Draw

Draw makes custom shapes. Open it with the Draw mode switch in the Add tab. The workspace shows a grid of dots. Tap dots to trace the 2D outline you want. Tap the first dot to close the line (at least three dots). Lines can’t cross or touch. A finger on the workspace shows the dot a tap would select; hold still for a moment to aim, slide to the dot you want, and lift to put it down.

Dots sets the dot spacing: 1 (default), ½, or ¼ block. It keeps your choice until you close the app, and it is hidden once the loop is closed. A coarser spacing can’t be selected while placed dots are off its grid.

Flat or solid

Closing the loop shows the Flat / Solid toggle. Flat adds a flat 2D shape. Solid adds a solid shape and shows Height (starts at 1 unit).

Select Build it to add the shape. It is its own part, and the tab returns to Place mode.

Fixing a line

While tracing, select ↩ Undo dot to remove the last dot, or ✕ Start over to clear the line. On a closed loop, ↩ Undo dot opens it again. The Undo button also undoes dots while you trace. Nothing is added until you select Build it.

Drawn shapes work like the basic shapes. Move, size, and turn them in Details .
