extracting splines from a primitive

[Adam Trachtenberg]

I would extrude a triangle spline, make it editable, and then weld the top points to form the 3-sided pyramid. Then you can use an Atom Array to get pipes on the edges, or clone a cylinder on the pyramid using edge mode with edge scale active. Or you could select the edges of the pyramid and do a Structure>Edit Spline>Edge to Spline and then sweep the resulting spline … but that will present some twisting and junction problems.

thanks

I find it very difficult to align the three triangular spline edges, is it possible to get that perfect?

use a Cone

Top Radius 0
Bottom Radius 100
Height 141.418
Height Segments 1
Rotation segments 3

Caps – Off

Toss that into an Atom Array

Or use the N-Sided spline primitive with sides set to 3.

hmmm… Platonic Tetra too I see but where’s the fun in that 🙂
