Tetrahedron Tool
Activate the tool, then:
-
Select or create two points in the xOy plane to obtain a regular tetrahedron with one edge defined by the two given points, and lying on the xOy plane.
or
-
Select two points having the same z-coordinate, z=c, to obtain a regular tetrahedron with one edge of the base defined by the two given points, and lying on the plane z = c. The tetrahedron can be rotated around the specified edge by dragging the third vertex of the base, created automatically.
or
-
Select two points having different z-coordinates to obtain a regular tetrahedron with the edge of one face defined by the two given points and the third vertex of the same face having as z-coordinate the average of the z-coordinates of the given points. The tetrahedron can be rotated around the specified edge by dragging the third vertex of the base, created automatically.
