Include 3D mechanical in your modelling workflow

Autodesk Inventor LT Suite offers part-level 3D parametric modelling, multi-CAD translation, automated DWG drawing views and other 3D mechanical CAD abilities.

Part modelling & MultiCAD

Inventor LT shares many of Inventor’s powerful tools, but keeps its primary focus on part modelling. An affordable solution for mechanical design professionals.

Inventor LT overview

3D parametric modelling, multi-CAD translation, automated DWG drawing views and other 3D mechanical CAD abilities.

Free-form tools

Create visually compelling designs using flexible modelling techniques.

Direct Edit

Easy push/pull controls enable you to quickly move, rotate, resize or scale features from native or imported geometry.

3D CAD data import/export

Improve collaboration workflows with interoperability in multiCAD environments.

DWG Interoperability

Insert associative DWG geometry, manage layer visibility and create 3D models of 2D layouts.

Parametric modelling

Intuitively model parts using parametric modelling tools in Inventor LT.


Export your models to 3D PDF for a great collaborative experience.

Addictive manufacturing

Use the 3D Print Environment for additive manufacturing.

Network license manager supports Windows Server® 2016, 2012, 2012 R2, 2008 R2 and the operating systems listed above.


Full local install of Microsoft® Excel 2016 or later for workflows that create and edit spreadsheets. Inventor workflows that read or export spreadsheet data do not require Microsoft® Excel.

Office 365 subscribers must ensure they have a local installation of Microsoft Excel.

Windows Excel Starter®, OpenOffice®, and browser-based Office 365 applications are not supported.


Google Chrome or equivalent

.NET Framework

.NET Framework Version 4.8 or later. Windows Updates enabled for installation.


  1. Autodesk® Inventor LTTM is optimized to take advantage of the SSE2 extended instruction sets supported on Pentium 4, AMD Athlon 64, and AMD Opteron processors. Inventor LTTM will not install on computers that do not support SSE2. Several utilities are available on the Internet that report CPUID including supported instructions sets.
  2. Autodesk recommends settings which allow Microsoft Windows to manage virtual memory as needed. There should always be at least twice as much free hard disk space as system memory (RAM).
