Space Creation Tool |
|
|
I do some facility management work and have a question about making a utility.
I am given floor plans that have 2d line work for walls. I would like to be able to pick the interior walls, set a distance and have the walls offset to the distance set, then extend and trim as needed, then join ala Pedit. Maybe in plain English. I would basically like to calculate the area of a space to the center lines of all walls. Doing this one office at a time.
Any help even getting started would be awesome. I have some experience in LISP and VBA, so please be gentle.

I know you will get better answers, but here's something to consider in the
meantime.
If the wall lines are contiguous, look into the use of the BPOLY command to
do a ray trace. You'd have to isolate the wall layers first. BPOLY delivers
a closed polyline from a point picked inside a closed boundary of line and
arc segments. You would then offset a new polyline to a point outside the
closed polyline using a point created opposite the original pick point
(original pick being INSIDE, you calculate to and return a point OUTSIDE).
All of this could be accomplished with a single pick.
The advantage of starting with polylines is that an offset of a closed
polyline is a closed polyline. The first is temporary (traced walls), the
second is the keeper (centerlines), based on your note. Personally, I would
calculate the interior square footage of each room, not the square footage
to the centers of walls.
