Constraints for assembly explosion view? (by Daniel M.)
Hi,

I'd like to create an assembly of some parts and contrain it so that dragging any part will be between a) final position in a device, and b) in an explosion view with a maximum distance.

I've tried to add contruction lines an point-on-curve contraints, but they are not limited to the length of a line.

If this can be done, maybe the next thing on my wishlist is feasible, too: dragging one part "out" of the assembly adds the same spacing to all other parts, so that an automatic explosion view is created.

Thanks many times in advance and best regards,
Daniel

Have you looked at the tutorial on linkages, http://solvespace.com/linkage.pl?

As a related question, I have troubles understanding why I frequently run into overconstrained assemblies. In particular, I have had to learn that contraining normals usually works OK, but assigning two parallel line constraints wont -- I'd assume this would result in the same thing?

Attached is a corresponding example: contstraining the 1st part2 works, while it fails as mentioned with the 2nd time. Each time, there is also a point-on-line constraint.

Hi Andrew, yes I did, but it did not occur to me how I can create a "simple" mechanism that does the trick. Maybe you can help me with that? The example I have just posted is a good start: the final part position is when the parts are in contact.

Attached is the above example, slightly modified. The mechanism is the simplest I could think of, but it has two major flaws: it does not stop when the two parts are in contact, and pulling it too far breaks the contstraint :(

got it :) (by Daniel M.)
Ok, got it, the simplest I could think of is a circle with a horizontal line attached to it as a handle, and then constrain a point on a surface of a part to this line.
Maybe it helps someone else, I'll attach it as a simple example.
