I built the assembly with both insert and mate constraints, but the final constraint that was to tie the assembly together would not take.
GEOMETRIC CONSTRAINTS AUTODESK INVENTOR PRO 2015 SERIES
The assembly is a series of linkages that don't really have a end or intermediate position that is easily defined. The difference being that The geometry of the assembly does not really lend itself to the final constraint that would disallow movement. I had done as you have suggested to some degree. Good Luck RE: Drawing Constraints wendert (Mechanical) If you are still having trouble you can send me the assembly. You can check for interference between parts if you require a set movement but are unsure if the parts are actually touching. This allows you to set the links in motion with rotational and linear limits set by you so that the parts don't move through each other. Once you find the ideal (there is always more than one solution)constraint, you can then use the "drive the constraint" tool. Inventor lets you state the angle but if the parts are closer to the 180 opposed solution it will use that. As you might see, the solution for a 10 degree angle can also be 180 degrees opposed. Inventor doesn't respect angles very well. Using the angular constraint alone to do this is risky. Sometimes its a mate or flush with offset between origin axis planes of two parts or just between two surfaces. Once all the parts are linked and allowed to rotate and slide together, you should select the best constraint the will stop the movement. Linkages generally use rotational movement and linear movement in combinations. You've used the mate contraint for axis (piston in cylinder for example). Use the insert constraint for pins and bolts in the mating parts. With any linkage, you should constrain the parts to actually allow them to move like they would in real life. I take it you want to fully constrain the assembly. RE: Drawing Constraints cadranger (Military) 3 Jun 03 08:35 Any ideas? Has anyone else experienced this issue with linkages? In dealing with linkages, the actual gemoetry will allow for 2 positions to be observed, and I wonder if this is why I am having such a time of it. I know it is not an issue of the geometry not being able to actually accomplish this because I can manually move the 2 pieces through each other while constrained axially. This worked to line up the items with respect to the axis of each item, but I still require to constrain the items to set a position of the clevis on the shaft. So, I next tried to constrain the 2 items together axially with a MATE. I have tried to constrain the model with an insert constraint, but that did not work. However, the last constraint couples the cylinder with a Rod Clevis to tie it all together.
I have a series of linkages that are coupled so that I can drive the assembly with a pneumatic cylinder. I am having difficulty with an assembly in terms of actually constraining the assembly.
