Hey all,I know there is probably an easy way to transfer a simple polyline shape from a clients dwg into mine without the hassle of having to purge all their layers and blocks. I tried the WBLOCK command and that seemed to work well. Just want to weigh my options and focus on the easiest/fastest way possible. Any other suggestions?

Why wouldn't copy/paste work?

Because it copies all the entities of the clients dwg. So afterwords I have to purge all their blocks, dim styles, text styles, and layers. Even if none of those were in the PLINE that I copied. For some reason all that stuff gets transferred too.

It doesn't bring it all in.  Some maybe but not all.  Anyway, you should have a script, macro or lisp routine that automatically purges any unreferenced objects which should be run prior to saving and closing your drawing.Have you tried isolating the layer the spline is on prior to doing a copy/paste and see what it does/doesn't bring into a new drawing?

True. Still an annoying burden though. I'm not too familiar with any of those routines but I've been thinking about researching into it a little bit more. If no one else provides another answer I'll go ahead and look into it. Thanks John.

Just saw your edit John. What I tried before was making a line on the layer in my drawing, copied/pasted that into the clients drawing, matched the properties to their pline, and then I would copy/paste their drawing into mine. Still had the same result with the random blocks, layers, etc.

Something is off with your explanation.  Why would you copy a single line from your drawing to the client's then copy their entire drawing into yours?

Sorry, copied/pasted their PLINE that now has my layer properties from their drawing into mine. Not the entire drawing.

Why?  You open both drawings.  Copy their PLine or Spline or whatever entity/object from their drawing to yours THEN you change it's properties once it is inside your drawing.  Or change the object's properties to layer "0" then copy/paste it into your drawing.  You're introducing an unnecessary step.

So it comes in as my layer and I don't have to purge theirs. My other option was to make theirs a "0" layer. I understood it was an unnecessary step. Hence why I'm searching for a new and better option. 

To each his own.  Have fun.

At first copy this object then paste it in new drawing and select similar object & change object Property. That's ok.and need any other so use "convertpoly" command!
