Title: Hidden Polyline Question
Post by: Artisan on November 18, 2004, 12:17:59 PM

Ok, when I draw a closed polyline, like a rectangle for example, using the hidden linetype, my corners do not look right. Instead of little line segments forming 90 degree corners, they look more like a vertical line coming down and the horizontal not meeting it at the corner. Is there a setting or something I am missing here to make this happen? Or is it a scale factor issue?

Thanks

Linetype generation -- I think the variable is pltypegen...or something like that. It only affects new polylines, not existing ones, but you can change it in Properties.

Thanks Kate. Linetype generation is the variable that I am looking for. I was able to change it in properties, but I cannot find the correct name to type in at the command line to change the overall. Pltypegen is not the correct one. Thanks again.

I just reproduced your problem but I haven't yet found a solution to it.  I believe you can get the pltypegen by using the PEDIT command and using the Ltype gen variable.

Quote from: The AutoCAD Help File

Note  Different styles of endcaps and joins of objects with lineweight are displayed only in a full plot preview.

Look up 'Display Lineweights' in the help file.

You're looking for something like the Line Join Style found in plot styles, right?

I think the system variable you're looking for is PLINEGEN.

0  -  Generates polylines to start and end with a dash at each vertex.
1  -  Generates the linetype in a continuous pattern around the vertices of the polyline.

Here is a little lisp that will change all polylines lt generation to ON.

Code: [Select]

(defun c:plg( / s1)
(setq s1 (ssget "x"'((0 . "LWPOLYLINE"))))
(command ".pedit" "m" s1 "" "lt" "on" "")
(princ)
)
