I created a custom square tube in Content Center based off something I found on McMaster-Carr. It's 3/4x3/4x0.65" tube. I entered all the fields (calculated the lbmass and Ix/Iy as well). However when I insert the component it's completely wrong dimension-wise. Instead of the above dimensions it inserts as a rectangle that's 1.18"Wx1.96"Hx0.114" wall with a 0.285" outer radius instead of the 0.038" radius I entered. Any idea what's going on here?
You can make a copy of the standard HSS library and modify the dimensions. This might be easier.
So if I edit the inserted tube and edit the body sketch all of the dimensions are correct, but everything is pink and the outline of the part still shows the incorrectly-sized rectangle.
I would just draw this as a standard part but I need to run a frame analysis on this part and it will only work with Content Center parts which is annoying
Any pink item means the item is not totally constrained. So, looks like you need to redo all the dimensions. The dimensions are not attached (stick) to the lines/curves.
Pink items in a sketch indicate projected geometry that has lost its reference. It appears that your entire sketch is "lost in space".
Can you post your original authored part file for this family?

How do I post the file? Do you want a screenshot of the row I added to the family table?
@bwang-tecoustics the dimensions are generated from the Content Center family row where I added the physical dimensions of the tube, they all have function markers in them.
No I meant how do I get the unauthored part file from inventor? Just make an IPT of a random length from the Content Center entry I created and upload that?
I didn't reuse any parts, I simply copied the library to my custom parts library then added a row and entered all the info manually.
After playing with the sketch it seems like the problem lies with Inventor trying to give the ID a corner radius proportional to the exterior radius but it can't. I had to delete all the dimensions and the inner loop, add the dimensions to the outer loop then use the offset command (which resulted in no radius). Then I went in and added the radius based on the STEP file I downloaded from McMaster and it worked fine. But if I ever need this tubing size again I'll have to do it all over
That's what I'm wondering as well. Yet it gave me an odd-sized tube and an all-pink sketch based off of my inputs
