Getting rid of 3D lines!

[Nick_101]

Hi Guys,

I have a problem with 3D lines in a drawing that I want to be 2D!

I've tried 'IRON' and 'FLATTEN' to remove the problem, but I'm getting unexpected results. Can anyone suggest a good routine to do this job.

I'm using AutoCAD 2009 and 2010!

 

Thanks

What kind of results are you getting? Error codes or just the commands appearing not to work?

Have you checked to see if there is a thickness to the lines?

How about the old CHANGE command and the ELEVATION option?

[BWells]

Could it be that the lines in question are twisted. (Meaning: the UCS's of the segments are different from segment to segment.) I've seem it happen before when receiving client drawings. Just a guess.

Should that be the case I've just exploded it down to 2d lines and rejoined the segments. then it's just a question of reassigning the elevation.

Use this one... it's the one has worked better for me, works for lines, polylines, I think, arcs, attributes and other stuff...

 

the only bad thing is that it does nt allow for selecting.. it goes for all drawing objects

 

 

and you can complete the task by using the command line version of the command... change... then all.... then properties... then elevation... then 0. (zero)... and done

Flat.lsp

That's funny. Flat.lsp uses the CHANGE > All > Properties > ELEVATION > Zero approach. Where have I heard that before? LOL
