Subtraction with Intersect Method

medeek

Has anyone ever tried using the intersect method to perform boolean subtraction of two solids?

Class: Sketchup::ComponentInstance

The Sketchup::ComponentInstance class is used to represent component instances of a component definition or components that have been dragged from the Component Browser and placed (thus, instanced) within the Model.

SketchUp Ruby API Documentation (ruby.sketchup.com)

I really need to do boolean subtraction on some new modules I'm working on but I want to make sure I'm compatible with SketchUp Make and not force the user to go to Pro if I don't have to.

All Solid Tools boolean API methods are Pro only. (This used to be indicated in the docs.)

I have to intersecting cubes in my model. I then run this ruby code:

group1 = entities[0]
group2 = entities[1]
trans1 = group1.transformation
trans2 = group2.transformation
group1.intersect_with(false, trans2, group1, trans1, false, group2)

Which then gives the following error:


Error; #<NoMethodError; undefined method `intersect_with' for #<Sketchup;;Group;0x0000000dd92350>>
<main>;in `<main>'
SketchUp;1;in `eval'

.intersect_with needs the group.entities

group1.entities.intersect_with(false, trans1, group1.entities, trans1, false, group2)

Got it. Thank-you Sdmitch. As always your guidance with the syntax is impeccable. Even after a year I'm still feel like a bull in a china shop

I'm still a bit of a ways away from a boolean subtraction but at least I have something to work with now.
