Hey, MATH PEOPLE!:
2 related problems: you're cutting a pipe at an angle. What's the formula for determining the angle to achieve a specific >length< of cut? IOW, 90°=diameter of pipe, 0°=infinite.

2nd (and real problem): you have a plate you want to fit tilted at an specific angle over a pipe. How long is the oval slot you need to cut in the plate? (Supply a generic equation.)

THANKS!!!! :bowdown:

My first question is: Why do you care? You're working with a 3D application. Put the pipe in a foreground layer, the plate in a background layer, position them at the angle you want, Boolean (or not) and measure.

Use trig.

Oh, I thought I'd use a harpsichord.

The resulting slice will be an ellipse; Major axis will be pipe radius / Sin (Angle), minor axis is pipe radius.
(Sine is used because Sin 90 = 1; Sin 0 = 0; At a 45 degree cut (.78539816 Radian), and a radius of 1, Major Axis = 1.414213, Minor Axis = 1.000).
