① Getting Started — Build Your First Rack

Open mr.sangdogagu.kr and the Start 3D Build window appears first. Set just the basic size here — everything else can be changed freely on the 3D canvas.

Choose product and color

Product — choose Monster Rack or Rack Plus.
Frame — Ivory or Black.
Dual-color shelf — Wood or White.

Monster Rack Easy Builder Start 3D Build window — product, frame, dual-color shelf, and size sliders — The start window. Pick product, color, and size, then press Create.

Set the size

Use the sliders to set Width × Depth × Height (mm) and the number of tiers. For example, choosing W800 × D400 × H1800 creates a 3-tier rack by default. You can fine-tune the exact dimensions anytime, so an approximate size is fine to start.

Create

Press Create and your first rack appears on the 3D canvas. The layout works like this.

Monster Rack Easy Builder 3D canvas — rack body, dimension labels, edit panel, top view — The 3D canvas. Your rack sits in the center, the edit panel at the bottom, and the top-view layout in the lower right.

Top — Options · Quote · Order buttons.
Bottom edit panel — change the selected module's width, depth, height, and shelves.
Left tools — fullscreen · 2D view · show dimensions · undo · help.
Lower-right top view — the layout seen from above and the overall size.

💡 Drag with the mouse to rotate the view, and click empty space to deselect. If you make a mistake, press Undo at the top.
