# Finding 90 degree angled vertices among selected lines

Hi all,

My name is Eric Ma, and myself and 3 others represent a subteam of AguaClara Cornell dedicated to using Featurescript to model our plants. We just switched to OnShape, and are new to Featurescript, so we'll probably be showing up on the forums much more frequently. We're excited to learn more about the language, and all help would be greatly appreciated!

Our current project involves inserting elbows into a selection of created pipes. This is a modification off of the current Beam feature, which is being used to model pipes. The current feature takes an input of edges, and creates "beams" from the edges. Our goal is to find all the points within the given selection of edges that have a 90 degree vertex, and insert an elbow of a specific size there. Our current issue stems from finding the specific 90 degree points. We have found all adjacent points with qVertexAdjacent, but the issue is we're unsure how to find that the vertices that only have two lines stemming from it at 90 degrees. Any help would be appreciated, on this specific question or on Featurescript in general.

Best,

Eric Ma
