Problems with parts authoring.

[Paul Treble]

I have just started investigating parts authoring and have read the tutorials that are available. I have found how to enter lines, triangles, quadrilaterals in MLCAD and can see that the primitive parts (e.g. Stud.dat) are available in the \p directory. How do I find them in MLCAD as they don't show up with the other parts? I have checked the MLCAD.INI file which says that the \p directory is automatically scanned and the the line 1 = HIDE P is commented out. I am at a loss but I am sure that it must be something simple that I am missing.
