"add vertex" grabbing wrong grip point

[junkinjam]

Hello all,
I'm having an issue with some of my polylines when I try to add a vertex. Sometimes it adds the vertex behind the end point, instead of at the end where I've selected, so that I can continue on with my polyline.
Any suggestions, help, etc. would be greatly appreciated!

Thanks

I assume you are hovering over a vertex grip and selecting Add Vertex. This will always add one after the one selected, but if you don't know the direction of the polyline it can be frustrating.

I keep the GRIPS (System Variable) set to 2 to display midpoint grips on polyline segments. This way hovering over a midpoint grip and selecting Add Vertex will always give the desired results no matter what the direction of the polyline is.

Line from my acaddoc.lsp file:

(if (/= (getvar 'grips) 2)(progn(setvar 'grips 2)(princ "\nDisplays additional midpoint grips on polyline segments.")))
