how can I check if a slab has an opening in Revit and Dynamo?

[firas007noori]

Hi,

If I have a slab or a floor in Revit and I wanted to use Dynamo to check if it has any openings in it??

Any ideas of how I can do that? 

Thanks in advance

Me think you can try to compare the area of the outer footprint versus the actual slab area.

thanks, I thought of that too but how you can do that in Dynamo?

I have no idea.  That will need a Dynamo expert.  Sorry.

many thanks, but the case of the pipes are already designed and Dynamo can actually find their locations, but how you can define if an object or a slab has a hole in it?? in this case, you Dynamo to analyze the object for you to find where the hole is?

This was the page I was looking for originally...  https://dynamonodes.com/category/standard-nodes/revit/

But basically it sounds like you are looking for an interference check... https://forum.dynamobim.com/t/clash-detection-using-dynamo-revit/11332/5

I do appreciate your help dear, but it is exactly the opposite of what I want, in the pipe example, the location of the pipe can be found and so you can open a hole in a slab for it, for me, I have a slab in Revit and I want to detect if it has a hold in it or no??

Many Many thanks in advance

Maybe a Priest could help you determine whether or not the slab is holy. 

Get it? "Holes" ... "Holy".    

ugh.

That is an interference check between pipes and the floor...if there is a collision (no holes) then it will report that...if there isn't a collision (Has holes) then there are no issues.

I do thank you again, but there are no pipes in the case I am working on, it is an architectural check for any possible loaded floor, so if you have any idea of how to check the existence of a vertical opening in a slab, that would be really appreciated.

Many thanks in advance

I think the steps are like:

- edit the floor boundary, copy the outer loop, close

- paste to make a filled region or another floor, get the new area, delete

- compare new area to original: if equal = no holes, if more = holes

- write the results to a parameter of the floors

How to put it together in Dynamo?  I have no idea whatsoever.  You are better off asking the question over at the DynamoBIM forum.
