Member part cutLength is zero.
A member part has a cut length less than or equal to zero.
The member part or system was manipulated such that the part axis is zero in length. This problem could have been due to a direct manipulation of the end of the member part, making the start and end point coincident, or as a result of an indirect modification that forced the ends of the member part to be coincident.
What You Should Do
Remove the member part, or move the part such that its ends are no longer coincident.
Open the model.
Locate the offending member part, and move or modify it such that its end points are no longer coincident.
