From a material calculation to a project list
The first working site brings material calculators, scale drawings and a saved project list into one place.
Try a material calculator
Measure, draw, plan
The early collection includes concrete block and slab, rebar, tile, board foot, deck, fence, roof, gravel, sand, sod, asphalt and retaining wall tools. U.S. units come first, with metric options where supported. Calculations include diagrams, editable assumptions and source references.
The drawing tools support irregular outlines. DXF import reads supported closed contours and lets you choose the outline and units; DWG files are not supported.
Keep related materials together
Add results to a project list, rename items and combine compatible material totals. CSV, JSON backups and printable reports make the list portable.
The list is stored in your browser, without an account. Keep a JSON backup if you need to move it to another browser or device.
An early visual record
The screenshot below preserves the original block-calculator prototype. It predates the current logo, custom controls and cool-toned interface; it is an archive image, not the current calculator.
This milestone was documented on October 20, 2026 and added to the public history on October 22, 2026. Its version was assigned retrospectively. Screenshots show the development state at the time. About this alpha history.
