think3 Technical Migration Advisory

File Translation RiskModerate Risk

Legacy drawing databases (.dwg, .rvt, native mechanical files) are highly complex. Vetted alternatives translate raw geometries accurately, but active parametric assembly links may need physical verification.

Shortcut Muscle MemoryHigh Affinity

Industry standard alternatives fully support standard keyboard alias tables (.pgp command strings) allowing veteran draftspeople to maintain full drafting speed on day one.

LISP & Automation MacrosVerification Advised

If your workflow relies heavily on native custom scripts or proprietary LISP plugins, always verify whether the chosen alternative supports active LISP code execution before moving.

Advisory:Establish a dual-license grace period of 30 days. Export intricate models into neutral standard STEP/DXF structures to verify actual dimension preservation limits.
