Run the solver

You can run the solver automatically or in several interactive steps. Both methods use the same algorithm, but you have more control running in interactive steps.

One automatic process: This is the simplest method, because the solver runs through all steps at once.
Interactive steps: With this method, you control which step to run and you may repeat steps to see the outcome of improvements you make.

To run the solver in one automatic process

Open the Solve control panel.
Verify the frame range is correct; change it if needed.
Click the Solve button under the Root Frame heading.
When the solution is complete, it appears in the solution list named solution_rf.
Click the As Object checkbox if you want to switch the solution to object movement around a fixed camera.
Evaluate the solution to look for problems (see Evaluate a solution).
If you find problems, you can run the solver again, but you can probably save time running the solver in steps.
NoteWhenever you want the solver to produce a brand new guess, select initial1 before you restart the solver.

To run the solver in interactive steps

Follow these guidelines:
- Follow the general order: Start, Continue (if you want Start to run longer), Refine, Finish, and Register (if you add or change survey constraints). For details on each step, see Root Frame step descriptions.
- Between each step, evaluate the solution and make any needed improvements.
- Repeat steps as needed to incorporate changes.
- Click Register at any time to see the effect of survey constraints on your solution as a whole.
- Keep notes on the changes you made before running each step. Because you typically repeat steps, knowing what you tried, such as adding points or constraints, will help you isolate problems later.
- Make sure the last solution is selected before running the next step. The solver uses the selected solution as a starting point. For example, select guess# (where # is the number of the guess) before clicking Refine.

Root Frame step descriptions

Use this table if you are not sure what step to run.

Step	Purpose	When to Run
Start	Creates an initial guess.	At the beginning and whenever you need a new guess. Make improvements and repeat until you get a close solution.
Continue	Optional step that continues guessing where Start left off.	Immediately after Start, if you want the solver to consider other possibilities.
Refine	Recommended step that improves the best guess.	When you want to refine a close guess. Make improvements and repeat until you get an accurate solution.
Finish	Required step that applies the solution to all frames.	Once, when you get an accurate refined solution.
Register	Registers the whole solution to survey constraints.	Whenever you want to see the effect of survey constraints on your solution as a whole. (If you want the constraints to affect the shape of the solution, run Start or Refine.)
