Why can’t I offset a polyline in AutoCAD?
If you (sorry, AutoCAD) can not offset polyline – please check at first that this polyline doesn’t have zero-length segments, i.e. each vertex pair connected with non-zero length segment.
What is intersection in CAD?
With INTERSECT, you can create a 3D solid from the common volume of two or more existing 3D solids, surfaces, or regions. If you select a mesh, you can convert it to a solid or surface before completing the operation. You can extrude 2D profiles and then intersect them to create a complex model efficiently.

What is sweep command in AutoCAD?
The 2D sub-object or object is swept along an open or closed path to create a 3D surface or solid using sweep command. The object enclosing the area is swept to create a 3D solid or surface, but an open-ended object is swept to create only a 3D surface.
What is the use of offset tool?
Use the Offset tool to create a new feature by offsetting either a surface or a curve with a constant or variable distance. You can then use offset surfaces to build up geometry or to create patterned geometry, or you can use offset curves to build up a set of curves that you can then use to build a surface.
