SimSolid STEP File Import Randomly Skews Parts

I have had this issue with SimSolid since I started using the software almost a year ago. Whenever I create my model in HyperWorks, export as a STP file and import it into SimSolid I always have 1 lifting lug which loads without a problem, then the other 3 are randomly skewed and unusable. I've tried remodelling the parts, translating duplicates, organising into different components, adding different notches into the 4 lugs so that they are all dissimilar, nothing works. It's far too time consuming going through all the above steps over and over again until eventually the lugs are close enough to original design for analysis.

Please assist.
