AutoCAD Assistance Fast-Forward

Thanks for your response, Massey. I have looked at this site. My questions ( basically yes / no ) are specific to the use of AutoCAD, as a PC application.

Here's a link to the AutoCAD forum on STL files.

I only have ACAD 2007, but the Quick Reference says,

*The solid model must lie in the positive x,y,z-octant of the WCS.

*This command exports a single 3D solid; it does not export regions or any other AutoCAD object.

Have never done this, but I gathered: make sure you are working with solid objects and not surface bodies (since you are apparently new to AutoCAD, this is very important, not that I'm an expert).

To answer your questions: yes layering is applicable and very useful with 3D, although the term 'layer' is a little mis-leading. As far as the Boolean processes: imagine you have 2 intersecting cylinders, a blue one on layer blue and a red one on layer red. If you add blue to red, the result will be on layer red. If you subtract red from blue, the result will be on blue. (I'm not sure about intersection, but I'm sure it's on one layer or the other.)

The objects can be drawn/defined either way, just be sure your final solid is in the positive x,y,z octant of the World Coordinate System.

Googling "STL file AutoCAD" will point you to more useful information.

First question answered. Thanks

Re-reading, "*This command . . ." refers to the 'StlOut' command in AutoCAD (2007).
