Who says clients don't pay for modeling?

So then you show them how a 2D drawing does not reveal things like a dark entry set back 24' from the front of the house with opposing overhangs that leave less than three feet of daylight overhead.

The 3D model reveals all this, so we show them how to avoid the problem by bringing the entry forward, raising it to bring it light, etc. Keep in mind that you are looking at a house that will sell for over $600,000 in the fantasy world of Southern California and in a fair to average neighborhood.

So I would submit to you that you do not sell 3D modeling to your clients. Use 3D modeling to sell you. With 3D, what you see is what you get.
