Precision management in Associative GSM

When the Advanced GSM command is applied to a model and selects the Associative Mode check boxes, there are two cases concerning the precisions:

• The resulting precisions satisfy the requested ones (i.e. often the default values).
• The resulting precisions do not satisfy the requested ones, but the user accepts the result or does not take care about the warning.

This document describes how precisions are controlled when the associative Advanced GSM function is replayed when using the Rebuild Model command.

If during a Rebuild Model the resulting precisions are worse than the requested ones AND worse than the previously accepted ones then a warning is issued and the user must decide how to go further.

To go into details, let us call:

• E_req; the initial requested precisions (i.e. often the default values).
• E_old; the last accepted precisions.
• E_new; the new obtained precisions.

Then:

• If E_new < E_old No action is performed.
• If E_new > E_old

• If E_new < E_req E_old is replaced by E_new.
• If E_new > E_req A warning message is displayed.
  The actions that can be performed are the same as when a feature is failing during a Rebuild Model command (see Recovering errors when rebuilding).

E_old is replaced by E_new at the end.

Using the Rebuild button when redefining If you use the Redefine Feature command and select the Rebuild button ( ) then the reference precisions (i.e.: the previous precisions) are updated to the current ones of the redefined model.
