TumblerForge — Layers & Editing

• Can I recolor parts of my design to keep track of layers?

  Yes — the color swatch in the top toolbar applies any of 12 layer colors to the selection, including everything inside a group. Color is a working aid: engraving only cares about shape, and the 3D preview shows every design as engraved metal regardless of its canvas color.

• How do I group and ungroup objects?

  Select multiple objects (drag a box or shift-click) and click Group in the top toolbar; a group moves and scales as one. Ungroup splits it back apart. Grouping is temporary glue — for permanent single-shape behavior, use Make compound instead.

• How do I resize without distorting my design?

  The lock icon in the top toolbar keeps the aspect ratio tied — change W and H follows. Unlock it to stretch one axis on purpose. Corner handles on the canvas always scale proportionally.

• How do layers work?

  Every object is a layer, listed top-first in the Layers panel on the right. Click a row to select it (even if it's buried under other art), drag or use the arrows to reorder, and click the eye to hide a layer while you work. New objects are always created on top.

• What does Make compound do, and when do I need it?

  It merges a multi-part SVG into one single path — one layer, one click to select, holes preserved. Uploaded SVGs often arrive as dozens of separate pieces; compounding them first makes boolean operations (subtract, weld) fast and predictable. Release splits a compound back into its parts.
