Extusion explanation (by Tobias)
Hi all,
I'm a complete noob at Precision Drawing on a computer.
I'm looking for an explanation of the different settings for extrusion, in particular the meanings of union, assemble, difference, and intersection.
Can someone please explain in simple language the differences and when you'd use each one?
The reference material does not even mention these settings and, being a 62 year old with no relevant history of technical drawing, I find the lack of detailed instructions frustrating.
I love the program though, it has filled a void I sought, missing for years in CAD.

The easy way to figure them out is to create a cube, and a cylinder taller that the cube, overlapping a corner, so that it is part inside and part outside the cube. Then you can try each one and, using the radio buttons, see what the result is. All but assembly create a single body, while assembly crates a separate body..

Thanks Andrew, I'll try that.

BTW assembly was originally the way to combine things *in an assembly* and later became an option for extrusions. I don't think it should ever be used outside an assembly group.
