I am trying to make a router template that will be used for a 3d printer. I have been unable to create a wedge with a hole in it. This is what I get.
and the other side
drawing lines at the intersections of the hole does not work.

Push the face all the way through and beyond the angled face of the wedge. Then select the geometry, right click on it, choose Intersect Faces>With Selection and the delete everything that isn’t the wedge with the hole in it.

Thank you
Thank you. I just wish I understood why that works
What part don’t you understand? Push/Pull only works perpendicular to the starting face. Since the opposite face isn’t parallel to the first it doesn’t give Push/Pull a plane to stop at. Instead you have to intersect the sides of the extrusion with the angled face to tell SketchUp where the limit is supposed to be.
Thanks, That helps What i don’t understand is the intersect face command
Faces can pass through each other without creating intersections. Intersect Faces creates those intersections. You can see the edges have formed when I run Intersect Faces. Notice the black edges where the white and green faces meet.

got it. Thanks again

What DaveR said - just because there are physically 2 planes crossing through each other, doesn’t mean they interact or intersect. This is intentional with Sketchup “mentality” - otherwise it would need to create a LOT of extra geometry anytime anything intersected. This way, it keeps it separate UNLESS you explicitly tell it “yes, I want to create extra lines here”.
Also, Intersect Faces will read every face in both objects, and may (in my experience, almost always) create duplicates whether they occur at the intersection or not:
(IKEA Micke desk being intersected with a test cube):
Result:
Created faces from the desk even if they’re not touching the cube surface (e.g. the monitor and random bits from shelves).
It’s extra “trash geometry” that you should keep in mind.
That’s why there are variants “with selection”, “with context”, and “with model”. They let you better control what is included for intersection.
And for the newbies that don’t know where to find the Intersect command, follow these steps:
1 - Select the faces to intersect.
2 - Right click on the selection to open a contextual menu.
3 - Select Intersect Faces in the contextual menu.
So in the desk example above, which option should be chosen?
In your desk example you should only select the cube not the desk. By selecting the desk group you are asking it to intersect everything inside that group too. But if you just select the cube it will only create geometry with whatever it touches and nothing else.
