Assembly, mating 4 points of interest

jordi_medellin

Hi, I am having trouble getting one of my parts (with 2 wholes) to connect onto another piece that is at an angle. When I connect one of the holes, it comes up sideways. I was told to do two, separate revolute mates, but it is still moving. Also was told to make sure they align perfectly, and so I did, but still not working out.

Thank you in advance

Could you please specify which parts you are having trouble with? I took a look at the document but was unsure of which parts to look at.

Sounds good, here it is https://cad.onshape.com/documents/8248edbfee5a39d329838679/w/5bb0bce345ae5afbefd1afc4/e/37354c60364e4228e23583d2

Thank you for that, I figured that part out, realizing I made mistakes on the exact dimensions. Now, I am having a new problem with mating the robotic arm in a "chain-link" manner for the parts to move together, and some of the parts are not moving correctly or sometimes they will not stay in place (like the parts called "Bott. str. arm servo/bearings". I am using revolute mates for most of the parts, and when I try moving that bottom link, it will stay in place. How would you recommend mating the robotic arm? Start with fixing the base? Then one at a time? Or mating some of the parts together first, then putting them into the whole arm?

Thank you
