Wine rack sketchup auto calculates size of cellar supper fast

Sketchup wine racks model automatically calculates the size of each cell to help you create a wine shelf very quickly. Especially with 45 degree cross-section wine racks, which take a long time to draw by hand. Wine racks often use a tongue-and-groove (yin and yang) wood joint, so assembly is fast and economical without screws or extra positioning jigs.

Model parameters:

• Model height, width and depth.
• Thickness and number of panels.
• Hides the border frames.
• The gap between the front and back panels makes assembly easy. This matters most for CNC cutting: a round router bit cannot machine a sharp inside corner, so every cut-out keeps a radius. The leftover inside corner radius equals half the bit diameter — a 6 mm bit leaves a 3 mm radius — which is exactly why a square tab will not seat fully unless you add the gap (or a dog-bone/fillet relief slightly larger than the tool radius) at the corner. Leave around 0.1 mm of extra clearance to absorb router runout and real plywood thickness variation.

In the model you will see panels split by seams. The panels are deliberately made up of many Components so the Dynamic Component formulas can scale each piece independently. Each sub-panel carries its own LenX/LenY so the parametric engine can resize one cell without dragging the neighbours along — that is what lets the model recompute every cell size the instant you change overall width, height or panel count. Using the Clean Dynamic tool will automatically weld those coupling plates back together; you can then edit them manually or nest the parts for cutting with the ABF plugin.

Drawing these models by hand takes a long time, and with every new project you have to redraw from scratch. In the past, laying out 45 degree cross-section wine racks in AutoCAD was difficult to keep accurate and slow, because no two panels are the same size. A 45-degree lattice is the worst case for manual work: the diagonal cells are diamonds whose edge length is not the panel pitch but the pitch divided by cos(45°) — roughly 1.41× — so a tiny rounding error compounds across the whole grid and the joints stop lining up. Driving it from a parametric Dynamic Sketchup model removes that math entirely and is the fastest solution in widespread use today. (Note: SketchUp’s Dynamic Components are still authored on the Windows desktop version — the macOS app can resize and configure a finished model but cannot edit the attribute formulas.)
