file conversion

ok i’ve been trying all day, my boss needs this immediately

how do i convert a .jpeg to a .x_t file? none of these shit software programs like UG and rhino can do it properly…nothing comes out 3D

I’ve got ashlar Vellum 3D on Mac.
I’ll try it on that.

What’s a .x_t file? I’ve never heard of it.

.jpeg? 3D? trying to create a height map?
