Trying to figure out 3D

[ciperez]

I currently have an assignment that requires us to turn our 2D drawing into 3D. I am having difficulty with the walls and constructing them. Does anyone have any recommendations on how to begin this process?

Thnx!

Explore these basic 3d commands first:
-Extrude
-Subtract
-Union
-Slice
For the walls start with having the wall lines converted to closed polylines so you could extrude them.

Ok so I made my walls into polylines and I attempted to extrude them and now I am getting this message, "Cannot sweep or extrude a self-intersecting curve."

[nocturne00]

check your polyline, the polyline must be a like a boundary or a closed non intersecting polyline, meaning the polyline being extruded must not intersect itself.
a bit of a remedy is using BPOLY command, select a point inside the wall to automatically generate an enclosed polyline w/c you could extrude.

Loft is another command you can use in place of Extrude. And don't forget Polysoild can be used to make a wall too. Re: Self intersecting. It solids like you crossing some line (literally).

turn all your 2D lines into polylines using PEDIT command /join them all using PEDIT/ then extrude to the height you want. Not sure about your "Cannot sweep or extrude a self-intersecting curve." problem.

Why not use POLYSOLIDS?
Oh, just saw that ReMark beat me to that one.
That is the easiest way to go in my opinion.

PEDIT is not the best option here. And the reference to a self-intersecting curve means that there is something wrong with the OP's geometry.

Nov. 2008? May 2012. Bit of a time gap there, me thinks.

Okay, so you beat me by a generous margin then. A bot before your time.
That would have been shortly after I started drafting.

I was referring more to the start date of the thread and the most recent revival. I travel through time quite often. You should give it a try.
