Marcus Bertilsson Posted May 30, 2006 Share Posted May 30, 2006 Is it possible somehow to lock two endpoint positions of a part to other objects, a extruded or sweeped shape maybe? So if I move the other object the first part will be stretched with it (end point move) getting longer or shorter. Why I´m asking is because I try to model a lattice steel structure where the corner angle beam is angled in two directions and then I have to model up the side cross arms that also is as angle beam. It would be great to be able to let this cross arms follow with when I move the corner beams. It is not the lenght of the cross arms that are steering the design, it is the corner beams and the distance where the crossarms are connected to the corner beams. Length of cross arm is then only a output for cut list. Help is much appreciated! / Marcus Quote Link to comment Share on other sites More sharing options...
Cary OConnor Posted May 30, 2006 Share Posted May 30, 2006 Let me make sure I understand....You want the geometry to stretch when one of the parts it aligns with moves or do you want the part to act like a pin connection? Cary Quote Link to comment Share on other sites More sharing options...

Marcus Bertilsson Posted May 30, 2006 Author Share Posted May 30, 2006 Yes! That is pretty much it. How did you do that? Imagine that the shape in your example is a angle beam (L-beam) instead, thats my case. / Marcus Quote Link to comment Share on other sites More sharing options...
Cary OConnor Posted May 30, 2006 Share Posted May 30, 2006 Well I created it using Projected Constraints as Construction geometry then used the constraints to reference it. I'll see if I can upload an example tomorrow if I get a chance. Basically I projected the blocks as construction geometry using the right-click project to make them constrained. Then it is a matter of constraining the profile to the construction geometry. So when you move the parts, the projected construction moves then the constraints follow the projected geometry.

Marcus Bertilsson Posted May 31, 2006 Author Share Posted May 31, 2006 So is it only working on 2D sketches? Is it not possible to fix start and endpoint of an extrusion or sweep? Or is it then possible to let the 2D-shape steer the "beam"? / Marcus Quote Link to comment Share on other sites More sharing options...
Cary OConnor Posted May 31, 2006 Share Posted May 31, 2006 It works on the profile level of the geometry. I just used a 2D Profile for an example...it could have been any solid shape that the 2D profile is in that orientation. So no you cannot hook the start and end point of an extrusion.
