Can't "place" part in assembly
I am trying to import a part into an assembly, and usually, I am prompted to identify the "placement" of the part in the assembly. I do not get this option at all when importing the part. I import the part, it just appears in the window as it does in the model, and there are no other options available. When changing the orientation of the model, the only options are "standard orientation" and "default orientation," although the model itself is able to be oriented from front, top, and back like normal. When I try to right-click on the part in the assembly to edit the placement, the icon for editing the part is not available.
Trouble shooting completed:
- Deleted everything in the model's prt file and tried to import it into an assembly. Still gave no "placement" options.
- Saved the prt file as an iges file, tried to import into an assembly, and it DID allow me to choose "placement" options.
So I think something is wrong with my prt file. Any suggestions on how to fix this?
