Extend last created Pline.

Recommended Posts

I like to extend the last created polyline from its last endpoint using autolisp.

Just use : "Line" -> "Length" options during pline command, for arced extension, just use "Arc" and graphically arced segment will continue to display as tangential continuation of previously drawn line or arc segment...

 

HTH, Cheers...

Or if you already have drawn pline, just use "UCS" "E" and pick point near last vertex of pline... New UCS will be oriented so that its X axis will point toward tangent orientation of last pline segment... Then you just use pline command along with combination of ORTHO (F7) option and draw newly created pline, or if you want arc then use pline command, choose end vertex as starting point (previously UCS has to be set as tangent of last segment), choose "Arc" as starting option, followed with "Direction" option, and again use combination of ORTHO (F7) option to pick next point along tangent or normal and graphically arc will be drawn showing position according to your last picked point preserving tangent or normal orientation from last segment so it'll be extension of your pline... After all that you just pedit your pline and newly created pline (multiple) option and use "join" to join them into single pline entity... So you don't need lisp for this task...

 

HIEW (Hope I explained well)

Cheers, M.R.

Marko F8 for ortho

 

I agree UCS OB pick last segment make sure F8 ortho is on drag end point with mouse and type distance required for extension then ucs W. Probably take longer to write a macro than do it.
