Cut Geometries

Geometry
1

Hi,
I am new to Dynamo and to this forum.
I would like to know if it is possible to use Geometry.Split to obtain the cut between a geometry and another, or do I need instead to install a dynamo package which already includes a custom node to cut geometry?
If you know where I can find a tutorial or a post with help on this matter I would really appretiate it.

I am trying to cut the solid geometry box to the solid geometry cylinder (seen in the attached image).
I have first selected the two elements to get their geometry so that I can then do the cut

Hi,
welcome to the forum. Do you mean to remove one solid from another?
You can use the node Solid.DifferenceAll:

SolidSub
SolidSub.png946×352 21.1 KB

SolidSub2
SolidSub2.JPG567×669 11 KB

In this case a remove the volume of the pipe from the box.

GeometrySplit works like a knife: you use a geometry (a curve or plane usually) to split another geometry

Hi lucamanzoni,
I would like to do cut geometry to my structure model with reference link file which created by MEP, showing solid generic model for pipe opening. I can see reference revit link family in the list but couldn’t cut the geometry. May i know which node i need to add in? Cut floor slab with link family.dyn (14.8 KB)
Thanks you.Revit 2018 files
