I want to challenge everyone to draw a right triangular pyramid.
I found that building a right triangular pyramid with a few simple steps is not so simple.
Tomorrow I will show the solution. Good luck! :slight_smile:

you mean as in the picture?

You noticed a problem haven’t you ?:slightly_smiling_face:

If the peak all 90 deg…its easy


Yes, but all edges must be equal. In my example - 10 mm.

Keep trying :slight_smile:

But it have 60 deg on the sides…

I made it a long time ago

Its called : tetrahedron

Great solution, but as I said - it should be in a few simple steps. :slight_smile:

Man some wrong with angles

But I got it :upside_down_face:

Can you show the steps? :slight_smile:

There you go :video_camera:

Here is the sketch as well :slightly_smiling_face:

OK. I agree with you, but can you do it if you don’t know the exact degrees?

That angle is a infinite decimal fraction… not exact

I draw a triangle with an axis and plane then loft

Here is the basic

The draft angle should be 30… Normal draft.

Here I had to play hot /cold game some Draft angels had correct length but the angle little off some the opposite
Till I reached this angle.
