Hi Michael,

I have checked with SW Interconnect function and when I switch to this mode where it keeps the step file as a reference file which you can re edit whether it comes out of MoiV3 or MoiV4 the parts names are lost - will do some more research on this I use this heavily in my work flow - I use MOI as a concept tool and general shaping do final preparation in SW then save as STEP for sharing with other SW users.
