Running an enterprise CAD utility natively on newer operating systems requires strict attention to computing components and environmental settings. System Requirements Minimum Specification Recommended Specification Intel Core i5 / AMD Ryzen 5 Modern Intel Core i7/i9 or AMD Ryzen 7/9 (>5.0 GHz) Graphics (GPU) Intel Integrated HD Graphics Dedicated NVIDIA RTX / Quadro or AMD Radeon Pro System RAM 16 GB to 32 GB for large assemblies Storage 10 GB free space on HDD Solid State Drive (SSD) via NVMe Modern Operating System Support
The native 64-bit architecture removes the restrictive 4GB RAM threshold found in older 32-bit iterations. This enables the system to allocate massive segments of physical memory to render large assembly trees, such as full automotive chassis or aircraft structural frames.
