Hi Evan,
Not sure what you mean here. Cannot view the OPS_ACH_ARC_RAIL_V5.eprt (I
get an error) but have had a quick look at the JPGs.
Does not seem overly complex to me but yes, from these pictures, I would be
approaching it with surface rather than solid modelling. I suggest anybody
competent in surfacing will not find it much challenge; you will not need an
expert. However I will add a rider that the devil is always in the detail
and there may be something I cannot see from the images that can trip you
up.
Think of extruded surfaces, variable section sweeps, sketched datum curves
and the like.
If you have a part and the reverse engineering module you can get to it from
scanned data 🙂
Not sure if this helps at all.
