Convert a 3D Polyline to a LWPolyline?

[SteveK]

Does anyone have a lisp routine to convert a 3D Polyline to a LWPolyline?

 

I'd rather avoid the process of FLATTEN->EXPLODE->PEDIT->JOIN because I have lots of them.

 

Ta.

You may need to use Convertpoly to make a lwpolyline

Hi,

 

I can't get the link to work, (Content Encoding Error with firefox & Page Not Found with IE ??)

 

And I tried CONVERTPOLY (as well as with FLATTEN) and whether I choose Heavy or Light it just says "0 polyline objects converted."

It's a new week, so to bring to the fore one more time, does anyone have a lisp for this?

Steve1, the link works here(?).

 

Try it again, nice.

Ahh, works today, and it works good too. Thanks Larry for the link & Tankman.

 

 

A side note if anyone feels like commenting: The code is different - there's no local variables and it's the first time I've seen vla-selectonscreen used instead of ssget. I wonder if that is why you can't escape/cancel out of the selection set. Always things to learn..
