TAD Designer
What TAD Designer is
TAD Designer Lite is a space-based BIM tool for architectural design, intended for work from early concepts onward. Designers can develop loose ideas into more detailed models, starting with 2D shapes and adding 3D attributes later. During the process, users can query design information such as areas and distances. The built-in ARDELA language lets users create probes or add-ons for model analysis. TAD is not drafting software: the maker says designs can be exported to CAD and 3D software, including RenderMan-compatible renderers and POV-Ray. Listed supported formats include VRML 2, Virtualight and RenderMan. The maker describes Lite as intended for small and medium architectural offices, especially in developing countries. Work is saved on the user's computer or LAN. The maker says TAD adds a DRM signature to binary files to help protect models from misuse or copying. The product is free to use; the full version requires free teamTAD Discord membership, and demo mode is available. Support options include Discord community support, in-app contextual help and online documentation. It runs on Windows, with Mac and Linux support via WINE.
