selecting plines question

[Hidden_Brain]

i have a bunch of polylines from which I need to select the ones which have more than two vertices (or alternatively, select the ones which have equal to two vertices). can anyone give me some ideas on how to do that?

To give a very brief background, i exported my SSA model schematic to a CAD file (SSA plan view>right click>export map>to CAD file) that I need to send to another consultant. SSA spit out all the links (pipes & gutters) into a layer called SSA Links. the pipes have only two vertices, but the gutter links have four since I drew then like a trapezium to be able to clearly see them away from the pipes. now I want to separate the pipes and gutter links into two separate layers. I cannot qselect by length since there are long pipes as well.

You can do a quick select, using "Area = 0" This would select Polylines with only 2 Verticies.

"Area > 0" will reverse the results

aaahh!! you are pure genius!! You know, I was a little skeptical since my gutter plines were not closed, but now I see that this works perfect. Thank you very much, i owe you a beer now 😉

please ignore the fact that the pipes and gutters are different colors in the images below, I manually did them shortly after my first post.

The only "gotcha" would be a straight pipe (pline) with multiple verticies. But, in your case i think it should be a clean selection
