LSP to move all 3d objects to 0 plain |
|
|
We have a model of buildings that were create in another cad program. The
building were set on a 3d terrain so they are Z values. Is there a LSP file
that can take all the buildings and set them on the zero Z plain?? Thanx.

I don't know of anything that will convert all kinds of entities into 2D.
Depending on the type of entities used to make the model, a simple lisp like
that below will do it. It won't change the thickness of entities to 0, and
it won't flatten solids, or blocks with 3d relations in them, so you may be
into a multi-stage process. Copy everything between the lines into a file
named flat.lsp, and put the file in your path. Use APPLOAD to load the lisp
file then issue the command FLAT at the command prompt.
There are other routines around, but they have the same effect, I think.

You misunderstood my intent. I have buildings floating above and blow the
ground plain at elevation zero. I want to move down the buildings that are
above ground zero and move up buildings below ground zero. All to the same
ground plain. I don't want to alter or modify the object.

That's done with the MOVE command. I'd suggest splitting up the screen into
maybe three ports and set one of them to look at the model with the XY plane
perpendicular to the screen. Then you can use point filters to get them
level with each other. I hope there isn't a small town's worth of buildings
there......
