Set up a volume from scratch like this:

* Use Configuration -> New...
* Use Applications -> View Estimate... to create enough cameras.
  * Just copy cameras until you have enough.
* Use Configuration -> Open to reopen the estimate.
* Acquire unknowns without using an estimate (preferably with a 3-marker
  wand).
* Use Tools -> Generate Estimate for Unlocked Cameras...
  * Save the result and update the estimate.
* Acquire knowns using estimate.
* Use Applications -> View Estimate... to make any gross changes to the cameras
  as a whole.
* Use Tools -> Align Estimate to Knowns...
  * Save the result and update the estimate.
* Calculate
  * If this is taking a long time (more than a minute), you can stop and
    get a report of where the highest error is.
  * Save the result and update the estimate.
