Hi, Some help with a small problem would be greatly appreciated.

This is a product we have been manufacturing for years, it was originally surface modeled in catia, so we have ample step files and such, but nothing that we can acutally edit.

now we are trying to reduce the width but there are a couple of issues I am having, first up is creating a fillet, please see the attached photos to see what i am trying to reverse engineer, and where I have managed to get to... any suggestions at all would be massively appreciated!

thanks.

Simon
