Chief Architect vs TAD Designer

Chief Architect Premier is 3D design software for residential and light commercial work, including remodeling, kitchens, baths, and interiors. Drawing walls and placing architectural objects builds a 3D model and produces materials lists and construction documents such as site plans, framing plans, sections, and elevations. Materials lists can include quantities, unit and labor costs, markup, and project costs, and update as the design changes. For presentation, the software supports realistic and artistic rendering, 360-degree renderings, virtual tours, and walkthrough videos. Its 3D Library contains objects such as fixtures, appliances, millwork, furnishings, and manufacturer-specific products. It imports and exports AutoCAD DXF and DWG files, and imports OBJ, SKP, STL, and DAE. The As-Built app uses LiDAR on supported iPhones and iPads to create room models for remodeling. The trial does not expire, but saving, printing, exporting, and virtual tours are disabled. Premier costs $229 a month, billed $229/mo.

TAD Designer Lite is a space-based BIM tool for architectural design, intended to support work from early concepts through more detailed models. A design can begin with 2D shapes and gain 3D attributes later, while users query information such as areas and distances. Its built-in ARDELA language lets users make probes or add-ons for model analysis. TAD is not drafting software; 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 binary files receive a DRM signature to help protect models from misuse or copying. Support includes Discord community help, in-app contextual help, and online documentation. TAD originated in an architect's office in India in 1989. Lite is free to use; the full version requires free teamTAD Discord membership, and demo mode is available.
