Draw Lab

Draw lines. Export HPGL + SVG.

Make plotter-safe line art under real hardware constraints. Rev4.5 adds cache-busted drawing assets, visible-viewport mapping, and manual pointer calibration for stubborn curved/high-DPI screen offsets. Lock board still helps keep the drawing surface stable.

Rev4.5 maps pointer coordinates to the visible SVG viewport and supports manual X/Y calibration. If the browser itself is zoomed, set zoom to 100% first.
