I'm guessing its a bug with the component, but I just wanted to double check here first. I downloaded a part file from McMaster Carr (maybe my first problem?), but when I went to put it into my assembly, all of its sketch dimensions are shown. Below is a screen shot of what I'm seeing:
So far I have tried:
-Turning on and off all of the sketches at the part and assembly level.
-Inserting the part into an intermediary assembly, but inserting that assembly into my final still shows the dimensions.
-Toggle instant 3d on and off.
I also downloaded a different but similar part from McMaster, but had the same display problems. This leads me to think there is a problem with the way McMaster is generating their 3d files, but out of all the models I have downloaded from them, I've never had this issue. I have had to set sketches to hidden, but never had the sketch dimensions displayed when inserted into an assembly. There are no dimensions shown in the part file either, only when inserted into an assembly. I've attached the problem part in case anybody wants to tinker with it. Thanks in advance for any suggestions, even if its just a reiteration of "take McMaster parts with a grain of salt".
