This is the way I "Scaled" the part, which is similar to Torfinn's method.
I selected the part, activated "Keep Aspect Ratio", then Tabbed over to the Size X field and increased the size by 0.1mm. Enter. I got a message that this could affect the PartTree, but continued. The new part is just at the size specified. I didn't do anything with the Profile that was out of view.
