I've been working on this assembly and everything was fine, then i added a part and from then on i could only select a few limited (usually the largest faces) or nothing at all! Any one have any idea why this could be? Very frustrating as I have a deadline due for uni very soon!
Thanks
Dominic,
My guess would be a graphics card issue. See #13 at Frequently Asked Forum Questions for more information. Unless you can select them, but they don't highlight when you hover on them. In that case see #6 at the same place.
And by the way, we can't open your Assembly without the Parts.
