Someone made lines with "thickness" help me get rid of them

Someone who had access to the files in my office must have been under the impression that polyline "thickness" was the same as width. At any rate, I have a bunch of files that have a bunch of polylines with a thickness, usually 1", as well as blocks with polylines that have random thicknesses. Anyway, I am wondering if there is a good way to automatically get rid of (ie set a zero value) to the thickness of all lines in a drawing, blocks included.

*note: using Acad LT 2013

Thanks.

Have you tried setting THICKNESS to a value of "0"?

haha...of course. That is what I am doing now to make the files usable. I have been using selectall and then going through each object type in the properties window and manually setting thicknesses to "zero", and that works for everything that is in the drawing, but then I also have all of the blocks that are referenced, and those take forever because I have to BE each one. In all it is taking over an hour on each file...maybe that is the only way, but I was hoping someone had an idea like the command script that emulates the flatten command from express scripts, but for thickness rather than z-position.

Thanks

Have you tried searching for such a lisp routine?

I have tried looking for that, but what I have realized is that I don't know the right keywords to find it. All I have been able to find is people calling polyline line widths "thickness" instead of width...I guess I am hoping that someone out there who is able to pick up the nuances of the question (since they are not a search engine just looking for keywords) will be able to point me in the right direction...

Thanks

You're looking for an AutoCAD lisp routine that addresses thickness in a block. Pick the keywords and search on them as a string.

I think I may have come across something if you are interested.

This routine can be modified to change various properties of a block.

How do you run a LISP on AutoCAD 2013LT?

You might want to look into running a script.

The reference to LT wasn't there originally as I recall. Or maybe it was and I was blinded by the LighT.

I put it in there to begin with...I know it is a problem for this kind of thing...that is why I was talking about scripts rather than lisp routines...

My bad. Firing squad meets at dawn. I trust you'll be there?

Try a search for a diesel macro. LT UnLimited might be a good place to start.

No worries...LT does make things a little more difficult though...
