Allplan vs TAD Designer

ALLPLAN is interdisciplinary BIM software for architecture, engineering and construction, supporting work from design through construction. Its workflows bring together building and infrastructure modeling, detailing, fabrication and construction planning. It covers architecture, structural and MEP engineering, civil and bridge engineering, precast detailing and construction site planning. Cloud services support project and office teamwork, coordination, and distribution of drawings and plans. For exchanging data, it supports IFC 2x3 and IFC 4, DWG/DXF, PDF, SketchUp and Rhino. Programming options include Python parametric PythonParts, Visual Scripting and the NOI interface for add-ons. The four listed plans are Basic at €123 a month, Concept at €210 a month, Professional at €263 a month and Ultimate at €353 a month. A 14-day trial is available, but there is no free plan.

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.
