Link/Append Problems

I linked a mesh to another file, but insted of the added mesh being outlined in pink in object mode, it’s outlined in blue and you can’t do anything to it!!! Help???

If you linked that mesh from another file , you CAN’T change it because this is the definition of linking , which imported data is read-only and would change only from original file for preventing accidental change. If you want to edit imported Mesh you MUST Append it.

That’s right, but otherwise, if you’ve linked a mesh from another file, you could make a proxy with Ctrl-Alt-P, so you can change some of its properties.
