Autodesk Inventor Nesting
Inventor Nesting is an advanced sheet metal nesting software that works directly inside Autodesk Inventor. It helps manufacturers optimize material usage and reduce scrap by automating the arrangement of flat parts on metal, wood, or composite sheets.
Integrated Nesting for Sheet Metal Design
Inventor Nesting enables you to generate optimized nesting layouts from Inventor part files, assemblies, or DXF profiles. It integrates seamlessly with Inventor’s sheet metal workflows, providing a smooth transition from design to fabrication.
Material Efficiency and Cost Savings
Reduce material waste with intelligent nesting algorithms that account for part shape, quantity, grain direction, and sheet size. Analyze nesting efficiency, material utilization, and sheet count with detailed, customizable reports.
Seamless Workflow to CAM
Export nests as DXF files for use in laser, plasma, waterjet, or CNC routing machines. For Inventor CAM users, nests can be directly prepared for toolpath programming, allowing end-to-end design-to-manufacturing automation.
Key Features
- Fully integrated with Autodesk Inventor
- Automatic nesting of multiple flat parts and sheet sizes
- Support for material constraints, grain direction, and part quantities
- Detailed nesting reports: efficiency, waste %, sheet count
- Export to DXF and interoperability with Inventor CAM
- Ideal for sheet metal, wood, composite, and plastic cutting
Who Uses Inventor Nesting?
Inventor Nesting is ideal for sheet metal fabricators, furniture and cabinet makers, industrial equipment manufacturers, and any production facility that requires high-volume part cutting from flat materials. It helps reduce waste, lower costs, and streamline the manufacturing workflow.
⚠️ IMPORTANT:
Integrated Utility: Inventor Nesting is not a standalone application. It functions as an add-in for Autodesk Inventor. You must have the corresponding version of Inventor installed (usually via the Product Design & Manufacturing Collection).
Windows Only: Because Autodesk Inventor is Windows-only, Inventor Nesting is also Windows Only.
Calculation Intensive: Nesting algorithms (calculating the most efficient layout of shapes on a sheet) are mathematically complex. While standard Inventor requires a good GPU, Nesting requires a Strong CPU.

💡 Performance Advice for Inventor Nesting Users
RAM is the Critical Bottleneck:
To create a nest, the software must open every single .ipt (part) file in the background.
If you try to nest an assembly with 500 unique sheet metal parts, Inventor must load all 500 parts into RAM.
Recommendation: If you nest large assemblies, 64 GB RAM is highly recommended. 16 GB is often insufficient.
CPU Core Usage:
Unlike standard modeling (which is single-threaded), the Nesting Utility includes a Multi-Core Nesting Engine.
It can calculate multiple sheet layouts (studies) in parallel. A CPU with 8+ Cores (Intel Core i7/i9 or Ryzen 7/9) will complete a complex nesting study much faster than a quad-core CPU.
DXF Exporting:
A common workflow is exporting the nested sheets to DXF for CNC cutters.
This process writes data to the disk. Using a fast NVMe SSD significantly speeds up the "Export to DXF" process.
Mac Users:
Not Supported: Inventor Nesting cannot run on macOS.
Parallels Desktop: It is possible to run this on a Mac via Parallels, but due to the high RAM requirements of loading multiple parts, you must allocate at least 16GB–24GB of RAM just to the Virtual Machine. This requires a Mac with at least 32GB+ of Unified Memory.
