Hi all, I cant figure out how to place points between two intersected geometry, Ive tried Geometry.Intersect node but its not working out for me. Any hints? ![test](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/1/e/1e82a11d3b3776f98954dac52865d6dbf98232ff.JPG) ---

I would search for “clash detection” topics for this: > [@Clash detection and wall opening family](https://forum.dynamobim.com/t/clash-detection-and-wall-opening-family/5536): > > there is a nice one to find clashes from bakery . can find clashes, and I am able to create a generic element in revit, but I would like to place a wall opening family instead. Is there a way to place this family at the clash point with the dimensions of the intersecting solid ? ---

Hi, what geometry did you feed to the **Geometry. Intersect** node? ---

Thank you That’s really great which is what im looking for but Im also trying to find the location of the clash intersection to flag and prompt the user of the clash element. ---

I’ve feed in the wall and the pipe element, but its all working now because it was just hidden in the dynamo visual screen but the problem I’m having now is that it became a solid geometry which i cant seem to grab the location of it. Any clue? ---

I have seen solutions about that but never tested it myself: > [@Linked Model Element ID Extraction From Navisworks Clash](https://forum.dynamobim.com/t/linked-model-element-id-extraction-from-navisworks-clash/9966/8): > > hi Beau I’ll explain the principle rather than giving you a complete solution. Say you have 2 clashing objects- a wall and a duct. The ID of the wall is 210338 and the duct is 709842 When you use the clash detective in Navisworks and export an XML file of the clash, you get information such as the clash number, XYZ coordinates of the clash, and IDs of the clashing objects So using this data in Dynamo, you can mark the position of the clash- say placing a family at the XX…
