Grid size changes the smoothness of gridded surfaces and significantly affects the speed of model regeneration.
It's generally recommended that:
•large values (low resolution) are recommended while developing models
•small values (high resolution) are only used for the generation of outputs (i.e. model files and drawings)
Grid size can be defined as any value down to a minimum of 1 drawing unit (i.e. 1m), however grid size is also dependent on the size of the data limit.
If the data limit is large and grid size is small, the grid size may be automatically increased to ensure that sufficient computational capacity is maintained.
Below are some examples of various values showing the affect on gridded surface generation:
