Tekla 21.1 System Requirements [work] -

To run Tekla Structures 21.1 efficiently, your system needs to handle complex 3D modeling and detailing. While there are "minimum" specs, professionals generally need "recommended" hardware to avoid lag in large models . Core System Requirements

Warning: Do not use the Minimum specs for production work. The viewport will be laggy, and numbering will take several minutes. tekla 21.1 system requirements

My practical advice:

• Windows 10 (64-bit) - version 1903 or later
• Windows 11 (64-bit)

🎮 GRAPHICS CARD

• Good: NVIDIA GeForce RTX 3060 (gaming cards work well).
• Better: NVIDIA Quadro RTX 4000 (certified drivers; less crashing in large assemblies).
• Bad: Intel UHD Graphics 620 (no dedicated VRAM). You will experience “redraw lag” when zooming.
• Avoid: AMD Radeon RX series (historically driver issues with Tekla 21.1’s DirectX implementation).
