Volumes of revolution and the editing of lighting only became available in version 3.10. This is a free upgrade from v.3.04.1 and is available from your dealer.

The other features you mentioned should all be availabe in v.3.04.1 as detailed below:

> in 3D selecting a point and a line: it doesn't draw the
> closest point, contextual menu suggest only "normal
> plane".

Select a straight line and a  point and "Closest Point" should be avaliable in the right-click menu. You should not have an option for "Normal Plane" so this suggests that you perhaps don't have the correct objects selected.

> in 3D selecting two skew lines: it doesn't draw the closet
> point (contextual menu don't suggest it).
> in 3D selecting two skew lines: it doesn't calculate angle
> between (contextual menu don't suggest it).

Selecting two straight lines (and nothing else) should give the right-click option "Shortest Distance" and also "Angle between Lines".

Hope this helps.

We at Bedford School have just upgraded to version 3. I have been running a 1 user copy for a year without problems, so we decided to let everyone have a go. The 3D part does not work, saying we need  DirectX v9. We have this in place but still no joy.

The school operates a system with a few main servers where the software resides, then many terminals operating in a time-sharing mode. This means the typical user has no local processing power (it all happens at the server level). the server has a 3D graphics card, and directX v9

I am concerned that the 3D part will only work in a one-user-one-PC mode. Can anyone throw any light on this?
