Service

Lightchalk is a technical tool for visualizing, editing and projecting construction layouts and project data.

Professional verification

Lightchalk does not replace an architect, engineer, licensed designer, inspection professional or other qualified specialist. Dimensions, calibration, positions and technical decisions must be physically verified before construction work is carried out.

Availability

Intellectual property

The Lightchalk software, interfaces, data model, catalogue and technical rules are protected by applicable intellectual-property laws. Customers retain ownership of the project data and files they upload, subject to rights necessary to operate the service.
