Scale

I’m having a similar scale issue, but with orthophotos.
Workflow was as follows:

  1. Align images
  2. Mark 4 control points (each control point is picked in 4 pictures, they are points on a scale bar)
  3. Create 2 distances between these control points as constraints
  4. Update

I haven’t checked whether the actual 3D model is to scale after export, but at least when I open the ortho view in RC the “unit bar” at the top of the view is way off, and doesn’t seem to have adapted after clicking “Update”.
