What is the difference between Extrude and presspull command in Autocad?

 EXTRUDE ONLY WORKS WITH BOUNDARY OBJECT / PL-REC -C ../ PRESSPULL COMMAND WORK WITH ANY CLOSED OBJECT ,YOU CAN PRESSPULL A SURFACE IN3D ALSO 

The EXTRUDE command allows you to create a solid object from circles, polygons, and objects, created from or converted to Poly lines, that have "closed" paths.

The PRESSPULL command will enable you to extrude an element from any enclosed boundary between lines that are not necessarily a closed poly line This is a quick and easy way to create an extruded shape from a closed boundary.

Hi,

I never use AutoCAD as a3D tool, but I agree with Mr. Shakeel.

I'll just say that PRESSPULL works also when you want to create a surface formed by a mix of AutoCAD "primitive shapes" (lines, circles, splines, etc), unlike EXTRUDE which only works with one kind of shapes at a time (if you try to extrude with multiple types of primitives, it will extrude a planar surface, not a3D object).

I hope It was understandable, despite the redundancy of the words "surface" and "shapes"...
