importing and editing CAD 3D models to HFSS

HI,

I am tring to import and edit CAD(solid edge) 3D models to HFSS and edit those. I imported the files as .sat files and was able to successfully import it. However it won't allow me to edit 3D models that was imported. Is there anyway to do this?
(I am able to move it but not change the sizes).


Thank you
