Move All Lines to 0 Elevation

I am sending a drawing to an outside firm that wants all our lines to be sent to them at elevation 0. If I export my drawing to a ACAD file all the feature lines turn into polylines at elevation. Is there a lisp routine or someway faster than selecting lines, contours, ect. and manually putting them down to 0?

Thanks,

I am also trying to drop all our plan design lines to 0, unload all xrefs, type in "flatten", select all design lines
and they all go to an elevation of like 3244 something.
Why not 0?

also noticed when you flatten leaders with text they explode or break apart, and you cant move the text anymore and have the leader stay with it!

The only problems I've ever had with flatten is if you chose to remove hidden lines- things start to dissapear. So, I've always been able to use flatten and the items have always gone to zero elevation and not something else.

Have you tried selecting all your stuff, then using the properties window, change your selection set (where is tells you how many items selected) to each item, like lines, plines, txt, ect.... and set your z elevation to zero?

Hope this helps, and, I'm out of ideas on it. Maybe somebody has lisp routine they would be willing to share.

One other thing, when you flatten everthing, and it puts everything at some random elevation, is everything at that elevation? If so, them use the move command and move by the z elevation down.

Just throwing out all ideas to the table...

I have had this happen a few times myself, when you select a poyline the elevation displays as a strange nonsensical number.

Instead follow this workflow.

Explode from Featurelines to 3d polylines.
Convert from 3d Polylines to 2d poylines.
Now explode these polylines to lines.
use flatten or use the properties and change Start/End Z levels to zero.

Use Pedit Multiple to join all lines together again.

If they're just lines or Plines you can change the elevation en masse in the properties window

Normally that will work but there is some kind of a glitch which produces a polyline with a very strange elevation value. When you change the elevation rather than moving vertically it relocates in the horizontal planes.

That's why I sudgested the method as stated, it's the only sure work around that I have found works.

I've noticed if you have a line with different start and end elevations, convert it to a polyline and they try to change the elevation the line will move into outer space.

I imported a plan from AutoCAD to sketchup to form the model then I noticed that all the lines are not in a same line...I checked my cad file and noticed that it has become a 3D ....can I make my all lines to the same level?? I used flatten command it is not working...plz help

FLATSHOT is better, but it does the entire drawing at once. It also can flatten to current isometric view. Make sure your view cube is on top if you want straight lines when you get done
