See it to scale

See it to scale: the case builder's Army Green Day case beside a coffee mug on a walnut workbench, its width, depth and height marked

The case builder could always show you a case in 3D. What it couldn't show you was how big it was. A Day is four squares by five, which tells you nothing until you know how big a square is, and on a screen a Pocket and a Range look about the same size. You'd have to take our word for it, or find a ruler.

So the builder now answers the question three ways.

A mug

A 12 oz coffee mug now stands to the left of every case. It's always there, and it's the same mug that sits beside our cases in our other pictures. Nobody needs a ruler to read a mug. The Pocket is about as wide as it. The Day is about two and a half mugs across, and the Range about three and a half. With the lid shut, every case stands a little over half as tall as the mug.

A Sizes button

Press Sizes and the builder draws dimension lines on the case, the way a shop drawing would: the width along the front, the depth down the right side, and the height at the back corner. They're measured from the case model itself with the lid shut, so they're the outside of the case. The Day reads 8.6 by 7.4 inches, and 2.1 inches tall.

With Sizes on, click a tray and it shows its own size too. The view frames the mug and the dimension lines whether they're showing or not, so pressing Sizes never makes the picture jump. And the panel now says how big one grid square is: about the width of a golf ball.

A bench to stand it on

The first version stood the case on a small board of birch plywood, cut to fit. You could see every edge of it, and it looked more like a cutting board than a workbench. A case like this doesn't live in a kitchen.

So now it stands near the front edge of a six-foot walnut workbench, with a 2x4 apron and 4x4 legs. The rest of the bench runs out of the frame, the way a real one would. Behind it is pegboard on a painted wall, with a hammer, screwdrivers, wrenches, pliers, a tape and a level hung low enough for the camera to catch. Under it all is a dark concrete floor.

The Range on the bench: Army Beige case, Army Green lid, four Bay bins filling all 42 squares.

None of it costs you a download. The page draws the wood, the pegboard and the concrete itself, and the tools are a few hundred triangles of plain boxes and cylinders. The builder fetches nothing it didn't fetch before.

Light from the front

One fix came along with the bench. The builder's main light used to sit in one fixed spot. The Day faces one way, and the Pocket and the Range face another, so those two were lit from behind, with the side you open in their own shadow. Now the light comes from each case's own front left.

Try it

The case builder is under "Build" in the menu. Pick a case, turn on Sizes, and look at it next to the mug. When it looks right, the case and everything in it go in your cart together.
