auto void

[shayansayyah1996]

Hi everyone

I need a help

I wonder is there anyway to automatically made a void in the intersection between structural beam and wall

we have a ifc structural model and we want the wall cut of from the beam

how should i do that?

Thanks!

You possibly can do something with Dynamo. With Dynamo you can find intersection of geometry and then add void at that location.

It might get complex depending on the shape of the voids and the rules you want to apply.

Example, what if the beam comes in at an angle. How should the void be applied, at the same angle or perpendicular on the wall. What about tolerances. Or what about things like I beams. Should the void follow the shape of the beam or more box-like.  Also how irregular will the void shapes need to be.

You could start simple that might apply to the bulk of the openings and do the rest manually. Later make it more sophisticated.

You also can look for (paid) add-ins, for example on the Autodesk app store.

Something like this? 

Join Geometry.

HI

thanks for your reply

I do the opening with edite profile but I wonder if there is a quicker solution?

beams are ifc model

Dynamo is the quickest option. If you are not familiar with Dynamo and opt to do it directly in Revit,  then use a wall based family with a cut opening, instance dimension parameters, and place it where the beams are.

You can also copy the IFC beams and paste aligned in place, change them to concrete or wood beam type with the same bxh dimensions as the steet beams, then join them with the wall to create opening. Hide the copied beams when done.
