#6 Hole-y fail.

[MadWookiee]

Hello,

I'm expecting to carve a hole in a block, but I don't want to mill the entire surface of the block for this. I would want to select "the faces of interest"

So I used Blender and with a boolean operation, made a hole in a cube, then removed the faces I don't want pycam take care.

Here, I don't know if pycam is able to compute path "out of nowhere", with a non-plain solid.

But when I try to open the generated STL (joined, a six-sided-hole), pycam give me a waring : "Skipping invalid triangle:[...] (maybe the resolution of the model is to high)", with 25 similar messages, and my model is not displayed.

I tried to move the model in space, to scale it, I always get the same message.

At least, is there a way to now why a triangle is not a valid triangle ?

PEBCAK or Bug ?
