Intersecting Solids

[fragmuffin]

👍 for an intersect command.

Example a remake of wikipedia's intersect CSG example

import cadquery as cq
from Helpers import show

sphere = cq.Workplane("XY").sphere(7.5).translate((5, 5, 5))
box = cq.Workplane("XY").box(10, 10, 10)
intersection = sphere.intersect(box)  # error, not implemented

show(intersection)

Workaround can be found in this gist

or am I missing something? (entirely possible 😉)

This is easy to implement. The intersect method is already implemented at the low level in shapes.py.

App that's needed is to add a method into cq.py that's similar to cut, but uses Solid.intersect instead of Solid.cut

A PR would be welcome

I can't help but feel that you've set me up for success.
regardless, I feel warm and fuzzy.

[dcowden]

ha, you are quite funny ( evidently, in addition to being fuzzy).

+10 points for adding a test case, and thanks for the contribution. Thanks also for the little whitespace cleanup you did.

Is it WIP or are you ready for me to merge it in?

[easyw]

common is different from intersect?

[dcowden]

They are the same. intersect is the name I'm most familiar with, and is commonly used with CSG. But 'common' is what FreeCAD calls it.

@dcowden
it's ready to merge, just a simple change.

actually, the WS cleanup was my editor, sometimes it's useful, but other times I get a to-and-fro between conflicting editors... either way, you're welcome 😉

[dcowden]

Awesome, ok thanks again for the contribution!
