Send all to elevation zero

Hello all,

I got a couple of drawings that look fine when I am in top view, but if I change to front or any other view there are lines, and text and dimensions placed at different elevations.

Could you please help me with a lisp that will let me select and send all to elevation zero and to keep the layer properties for each element in the drawing?

Thank you

Have you tried the Express Tools FLATTEN command?

This macro has been known to work too.

C^C_move;_all;;0,0,0;0,0,1e99;_move;_p;;0,0,0;0,0,-1e99

Another option would be the old CHANGE command and its ELEVATION option.

ReMark,

The macro gives unpredicted results, Flatten is working only in top view, and Change is not working at all.

Perhaps a different approach will solve the problem.

Thanks for your suggestions

You would not like my 'different approach' suggestion.

Attach a copy of the misbehaving drawing to your next post. Someone here will take a look at it. Maybe they will have better luck.

ReMark,

I found a way to work around the macro you provided and after a couple of "trial and errors" a came to the desired result.

Your previous suggestion works and for this I own you an apology.

Thanks.

No apologies required. Glad to hear you got it sorted out. I was going to suggest drawing everything over from scratch! LoL

I use this one which I created YEARSSSSS ago

Still working fine for me
