[BlenderBIM] Element Join

Q by QS_Contractor on 17 Sep 2023, edited 17 Sep 2023 #

I am using the BlenderBIM for QTO. However, it seems that the volume will not be deducted when the elements are overlapped. It will over-measure the volumes of the elements

Actually, is there a function for element join and switch the join order between the elements?

@QS_Contractor hi, where do you find the volume you are talking about?

Also, can you share a picture about it?

Thanks, it would help to find the right answer...

I create a column and a slab with a total volume 0.35m3

When I try to overlap them, the total volume remains unchanged. The correct result should be less than 0.35m3

Unfortunately i don't think this is possible, yet.

Would be nice if you could use one object and bim.add_opening to another object. Similar to how windows automatically apply a void in a wall.

Yeah at the moment, the "quantity take off" method and the "calculate quantities" method doesn't consider the overlapping geometry so one method could be that one suggested by @theoryshaw .

You can btw create your own with a bit of python knowledge :-)

Is there any Python API for BlenderBIM?

M by Massimo on 17 Sep 2023 #

@QS_Contractor sure thing! :-) https://blenderbim.org/docs-python/autoapi/index.html there is a list of all api functions...

But, in general, you can create what you want with python in bbim...
