nTop · New York City, United States · founded 2015
What it is
nTop is an engineering design platform for creating parametric geometry and exploring design variants. Its implicit modeling represents geometry mathematically, which the company says helps models stay stable through large parameter changes. Users can automate design logic across thousands of variants, using desktop or distributed cloud compute. The platform also uses GPU compute and machine learning to shorten simulation feedback cycles. It supports assembly and surface modeling and imports CAD, mesh, CAE, and other formats, including STEP, Parasolid, CATIA V5, Creo, SolidWorks, STL, and ANSYS files. Listed exports include STEP, Parasolid, STL, and 3MF. The interactive desktop application supports Windows 11 and connects to cloud services for license authentication and software updates; usage data may be sent according to user preference. nTop Automate also supports Red Hat Enterprise Linux 8.9. System requirements specify at least 64 GB RAM and an NVIDIA GPU with Volta architecture or newer and 8 GB VRAM. Commercial license pricing is available on request. Students, educators, and academic researchers can apply for a free non-commercial version. nTop was founded in 2015 and is headquartered in New York City.
