Axis-end frame connection is related to an end port that is different from the supporting member end port. Change connection to unsupported and then re-select the supporting member. - Intergraph Smart 3D - Help - Hexagon

Meaning: The input end port of the supporting member does not match the related end port of the axis-end connection, resulting in inconsistent relationships. This is an internal software failure where the axis-end connection was defined incorrectly.

Recovery:

1. Select the frame connection in error.

2. Select By Rule from the Connection box in the Properties View.

3. Redefine the end location of the member.
