Hey everyone I’m currently trying to create a dyn script for constructing holes in walls, where there is a intersecting with a pipe/duct. I have at this moment tried a lot of different ways to attempt this problem, without luck. I have come up with a new idea, but I need a little help from you guys. I need to get the intersecting points from the InterferenceCheck.Parse node but I do not know how to get the points out ![](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/2X/d/d07d4d0cabdc106b48a777c829f55ca7a9ef0e08.PNG). ---

Hi @rgs the solid.centroid node will only work if you feed it a solid … Here you’re giving it revit elements. That being said, it wont give you the center of the intersections between walls and ducts, it will just give you the centroid of both elements. there are a couple of topics in the forum about what you’re trying to achieve. Here’s one of them : > [@Wall Openings node from Universo\_BIM package](https://forum.dynamobim.com/t/wall-openings-node-from-universo-bim-package/4751/2): > > Try with this…is a little bit tricky but at the end everything is grouped by wall and I suggest you to use family instance by point to place the void reservation as a solid in the correct place. In this way you can clash not only with rectangular elements but also with round shape. From this you can create your Building works drawings.

Hi, You need to first get the geometry and then get the intersecting points. ![](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/2X/1/19638747931b45e25c7125d08cf169df52c33e8f.png) ---

so it is not possible to get those point’s without using the geometry generator in dynamo ?? ---

Kulkul that look’s awesome.
