woodman78 Posted April 15, 2011 Share Posted April 15, 2011 Hi, This is my first time playing around with constraints in dynamic blocks and I'm having some trouble. Hopefully someone can help. The attached image shows a block of a speed ramp. I have a linear parameter in the middle of the block to stretch the block. When I stretch the block I want the triangles to be evenly spaced. I have setup constraints as shown. They are all linked back to d6 but d6 is locked. How do I unlock it so that it changes and the dims update?

woodman78 Posted April 16, 2011 Author Share Posted April 16, 2011 Anyone got any ideas on this please? Quote Link to comment Share on other sites More sharing options...
SLW210 Posted April 18, 2011 Share Posted April 18, 2011 Why does d6 not unlock? Looks like every distance is locked. What is included in the stretch? If you post the file someone will give it a look, I might have time later today. Quote Link to comment Share on other sites More sharing options...
woodman78 Posted April 18, 2011 Author Share Posted April 18, 2011 Hi, I am posting the block itself and I wonder if someone can show how to set this up. I want to be able to extend the block and have the arrows remain evenly apsced at all times. Thanks. Round Top Speed Ramp.dwg Quote Link to comment Share on other sites More sharing options...
SLW210 Posted April 18, 2011 Share Posted April 18, 2011 I have combined your threads for a continuity to the question. Quote Link to comment Share on other sites More sharing options...
woodman78 Posted April 18, 2011 Author Share Posted April 18, 2011 Thanks for that. I would appreciate some help on it. I don't know how to make d6 unlock. Quote Link to comment Share on other sites More sharing options...
SLW210 Posted April 18, 2011 Share Posted April 18, 2011 I gave it a quick glance, still not sure what you want to move and stay. Looks like you may need a few constraints to lock your geometry. I will try to find some time, but we have a short work week and a full weeks work. Quote Link to comment Share on other sites More sharing options...
woodman78 Posted April 20, 2011 Author Share Posted April 20, 2011 Thanks. Sorry for the delay in getting back. I was on Civil 3D training yesterday. Great course. Anyway, I would appreciate it if you had some time to have a look at it. Basically what I was trying to do was to be able to extend the block. In doing so the curves at either end would remain exactly as they are. The hatched triangles would be spaced evenly along the straight edge regardless of the length. Hope this helps. Thanks.

SLW210 Posted April 20, 2011 Share Posted April 20, 2011 So, you need to array the triangles as you stretch? This is a busy week for me, but hopefully someone else will give it a look. If not, it may be tomorrow or Monday before I can get to it. In the mean time you should read up on constraints and linear array parameter set.
