Memory (RAM): Minimum 8 GB for small designs; 16 GB to 32 GB is recommended for standard work, while complex assemblies (>1,000 parts) ideally require 64 GB.

Graphics: A DirectX 11 compliant GPU with at least 1 GB VRAM (4 GB recommended for large assemblies). autodesk inventor 2020 install

    • From your Autodesk Account (products.autodesk.com) → "All Products & Services" → Find "Inventor 2020" → Download the installer for your operating system.
    • If using an educational license, download via the Autodesk Education Community.

    • Choose "Typical" (recommended) or "Custom" to exclude modules like Inventor ETO (Engineering To Order) or Content Center libraries (these can be added later).
    • Change the installation path if needed (avoid spaces in the path; e.g., D:\Autodesk\Inventor2020).

  6. Click "Install" – the process can take 20–45 minutes depending on your drives.
