How can I make a full-size 3D line drawing?

As far as I can see the 3D drawings are limited to 16 * 16 .PNG premade download objects.

I have not used LibreOffice, and have been very familiar with AutoCad 10 years ago.

What I have to make is no more than lines in 3D such as one could in AutoCad > 11
or so, such as line m perpendicular to line l, give me the coordinates of their intersection.

Is that possible in LibreOffice ?
