In today's world the desire for 3D renderings to help architects is becoming increasingly popular. The ability to show a client how the house will look before construction even starts is an invaluable tool. Not just to make sure that the client likes the house, but also to give them something to grasp. A floor plan and an elevation can be good to show them an idea, but how the building will look on the inside is harder to convey. And ultimately the inside is what the client really wants.
Now with 3D rendering we can show the clients every aspect of their home. Showing them a rendering is sort of like a trial run, to make sure it's what they really want. And the greatest thing is that the clients can experiment with different designs without arranging multiple meetings. All options can be visualized right on the spot!
