can't get started (without you)

Click on the kitchen and you can rotate and zoom in on it. Sketchfab is like Pinterest for 3D modelers to share manipulable, virtual objects with anyone who has a browser. But the object still has to be modeled! How to get started? Temple Grandin makes a case for tactile involvement in design:

"One of the things I’ve noticed, been involved in my industry designing things for over 25 years. The people who are really good at drafting on the computer are the people who were good at drafting by hand. People coming in now doing computer-aided drawing are doing terrible drawings, they make lots of errors, they leave out perceptual detail, they don’t see it. The errors made in their drawings are the errors that the very worst students in my design class make; these are the students that have no visualization capability. I don’t think the mouse is hooked up to the brain like the hand is. You don’t make some of these mistakes if you actually draw the thing by hand. Let’s say for example, you’re drawing a cattle stockyard, you’ve got a whole lot of gates in it; one draftsman I saw, using computer-aided drawing, had 25-foot gates built in it. You can’t have a 25-ft. long gate; the leverage will make it come off the hinges. Now if you take a compass, you’ll see that you can’t do it. I’m seeing more and more mistakes being made in construction because it’s getting too abstract.

I visited with Irene Pepperberg, whose parrot can learn categories. To learn them, he had to manipulate the objects; looking wasn’t enough for him to understand. I can really relate to that. Touching gives an understanding you don’t get just by looking." 2000 interview with Temple Grandin in the Harvard BRAIN, bold emphasis mine. 
Drawing by hand and rough modeling with cardboard and clay are excellent ways to strengthen one's visualization capacity.
