Geometry within a boundary & Geometry outside another geometry

dynamo
#1

Hi all

  1. we want to keep a set of given geometry within a geometrical boundary, how do we achieve that in dynamo? is there a node for that?

  2. we want to ensure a geometry is NOT within another geometry foot print, how do we achieve that in dynamo? is there a node for that?

Thx in advance

Hey,

I think you can do what you’re after, with a few nodes… Here’s an example which gets geometry from a scope box to find what’s inside it…

Here’s one to find what’s inside an Area…

Depending exactly what you mean by Keep, you could use a node to select in Revit or to make a group? If you select everything in a view, for example then filter out what’s in the geometry, you’ll be left with everything else?

Hope that’s of interest,

Mark

Thanks Mark! we’ll look into your solutions and see if they are what we are looking for.

element.geometry and geometry intersect nodes might come in handy here

is there a node that will delete a geometry if a Boolean is false?

Dynamo geometry isn’t deleted - it’s created and not passed upstream. If you’re looking to delete a Revit element, Tool.Eraser, which I believe is in the steamnodes package should work.
