Knife Projection in Blender 2.49

I have a little problem with a project I work on:

I want to cut some triangles (and other shaped) out of a tetraeder.
Following the current descriptions for “knife project” made me:

  • create the tetraeder (works fine)
  • create a circle (with 3 vertex) and bring it into position
  • select both
  • switch to edit
    ** Now I am supposed to click “knife project” in the mesh tools, but… 2.49 does not have that.

Is there some workaround? Or some other trick I miss and can’t find in Blender 1.49?

To illustrate, my problem in pictures:

The knife project tool appeared years after blender 2.49 was a dim and distant memory. Why are you using it ?

You can use face snapping to snap a shape onto the object then manually edit the object with knife tool.
Or use the boolean modifier to cut one shape into another.
Basically you’ve got more manual editing to do that if you used the correct tools

Solved by running 2 variants of Blender now…
