Hi, You can add a picture of your graph and join your .dyn file with a wetransfer, dropbox link. ---

You’re using linked documents. You probably need to use the coordinate transform of the link like this : ![transform](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/6/c/6c1bf82d8d454c4809701a8a97ffe1c6477a2099.PNG) ---

Use BimorphNodes, it’s about 10,000x faster and includes purpose-built nodes for clash detection using linked elements. 👍 Details [here](https://bimorph.com/dynamo-bim/bimorph-nodes-v2-2-supports-holistic-linked-element-clash-detection/) if it’s of interest. ---

Thanks for your respons! I have tried to replace the nodes, but it still gives me “Null” in the result. is there anything else I do wrong? ![ClashDetection](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/2/b/2b494f7917d3a0c67862c682a959b92dfb4fa35a.PNG) ---

Thanks Thomas! I have Looked at BimorphNodes and it works fine, but I need A ClashPoint, so I can insert a family, Where there is a clash - Do you know how I find it? ![ClashDetection](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/7/b/7b42411b74179f03d88cc60c2b421418062e274f.PNG) ---
