| Name | Description | |
|---|---|---|
|     | CantKeepConstraintsToBars |  The constraints between the coupler and the two connected bars are no longer satisfied. Post error to delete the coupler.  | 
|     | CouplerRequiredRemoveFromGroup |  The coupler is invalid in group.  |

|     | DisconnectElements |  Disconnect the coupler from the connected bar.  | 
|     | DistanceBetweenBarsError |  This is used to post error. The distance between the connected ends of the bars exceeds 10 bar diameters.  | 
|     | DistanceBetweenBarsWarning |  This is used to post warning. The distance between the connected ends of the bars exceeds 10 bar diameters.  | 
|     | EngagementBiggerThanLengthError |  This is used to post error. The sum of bar engagements is greater than the total coupler length.  | 
|     | EngagementBiggerThanLengthWarning |  This is used to post warning. The sum of bar engagements is greater than the total coupler length.  | 
|     | LengthParameterError |  This is used to post error. The "Total Length" parameter must be set to a strictly positive value.  | 
|     | LengthParameterWarning |  This is used to post warning. The "Total Length" parameter must be set to a strictly positive value.  | 
|     | MainEngagementParameterError |  This is used to post error. "Bar Engagement 1" has an incorrect value.  | 
|     | MainEngagementParameterWarning |  This is used to post warning. "Bar Engagement 1" has an incorrect value.  | 
|     | NoBarSizeError |  This is used to post error. At least Bar Size 1 or Bar Size 2 should have another value than "None".  | 
|     | NoBarSizeWarning |  This is used to post warning. At least Bar Size 1 or Bar Size 2 should have a value other than "None".  | 
|     | NoTypeParamsDefinedWarning |  The parameters of the default type have no values.  | 
|     | SecondaryEngagementParameterError |  This is used to post error. "Bar Engagement 2" has an incorrect value.  | 
|     | SecondaryEngagementParameterWarning |  This is used to post warning. "Bar Engagement 2" has an incorrect value.  | 
|     | WidthParameterError |  This is used to post error.The "External Diameter" parameter must be set to a strictly positive value.  | 
|     | WidthParameterWarning |  This is used to post warning. The "External Diameter" parameter must be set to a strictly positive value.  |
