ifitzpatrick Posted September 8, 2012 Share Posted September 8, 2012 Ok Ironcad dudes, I want the vanes to track the inside of the chamber as the pump rotor assembly rotates as an animation. I have tried radial distance and cam follower constraints, the inside surface is all tangentially constrained. ?Mechanism mode is mysterious and has no effect I can see. Knock yourselves out! (I have just thought of linking vane external profiles to suppressed external shape profiles - yeah but that would be cheating..)

dprodanic Posted September 8, 2012 Share Posted September 8, 2012 (edited) tangent breaks on inner circle can make the problem try this..... an idea... vanepump.mp4 Edited September 8, 2012 by dprodanic Quote Link to comment Share on other sites More sharing options...
dprodanic Posted September 8, 2012 Share Posted September 8, 2012 Mechanism mode should work too.... but only without quick sudden moves Mechanism_mode.mp4 Quote Link to comment Share on other sites More sharing options...
ifitzpatrick Posted September 8, 2012 Author Share Posted September 8, 2012 tangent breaks on inner circle can make the problem try this..... an idea... vanepump.mp4 34624[/snapback] Nice job, did I understand you made a surface inside that the tangent constraint is working against? The other thing I had not seen before is the allignment of the tangent constraint. Quote Link to comment Share on other sites More sharing options...
dprodanic Posted September 9, 2012 Share Posted September 9, 2012 (edited) Nice job, did I understand you made a surface inside that the tangent constraint is working against? 34626[/snapback] No. If you want to have tangent constraint to work for `inner circle` you need to have `clean` surface. The problem is in those tangent connection. I assume that this is a circle, so to do quickly, I have just delete those extra faces. Your `inner circle` is made of 4 arc. No matter they are tangent, 3D constraint will not work. It should but...... On a Part level, Position constraint will not see those line as smoothly connected. THIS PROBABLY SHOULD BE ADDRESSED AS BUG So if you need to have some tangent lines try to draw them by Bspline.... use your existing arcs outline as construction line help....

If you insist on your profile with 4 arcs, then one of solution would be this one... VanePump2_Ghost.mp4 -there is a `Ghost part` made from Project Constraint 3D geometry for Cam_path... note: - all parts should be the same kernel VanePump2_Ghost.ics - file is BETA2013#2 P.S. Mechanism mode works fine too... Edited September 10, 2012 by dprodanic Quote Link to comment Share on other sites More sharing options...
Jonas@Solidmakarna Posted September 10, 2012 Share Posted September 10, 2012 Thanks Dragan! Really well done! Quote Link to comment Share on other sites More sharing options...
dprodanic Posted September 10, 2012 Share Posted September 10, 2012 tnx Usually I`m just modeling arch. interiors/exteriors... so I like to play with this kind of tasks.. and of course there is always a new idea or a bug to discover tnx ifitzpatrick... give us some more Quote Link to comment Share on other sites More sharing options...
