Hi all, I’m trying to place piles in my Revit model using the FamilyInstanceByPoint node but for some reason Dynamo is reading the Z values of the points correctly. I’m trying to place the piles directly underneath a number of capping beams but as you can see in the image, the piles go right through the capping beam. The placement points are derived from a line that runs along the bottom centre of each capping beam. ![Piles](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/6/8/683a463862e9112a11f5ab9f5a291150e9122499.PNG) ![Script](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/5/9/5938ab136fc89fdbeb6bd35f246c86dd7fe9babf.png) [PlacePiles.dyn](https://forum.dynamobim.com/uploads/short-url/rrrESisfEs7FGfPLErcLiw1vvni.dyn) (42.2 KB) If I run the script for a second time, the piles are then placed at the right height (below the capping beam) but I don’t really want to have to run the script twice. Any ideas? May thanks ---

Hi, Please add your graph and a picture of your graph with all the previews enabled under the nodes. [https://forum.dynamobim.com/t/how-to-get-help-on-the-dynamo-forums/4677](https://forum.dynamobim.com/t/how-to-get-help-on-the-dynamo-forums/4677) ---

Hi, Sorry I had strip back my script as it had other nodes or UI that made it rather large. I have included screen shot and script on my original post. Thanks ---

For me, it works well on the first attempt. (Revit 2017) Are you in automatic mode ? ![Place%20piles](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/0/2/02865859b0b8a1b7bb15ffbce3fcf440b0a59e03.png) ![Place%20piles%202](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/8/9/893a388945bd31c4b7870328b2b6bbe391e6a9ee.png) ---

Hi Alban, just tried placing piles with dia. wider than the base of my capping beam, just like you’ve shown in your image, and it worked the first time i ran the script. I had a sneaky feeling that this might be the reason it worked for you the first time you ran the script. If you’d be so kind to try and use a beam that is wider than the dia. of the piles you are using, and see if my theory is right? many thanks ---

Unfortunately my pile family is not face based but thanks! ---

Hi Renzo, It can’t be the reason. It is rather like a calculation was made after the piles were created and a node passthrough was missing somewhere, but I don’t see where for the moment. ![Piles](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/0/a/0a6fd649a036cf35167af76c65165c984b5f8e8a.PNG) ---

Hi @Renzoj14, There is something strange in your Revit file. When I copy the pile and the Capping beam in another Revit projet, I haven’t to run twice your graph. The solution will be to set the Height Offset once the piles are created. ![Modify%20Heigt%20Offset](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/5/f/5f07898aa88f3835b9043b93e1ed9f90d3bbf7de.PNG)
