Put a ball halfway between two points

Two points of the Lumen frame are given: the bottom bracket A = (0, 0.3, 0) and the head tube's bottom B = (0.47, 0.7, 0).

Add a small ball named midpoint exactly halfway between them. Do not type the answer: work it out from A and B with vector methods.

What Check tests

  1. A mesh named midpoint exists
  2. It is at (0.235, 0.5, 0)
  3. A and B were not moved
