A recent issue has come to light :

When trying to launch AutoCAD 2010 as a non-admin user or any other new user whose windows profile was created after AutoCad installation you may get the following errors/warnings:

- Unable to load profile file. Some profile information saved in last session may not be restored.
or/and
- Customization file load failed. File not found: acad
or/and
- Font not found: simplex, Specify Font for FONTALT
or/and
- Missing workspace ribbons

As discussed here – http://discussion.autodesk.com/forums/message.jspa?messageID=6224260

I can confirm the following fix (as provided by Greg.Toews) works.

If the user’s registry profile is corrupt for some reason you can also just delete it and then start AutoCAD. AutoCAD will then create a default profile from scratch. (HKCU\Software\Autodesk\AutoCAD\Rnn.n\ACAD-nnnn:nnn)

It seems Autodesk Mechanical Desktop is being phased out. The latest release of Autocad Inventor Series 2009 does not contain the Autocad based 3D modelling package. If you want to install MDT it can be downloaded in its latest form from www.autodesk.com/mdt or a DVD requested.

On several of our CAD workstations using Autodesk Inventor 2009, we have noticed that they frequently seem to lock up whilst adding assembly constraints, if left alone for long enough it comes back to life eventually. We have not worked out yet if this is from any particular constraint or command but will keep it posted. Has anyone experienced this ?

We have since deleted all the Content Centre Parts from one of the models and it instantly improved, it was not a large CAD model with less than 100 fixings as a guess. If we can find the logic we will keep it posted !
