Can I Draw On An Existing Photo In Chief Architect?

[MPDesign]

I think your better to draw the house from the picture, then add the elements you desire. Then as you said render with picture as a background.
If you have the software make a mask layer for a foreground.

It didn't work all that well....

I agree that it would probably be better to create a chief model and go from there
