griff701 Posted September 20, 2013 Share Posted September 20, 2013 (edited) Block A can move left and right, block B is fixed, block C can slide. What sort of constraint would enable me to keep D1 and D2 equal? I've tried everything I can think of Thank you.

KennyJ Posted September 20, 2013 Share Posted September 20, 2013 (edited) I'm not sure I fully understand, but have you tried grounding B and C to keep them fixed? also you could make a formula like D1 = D2 to make the 2 dimensions always be the same. Also you might need to look into creating adaptive parts and using drive constraints.

griff701 Posted September 20, 2013 Author Share Posted September 20, 2013 Thanks Kenny. This is my first Inventor project after moving away from Solidworks - so I'm sorry if I'm overlooking some very simple solutions (Like making d1=d2 lol) In SW I'd use a 'tab' mate - using a point on each arc at the end of each slot/cut (in B&C) , and positioning block A 'between' the points so the 2 distances were always equal. Block B can be fixed, Block C needs to move in the directions of the blue arrows, and d1 & d2 should always be equal. Thanks a lot Quote Link to comment Share on other sites More sharing options...

As the RHS pieces move laterally, I'd like the 'brick' to have an equal amount of 'slot' on either side. Thanks for your time. (Edit: I tried editing my original post to clarify things, and its now disappeared ! ) Edited September 21, 2013 by griff701 Quote Link to comment Share on other sites More sharing options...
