Intersect/Match causes segmented surface become curved surface

All;

This is similar to the question just posted about "Intersect/Match causes unnecessary surface fractioning". But in this case I have a curved surface which was segmented into a series of straight surfaces. After running intersect these have been changed into a single curved surface. It is not restricted to inside/outside surface types. This highly concerning for 2 reasons: 1. This is an oval building with tons of these surface. 2. This is being done to feed into CBECC-com for the detailed geometry approach, and I am unsure that CBECC-com can handle this change. I used the feature within the sketchup plugin to do the intersections & surface matching. Any thoughts? Thanks in advance - DA.
