Hello aqeel222, use the command FLATTEN.
You will have to take a 3D point of vieaw to check all this and mainly the look of the dimensions.
I suppose that you are working in 2D and that the file that you use comes from 3D or includes maybe 3D field curves done by somebody + 2D drawing done by an other person.
I would also use OVERKILL with care ( with all the options but layer by layer ) and PURGE to clean everything.
I use SCALELISTDELALL on the files that I get from other persons ( you have to upload : ScaleListDel.lsp and lauch it ).
Tell us about your test, results, doubts, etc...philippe JOSEPH2014-03-19 07:26:13
