Archicad vs TAD Designer

Archicad is building information modeling software for architects, designers, engineers, and other AEC professionals working on building projects. Its tools cover mass modeling, sketches, optioneering, quantity take-offs, building elements, and custom components. The software turns 3D models into coordinated drawings with real-time and automated annotation updates, and supports openBIM workflows through IFC, BCF, and IDS. BIMcloud can host a centralized model with live updates and notifications. Studio includes local teamworking with BIMcloud Basic; Collaborate adds MEP modeling and Graphisoft-hosted BIMcloud for global Teamwork. Visualization options include photorealistic visuals, fly-throughs, animations, and a cloud-powered AI Visualizer. Archicad runs on macOS and Windows, with compatible file formats and Teamwork between versions. Studio costs $201 a month, billed with an upfront $2,414 + tax for a one-year subscription per seat. Collaborate costs $237 a month, with $2,840 + tax upfront for a one-year term per seat. Eligible students and educators can use a free educational license for non-commercial work; EDU files carry an irremovable watermark.

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.
