endpoints and a inverse tangent funtion. Or you can calculate the angle automatically using Paul Easter's handy calculator ((URL) (...) (23 years ago, 11-Apr-02, to lugnet.cad.mlcad)
