Cutting wall with void

[ziutek72]

Hello everyone

I am working on a project for my studies but i am stuck at the final step (i think so). I want to create void openings for windows in Revit. Unfortunately Element.Cutgeometry doesnt work although i can cut wall and opening manually in Revit. I would be grateful for any hint how to solve my problem. I have read this topics:

Cutting Walls With Void Object Family

Hey guys, I thought this should be really simple but have gotten stuck, any help is appreciated! I am trying to build a tool that will cut multiple holes in walls (rough openings) using families of void objects that I have created. I tried to follow a few examples and came up with this but it doesn’t seem to do anything! Home.dyn (8.2 KB) This is the cutting void Rough Openings.rfa (436 KB)

Cutting beams with multiple voids

Hi, You can use Element.CutGeomtry from Clockwork or Cut.Geometry from Hot Gear. [image] I also suggest to cut the beams only with the intersecting voids otherwise your Revit file size will get very large (Tool Get Surrounding Elements from SteamNodes works great). Cheers Giovanni

Lots of Families to change Solid to Void Identity Data

I should have mentioned that at the moment I am using the workflow below to cut openings on my structures which requires voids. [1] More than happy to take another approach if works better taking solids or any other mean, ultimately I am aiming for is to have my openings matching the MEP model containing all Mechanical Equipment as openings.

and tried to follow advice given in them but without success. Void family i created has checked “Cut with voids when loaded”. I would upload my files but new users are not allowed to do so.

Hi i think you need to use Element instead of Geometry(Solid).

You, dear Sir, are absolutely right. I am so grateful that i cannot express my gratefulness.

Hi,
I am doing something similar but instead of placing a window void I want to place an outlet void. This seems like a great script that is right along the lines of what I want to do but when I run this graph it doesn’t work for me. I am trying to troubleshoot and one of the differences is the element I am selecting. What element are you selecting in the “Select Model Element-WINDOW” node?

Thanks!

Hi
I selected window (select element in dynamo and click on element in Revit) wchich was regular solid with window category. Now the model in Revit has wall-based windows and dynamo project is changed to select all windows and walls. It works so far.
