PukaWai Posted February 15, 2018 Share Posted February 15, 2018 I need to be able to see the direction of a polyline. I've tried the dirarrow.lsp that comes with Map 3d - works but is only temporary. I've seen other lisp that will insert blocks along the pline, but that's no good if you alter the pline. The best solution is a custom linetype with embedded ">" character - if it would only work properly. The issue is that the linetype only follows the polyline direction on straight segments, on arc segments it seems to depend on the arc direction (CW or CCW) regardless of the pline direction. I've attached a .dwg and a small screenshot. If you grip-edit one of the plines with arcs, you can see the "direction" change as the arc changes from CW to CCW or vice versa. parcel.dwg Quote Link to comment Share on other sites More sharing options...
eldon Posted February 15, 2018 Share Posted February 15, 2018 Have you tried turning on the Linetype Generation? Quote Link to comment Share on other sites More sharing options...
PukaWai Posted February 15, 2018 Author Share Posted February 15, 2018 Think I've used that once eons ago! Unfortunately it seems to make no difference to this problem. Thanks for the thought... Quote Link to comment Share on other sites More sharing options...
eldon Posted February 15, 2018 Share Posted February 15, 2018 That is curious, because it worked for me. Quote Link to comment Share on other sites More sharing options...
PukaWai Posted February 15, 2018 Author Share Posted February 15, 2018 Ah, not so curious. I thought that plinegen was just a global system variable, but now I see it is also an entity property. Problem solved! Thanks for the tip. Quote Link to comment Share on other sites More sharing options...
ela3war Posted May 19, 2018 Share Posted May 19, 2018 Simply use reverse command Quote Link to comment Share on other sites More sharing options...
eldon Posted May 19, 2018 Share Posted May 19, 2018 Simply use reverse command How does that help to see the direction of the polyline? Quote Link to comment Share on other sites More sharing options...
BIGAL Posted May 20, 2018 Share Posted May 20, 2018 I like eldon's idea, in the past exploded the pline pick the 1st section reversed if required then rejoined this made arrows go in correct direction. Quote Link to comment Share on other sites More sharing options...
