The constraints can be set before you create a runner system so that all sections have the same constraints, or they can be set after you create a runner system so that different constraints for different sections can be specified. Three constraint options are available.
The dimensions can be set to the following for each runner section:
- Free - No restriction on minimum or maximum size.
- Fixed - No change to size permitted.
- Range - Only changes within a specific minimum and maximum range permitted.
Note: The gates and sprue cannot be constrained where optimization occurs.
