Converting to step - Inconsistent spline curve

Hey, I havwe been converting to step for me and myFiberglass/Design people to go back and forth, they are using pro eand catia...anyway I have neverhad a problem till today......

Sw will not save my model to step, I get error message"Inconsistent spline curve" which I have ruled as being part of themodel that I was sent this morning from my fiberglass people and Iopened from a step file then saved the necessary peices to mymachine model in sw parts....

Anyone know what I should do??? I cann't change theirwork....Surfaces and all that bs,SolidworksImport export
