lines at various "Z" heights

[trhoads]

Hello all,

 

I have a CAD drawing from a civil engineer. And when they do topography, they draw the topo lines at "Z" heights corresponding to the grade change. Don't ask me why, it is very frustrating.

 

My question is; Is there a command that will allow me bring all of those lines down to the same "Z" height at one time, without selecting each individual line and moving them one at a time?

 

Any advice would be great, I am at wits end trying to figure this one out. Thanks in advance.

Go to http://www.cadalyst.com, and look for the heading "get the code"....you will have to register, but there is a lisp file there called "flatten". This will take everything and put at z=0.

 

By the way, I love to get files with topo at the coorect heights...makes great terrains and saves me the time moving everything up or down.

That's a great tip Chad!

 

I'm not sure what civil engineers use to create the topology but I seriously doubt the ones I work with ever look at what they do in 3d. The reason I say that is "stuff" (substitute explitive) I get from them looks great from the top view in ACAD, but if I tilt it, the lines are a jubled mess. I mean one line may have a point at -2000 in the Z and the other endpoint may be at +5000!? From the side or any other perspective is looks like a messy ball of yarn.

hey man, there's a way to do that, try to leave all the lines, save them as a block and when you insert that block again in the drawing put in the z scale factor 0, and that's all...

I hope this work....

If the lines are all flat can't you just highlight all of them and under properties change the elevation from*varied* to 0.

Just got a chance to get back to this, sky, your suggestion was the easiest fix. Thank you very much, it worked flawlessly. Thank you to everyone for your help. I appreciate it very much.

if nothing works and you are ready to sacrifice text converted to plines, try using wmfout and wmfin back to acad.

I wish I could get my civil engineer to do this. Can't tell you how many hours I have spent moving them myself.

here ya go

Depending on the version of cad you are using. Use express tools, there is a command in there called flatten, this will flatten most all objects.

if you still need a copy of "flatten.lsp" ?? please let me know

 

i can/will email it to you, it seems to have been around for a while

so i dont Think That There is any copyright issues with sending This

we use it here for the same Issue, civil non-0 z coordinates

Thanks
