Hello,
Try the following. Add a simple hole wizard hole in a part i.e. 1/2" UNC. Now make an assembly with this part and create a drawing of the assembly. The thread will show up as a bored hole only. If you create a drawing of the part itself, the thread is displayed properly. That was the case in SW 2006 SP 5.1 and is still the case in SW 2008 SP 2.1 on my machine. Can anyone verify this? Maybe with SW 08 SP 3.1
Thanks,
E.
