Simple Mini Engine
Simple Mini Engine
(OP)
See attached JPEG, this is a simple and interesting engine that works off a bycycle pump. I am struggling to find the correct constraint that will allow the piston to move in the chamber. As you can see a simple align option does not work as the piston not only moves in and out but also rotates. This is made possible as the piston face is only 0.5mm thick.
I can get the engine to work with a pump but not in NX6. Any Ideas would be gratfully received.

RE: Simple Mini Engine
Thanks for your reply, what you have stated is logical. I have added a point to the piston face, however in the assembly it is not possible to select the point without double clicking the piston, once this is done I can select the point, however I cannot select the cylinder hole or any other part in the assembly.
Is there a way that I can see the point on the piston surface in the assembly? I have tried to ensure that all datums etc. are visable in view, however this does not seem to make any difference.
