Constraints

[mattador04]

I need help constraining the geometry sown. If the pieces of metal were at 90, i could use a mate with an offset distance....

BUT in this case, things are weird. PLEASE HELP

You can constrain them at an angle. Question though. How would you constrain them in reality? And do they stay at a fixed angle or move?

[mattador04]

Weld. Cannot constrain at an angle because as the two assemblies slide against one another at the miter, they remain at the same angle to one another.

[mattador04]

Sorry, fixed to answer your question. It is a horizontal band on a building that is taking a corner

If its a metal part I would just define the sheet metal in an .ipt and they wont move. If I understand you they are parts in an assembly?

[mattador04]

Yes, it is an assembly (.iam) file, and yes, I have made sheet metal .ipt's that are placed in the IAM.

Even if they are sliding you should be able to constrain at an angle. Ill have to try and do a test to see. If you need the motion between them you can apply a joint and tell it exactly which degrees of freedom it has. For the angle between faces you can then dictate what angle range(same min and max) between the faces. Its easier in reality if there is a face or something that it can coincide with but you can fake it with DoF and angle limits. Anything else special about the motion between them for when i get a chance to test it out?

mattador, i got a chance to play around with this and you can use the Constraint like i mentioned. You can add whatever other constraints or joints you need and then use the Angle Type to keep them at a certain angle. Let me know if that isn't the case for you. It doesn't keep the parts from sliding along their miter joints.
