I am working on a residential project where we have a 100mm wall cutting into a concrete wall. In Revit I can do thisusing the cut tool, selecting the concrete wall and then the wall which cuts in to it, the result I get is a hole cut into the wall, like below;
Because we’re using groups and both walls are in different groups I have to do the cut comment on each level for each clash.
In the script I am gettign all warning and filtering out any which are for the “22_OOA_stellat 100mm”, from here I can get the pairs of walls which overlap and and want to join. All this is fine, there doesn’t seem to be an OOTB cut geometry node so I am using one from Clockwork.
For some reason the cutting is not working as expected, see below
Yeah, kind of. For your first image, I think the underlying API call would just make it like a wall recess instead of cutting through the concrete. I suggest working towards a script that copies two concrete walls putting them at both sides to emulate the post-cutting result and just place a 100mm wall in the middle.
Thats unfortunate it’s not something which can be done, would be very handy!
We don typically model the walls in multiple parts like this as in some cases the concrete is also above the thinner wall. We may have to look into doing it or cutting all the walls on all levels, the former being (probably) less work.
Could you just build a family with a void cut to place on the walls at the appropriate location? You could make it dynamic to fit wall depth and have an adjustable length or position if that’s not consistent. It seems like cutting the actual walls is already extra work.
It’s a bit of an odd one and the above is only part of the story.
Were using the 100mm wall to host a door family, the wall is acting as the backer to the frame(stellat, and I’m not sure why its not included in the door family). The host wall has two finction, I guess, one to host the door and second to cut the opening into the concrete. We typically remove the structural elements once a structural model is shared, or when we share we ommit any structure we have. because we’re working with groups the cutting has to be done on each level as neither wall is in the same group.
The wall is convenient to have for hosting of the door and indicative of the space we require for when the structural engineers start modelling.
I think there is a void in the door family which would cut the wall, I have to see how it was built and if it can be used.
Can you just include the backer wall in the family instead? It seems like this is more of a workflow issue than an automation one. At the very least, it seems like you should be building around the door placement as that’s the manual input you need to provide. Everything else should be able to be automated around the door’s location.
