Angle/inclination of a cone? 123Design

[Andreas_58]

Hi,

How do you find out the angle/inclination of a cone?
I’ve been playing around with the measurement tool but can not find out.

Thanks!

Hi @Andreas_58 if you know the perpendicular height and the radius, you can calculate the angles. No need for math, here’s a handy online tool:

Another trick is to draw construction lines, measure your lines rather than the object itself.

Thanks for answer, I actually tried that calculator but my cone has an open end. It’s not pointy.
Here’s a 2D-sketch showing what I’m trying to measure.

Thanks, that worked!

But it feels like a somewhat long walk around something that should be quite simple.

Not if your construction lines are already there. Most high end software, you can achieve the lines and measurement with about 3 clicks.

123D is quite powerful for the price ya pay
