Create a precisely sized hole in the slab, that goes through only part of the height of the slab.

Hi everyone.

I need to create a precisely sized hole in the slab, like in the image, that goes through only part of the height of the slab.

I created a solid in a Revit family, but it doesn't actually cut the slab when I import it into my project.

I need this to make a model for 3d printing.
Thank you.

Your best bet is to create a family with a void that has a depth.

 

Here is my example

Do I need to create a floor family? And then replace the floor in the model? How would I go about placing the voids exactly in the model?
For me, creating families is a fairly new topic.

 

I had created this family from generic templates.

Thanks for your answer.

The family needs not to be a floor based in case you need it to cut something else other than floors (foundation slab or roof, for example).  Change void to solid and tick Cut with void when loaded, then use Cut geometry to cut the floor with the family in project.

Thank you @ToanDN. I'm doing something wrong, the solid does not cut the floor. I can't use the command you wrote me. I attach the slab and solid family files.

I have attached slab and family files in the comment above.

Thank you.

You need a void, not a solid.

In the whole project file that I'm using it didn't allow me to select both the slab and the void with the "cut" command, even though both are visible. Then I succeeded by opening a section and the two parts were selectable.

What is this? @barthbradley

My screenshot?  If you got to ask, then I must have misunderstood you. I thought you were trying to cut a hole in a slab - on its edge.  That's what my screenshot shows.  Nothing special needs to be modeled. You can use a OOTB structural framing component (beam) like I'm showing.  The beam can remain in the BIM Model as a Reference, no different from any other Reference. Then you can strategically locate and size the hole created by the beam - and changing location and size is easy peasy.  Just move and/or resize the beam.

A question. If I insert this square bar into the slab, shouldn't the slab cut, since I have "Cut with void when loaded" selected? But the cut command doesn't work.

Is there a VOID in the Family?  "Cuts with VOID when loaded". 

 

But why do you need Void? Just use JOIN Geometry Tool (in correct join order) to remove volume at the union.
