3D SOLIDS

193 Views, 3 Replies

If you draw a rectangle in 2D, and extrude it to some height, is the object considered to be a "3D solid object"?
Once shaded, it obviously appears to be "a solid".
I will be working with a 3D solids modeling program that does 'collision checking" with other 3D solids. If the extruded rectangle is a solid object, it will save me the expense of upgrading to some other AutoCAD product for the time being. At least until we are comfortable running the 3D program. We don't want to be learning two new software's at the same time.

Help is appreciated.

If you LIST the object it should show you what it is and it should be a
solid.

Yes, it is a solid.
Use the ACISOUT command to save in a neutral file format (*.sat) for importing into the other software. (Assuming the other software won't read ACAD solids directly.)

Which begs the question, if you don't know how to do solids in AutoCAD then why bother learning now if they can be modeled in the other software?

Yes off course it is a 3D-solid when you extrude the 2d-rectangle using
extrude command you can list out all the solid model properties using list
command.
