killing LWPOLYLINE

[Ernest Burden III]

I used to know how to do this, but I've forgotten. A CAD expert at one of my client's had clued me in years ago...but I haven't used the skills so they're lost.

 

There's an AutoCad entity called LWPOLYLINE that almost nothing else will read from a DWG file. FormZ will, but it crashes on my about 60% of the time I try to import DWG files. I've reverted the version to either v2000 or even r14. Doing an 'explode' in ACAD does not make LWPOLYLINEs into regular PLINEs. But there is a way to select all LWPOLYLINEs and then change a value to make them regular PLINEs. But what is it? The only version of AutoCad I have is ACADLT-97, so it will only open up to r14. But even saving back to r12 doesn't fix the LWPOLYLINEs. Can someone refresh my memory please?

Thank you. I think that helps.

 

But what I was remembering was a variable. I looked at that angle and found the PLINETYPE variable which defaults to , but if set to forces the light PLINES to be treated differently. I think those things together may solve this. Its also hard to figure out when drawings are in paperspace and import in anything else in plain modelspace.

lwpolylines are polylines. i can't remember the history behind this decision, but i think around R14 they added features or functions to polylines and renamed the entity type to LWPOLYLINE (i think it means lineweight)

 

it sounds like maybe the problem is with your older, or lighter, version.

 

if you want something converted, send me the file and let me know what format you desire.....

 

cheers

p.s. i did try the other solution suggested (CONVERTPOLY) and it worked.

Thank you so much for the kind offer. Its not a single problem, its on-going. But for a few years, none of my clients were using the LW lines in their files, so I haven't had to deal with it. But now a client IS, and I'm just having to remember what I did to get around the nasty things. As I mentioned, most programs that open DWGs simply don't read the LWPLINES. You get everything except those. But I think I've got enough tools now to deal with it again.

 

Thanks!

Try the CONVERTPOLY command. It will convert a LWPolyline to Heavy Polyline and vise versa.
