<p>but after getting the same results with a definition not using pull points, i would say it works ok.</p>

<p>Yes i thought of that too and since you mentioned too, i figured i had to try what pull points does (closest setting) with other components to verify if pull points works ok.</p>

<p>the reason i I have been saying 'neglecting edges ' is because some points seem to be closer to another edge than the one they are connecting too..</p>

<p>Which input needs closed brep?</p>
<p></p>
<p>pull points is not neglecting any edges. it just uses those which are closest to the points so many points could end up in the same edge.</p>

<p>yeah i tried surfaces but it didnt work. the input also needs to be a closed srf ..</p>
<p>still though i dont understand as the pull component seems as if its neglecting some edges based on the previous photo..maybe the points are on the same plane? </p>

<p>You are projecting only in edges and not surfaces. In pull points component you are using closest only, meaning that many points end up in the same edge. Even if you did pull your points in surfaces too, similar result would happen, because in your case i believe the closest rule does not work without having the curve going through the irregular brep. (Unless i am missing something, geometry always surprises me)</p>

<p>i did not put too much effort organizing the curves that form the polyline, meaning which ones of the brep perimeters will be chosen (i just listed the first item in the list).</p>
