The same cadaclysm_blacksmith module the SDK ships, running in your browser. Shift+Enter runs a cell, Tab completes from the live kernel; the last expression, if it is a solid or a profile, is drawn, and so is anything passed to show(); a profile is drawn as its outline, on the XY plane. A last expression that is a list or tuple of them draws them all in one view, as show(*items) would. solid.coloured("#c8a060") is the solid coloured, solid.coloured(colour, face=i) one face of it, and what is made from it keeps the colours. Copy the script and it runs unchanged next to the library.
This page needs WebGL2, module workers and WebAssembly. The forge may still work here.
