Why is my assembly overdefined?
Sorry I'm still a beginner, but I cant seem to understand what joint is over defining my assembly. I just want to pull the finger down by pulling a solenoid back, but when i put the final revolute joint, it all breaks. If i suppress the slider joint and freely move it, then its perfectly capable of doing the motion I want,…

Mates - How to prevent the last link from moving relative to the previous one?
Hi everyone, I've created a manipulator model in Onshape using revolute mates (from left: column- fixed, link1, link2, link3 - all revolute). I want to make sure that the last link (link3) does not move relative to the previous one (link2) when I move the first link (link1) . How can I achieve this? Before moving first…

Replicate breaking mates
Hey, So I've built some assemblies and they work fine. The parts have zero freedom in the assembly and are all located as I want them to. Then I put that assembly into a higher assembly and it works, it looks great, everything in the initial instance is in the right place but then I replicate it and the replications have…

Confusion about mates, groups and assemblies
I have an assembly, call it ASSEMBLY1. I want to it attach to a revolute mate in another assembly, Call it ASSEMBLY_MAIN. I group the parts together in ASSEMBLY1 and create a mate at the pivot point. I insert ASSEMBLY1 into ASSEMBLY_MAIN and create a revolute mate with pivots. When I run the animation, ASSEMBLY1's group…

assembly pattern breaks original mates.
If I pattern a mated part, the original mates fail. how come.? anyone else experienced the same thing? simplified example: Untitled document | table (onshape.com)

Exporting assemblies with mate data intact
TL;DR: I want to export an assembly so that I can import it to an animation program while retaining mates This at first seems like a silly question to be asking. A few months ago I was working on a project that involved analyzing an assembly I made with OnShape in MATLab's Simulink program. As I was learning to use the…

Subassembly non-fastened mates not working in higher assembly
I have a subassembly with a revolute mate which has limits of +/- 45deg defined (see animated gif). When this is inserted in a higher level assembly, all of the limits are no longer viable and everything acts like a fastened mate in whatever the last position was when the version was created. Is this expected behavior?…

Can I have unique names for assemblies and their mates that are created via circular pattern.
Hi, I've got a couple of subassemblies stacked and connected via revolute mates into a "tower". I have no problem duplicating this aggregate assembly using Assembly Circular Pattern, resulting in a few towers. However, I've got the mates uniquely named in tower1 (dof_tower1_a, dof_tower1_b, ...), and would like to be able…

Two tangent mates
Has anyone ever managed to have one part mate tangentially in two positions? I have a plate with rollers moving along two tracks from one position to another and this should work, but Onshape thinks that i am over defining the assembly, which i am not. If i remove one of the tangent propagation options on either mate, it…

Finding mate features that relate to an assembly
Is there a way to easily find those mate features that relate to an assembly. I would like to click on an assembly and the related mates be highlighted in the mate features tree, bottom left. The only way i can find those mates is be trawling through all the mates by running my mouse over them to see which is the closest…

How to mate a cross beam to slide loose / loosely in a cross slot
I'm trying to figure out how to mate a cross beam (a long beam with a cross section of a cross, plus sign, etc...) so it accurately slides in a slightly larger cross cut in a plate. The goal is something that can move up and down, tilt slightly to the left, right, forward and back, but not rotate (although in reality it…

Is there an easier way to mate this shelf assembly?
I have just modelled a shelf assembly in sheet metal, everything went well apart from mating the legs to the shelf. If someone could look at the attached model and tell me of an easier way to do this I would be grateful. Regards, Derek…
