Hi - I did not use match photo but imported it as an image. Actually I did what I needed to do for the client in photoshop and now re-doing it in SU to practice. I thought this is a good house to learn on.
I did not think of scaling the porch since the house was scaled. I guess any part of the house that is not flat with the siding such as the eaves and porch will need separate scaling.
If I had an angled photo and used match photo, would that solve the problem?
I would think that accurate scaling would be a problem with an angled photo too.
