I'm  having a 2D house plan drawing layout and I need it extruding 4.* meters in elevation. I need to convert them into 3d. But they are regular lines, so I'm looking for away to turn them in to poly lines, or should I have to manually re-draw them as plines?

You can use PEDIT to convert Lines to Polylines. Plus you can extrude the polylines to 3D.

You could just as easily use the PressPull command depending on the version of AutoCAD you are running.  PressPull will work on lines, arcs, polylines and splines.  Another option is to use the Polysolid command to draw any new walls.

1] since you posted in Map/Civil forum, you'd better _MAPCLEAN your layout, in order to join automatically those lines into closed polylines.
Then you could offset them to get walls, extrude all, finally subtract the inner solid from the outer one.2] if you cannot handle the 3D environment, here's the simplest way to "see" your layout: select your actual linework, then _PROPERTIES and edit the THICKNESS field.This is a "2.5" drawing, not really solid, but very quick to accomplish...

I would recommend against using thickness as it may come back to haunt you later on if you want to start creating openings in your structure for things like doors and windows.Another word of caution, if you extrude a line the result is a surface.  Since you're constructing a house I'd say stick to creating/using solids not surfaces.John Connor2012-11-20 13:55:22

As I wrote, this simple technique is fast and useful to see a draft version of the project, without knowing what's the 3D space.Another nice way to force Map to work in architectural fashion, is to create a topology network from the linework, then buffer it to make wall sections to extrude.

No, the simple technique is to use PressPull and the user will get a solid which is just as fast.Anyways, we don't know if the user posted in the wrong forum or if he was using an AutoCAD vertical product but switched to the AutoCAD workspace within that product.
