Triangle angle sum > 180!

If you Remove Doubles and it merges a total of more than 1x10^33 vertices, a virtual singularity may form in your .blend, causing a local disturbance of Blenderspace that can cause all sorts of geometric weirdness like interior angles > 180 deg. :eek:

Try it sometime! :eyebrowlift:

I’d worry that would cause a virtual black hole which would suck up all the bytes in ram and on my hard drive, and if it escaped over my internet connection onto the www, could wind up destroying civilization as we know it. :eek:

This is how I did it:
1. [alt-x]: Erase all
2. [kp_1]: Front view
3. : Erase cube (if any)
4. Add -> Plane
5. Merge the 2 lower verts at center
6. And there you go

Just realize that this will not get you an equilateral triangle. You will get two angles of 63.43° and one angle of 53.13°.

Well… That is true… Guess my triangle in my model is not completely equilateral, I only used 12 decimals when I calculated the position of the merged vert, because I didn’t quite figure out how I was supposed to make an equilateral triangle at first, now I know a few better ways to do it…

Considering that the described method will result in a triangle where the height equals its base and you want the height to be sqrt(1²-0.5²). All you need to do after your procedure is to scale the triangle 0.866 on its height.
