Challenge

[Chayanne]

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!

you mean as in the picture?

[MrJack88]

You noticed a problem haven’t you ?

[JST]

If the peak all 90 deg…its easy

@Chayanne

[Chayanne]

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

[Chayanne]

Keep trying

[JST]

But it have 60 deg on the sides…

I made it a long time ago

Tetrahedron in Shapr3D

[JST]

Its called : tetrahedron

[Chayanne]

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

[MrJack88]

Man some wrong with angles

But I got it

[Chayanne]

Can you show the steps?

[MrJack88]

There you go

Here is the sketch as well

[Chayanne]

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

[JST]

That angle is a infinite decimal fraction… not exact

[JST]

I draw a triangle with an axis and plane then loft

Here is the basic

[MrJack88]

@Chayanne
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.

Congratulations! This is the easiest way
