Hello all,

Thanks in advance.

See attached.

Put both files in a location that is in your support file search path.

Tweak as desired.

You have to go 1 more step to get the vertex showing by explode the lines.

hy,

Thanks for the fast response. I load the type of line but it wil not allow me to explode more then one time. and after the first explode i only get this. i attach the screenshot.

Is that a new feature in 2017 [which I haven't loaded in yet]?  In AutoCAD 2016, I can't Explode linework using a linetype with Shapes, and get the Shapes broken out.

A routine could certainly be made that would construct a Polyline in that fashion, similar to [but with different point-defining portions than] what InsulBattPoly.lsp with its IB command does [a much-more-sophisticated example than this shape would require].  It could be made to [as IB does] ask the User to which side they want the teeth, and presumably wouldn't require IB's center-justification option.

Does that sound like what is needed?

EDIT:  A question....  In the case of curves [Circles, Arcs, Polyline arc segments, Ellipses, Splines], would it be essential that the parts that are not the teeth follow the path curvature?  Should it be as on the left, or would the one on the right, with straight pieces between the teeth, be acceptable?  [The latter would be infinitely easier.]

The tweak I would suggest, if it's important that the proportions be more like the original image [non-tooth portions apparently the same length as teeth], would to either omit the pen-down part at the end:

A,1.0,[Angle,angle.shx,S=1],-1.0

or for [I think, without testing] more balanced results at the ends of things, make the total of the two pen-down portions one unit:

A,.5,[Angle,angle.shx,S=1],-1.0,.5

Perhaps @Patchy is referring to "exploding" the linework down to its most basic elements using WMFOUT and WMFIN, or a modified TXTEXP command.

[Their link in Post 6 appears to be in the latter category.]
