Define Distance Problem

I have an issue relating to setting scale with control points and the distance constraint.

My control points have good "p" values and show an arbitrary distance between them when I setup a distance constraint.

The problem becomes as soon as I set a defined distance and update the alignment the whole model freaks out. It sets the calculated distance to zero and pulls all the camera poses together.

Is there something I'm doing wrong or is this a bug?

  Hi Nick,
  
  did that procedure work for you in other projects?
  Could it be a unit related issue, what kind of value are you entering?
  Did you zoom in despite the freakishly large cameras?
  That could just be an accident since RC seems to display those with random sizes.
  You can adjust them in the scene tab or disable them altogether...

  Hi Götz,
  
  Thanks for the reply.
  
  I enter 50 units as the defined distance.
  
  It's quite strange, it seems when i update the alignment it,
  1)-Sets the calculated distance to zero. Then because of this it distorts the camera positions until the two points do have zero distance between them. End result being it pulls all the cameras to the single point.
  2)-Tells me my control points have a p value of 100px. Which I'm assuming it clips at 100. Before the update alignment they were less than 1px.
  
  I re-did the whole model a few times. Setting the control points on the same scale object but from a different selection of photos. Eventually it just worked and scaled everything properly.

  Glad it did work in the end!
  Was there anything you did differently?
  Otherwise, I think that would be worth a bug report...
  
  One thing: Did you reset to factory settings?
