Inventor Developer Center

Autodesk Inventor software serves as a flexible development platform for building specialized mechanical design applications, as well as for interfacing with upstream, downstream, and enterprise applications for manufacturers. To learn more about Inventor, visit the Autodesk Inventor product center.

Inventor exposes its programming interface using a COM Automation interface. You can access this interface using most of the popular programming languages available today including Microsoft Visual C++®, VB, C#, and Delphi. Autodesk Inventor includes Microsoft’s VBA, the most popular programming environment in the world.

Tools

Inventor SDK

The Inventor SDK is installed by default when you install Inventor. It contains additional sample programs and tools to use when programming Inventor. The SDK is installed in the following location: C:\Users\Public\Documents\Autodesk\Inventor <version>\SDK

When installed, the SDK folder contains three files; DeveloperTools.msi, UserTools.msi, and SDK_Readme.htm. To access the SDK information you need to install one or both of the .msi files, that can be installed by double-clicking the .msi file in Explorer.

UserTools.msi

The UserTools.msi file contains several add-ins and standalone executables that help automate certain tasks for Inventor users that are not available in the Inventor product itself. When this component is installed, it creates the directories for the tools that include add-ins and standalone executables. The dll and exe files are installed so you can immediately use the tools without having to compile any source code. The source code for the tools is also installed which you can use as a sample and also can modify to change and extend the behaviour of these tools.

The user tools installer includes the following add-ins: DrawingTools, GeneralTools, DerivedPart_SP and AutoCustomize. It also includes the following standalone executables: ColorSchemeEditor, CopyDesign, PartNumberModifier and UpdateThreadDesignation. A UserTools subdirectory is created in the SDK folder and the programs are installed there. For more details regarding these tools, please refer to the individual "ReadMe.txt" file associated with each tool.

DeveloperTools.msi

The DeveloperTools.msi installs additional sample programs and some tools intended to help developers write applications using the Inventor API. When this component is installed, it creates the directories that contain the DeveloperTools sub folder which contains the following subfolders.

  • Docs

    This contains an object model diagram chart that can be useful in understanding the relationships between various objects. This folder also contains some guidelines to use when creating the user-interface for your Inventor programs.

  • Include

    This folder contains several header (.h) files that are primarily intended to be used by programmers using VC++. Occasionally information in these files is also useful in other circumstances.

  • References

    This folder contains a utility that is currently only used internally and is now obsolete with registry-free add-ins.

  • Samples

    This folder contains many larger programs written in several different language that demonstrate various ways to access and use Inventor's API.

  • Tools

    This folder contains two programs that are useful utilities when working with Inventor's API. The first, called EventWatcher, allows you to specify and watch certain events as they occur within Inventor. This tool is very useful when you're writing a program that will be using events within Inventor. You can use this tool to better understand the event behavior so you can know how to take advantage of it within your programs. The second, called ThumbnailView, is a small component that lets you extract thumbnail images from Inventor documents without having to go through Inventor. There's a readme and some samples that describe and show its use.

  • AutoCAD 2015-16 DotNet Wizard

    This directory no longer contains the wizards installer but now only contains a readme describing the use of the wizards. For those familiar with the previous additional step to install the add-in wizards, the separate wizards installer is no longer needed because the wizards are installed as part of the SDK installer. The wizards are used from within Visual Studio to create skeleton Inventor add-in projects.

  • Apprentice

    Autodesk Inventor Apprentice is a free COM server enabling standalone applications to have query access to Inventor Documents. Access includes assembly structure, solids topology and geometry, plus query/edit access to file references and document properties. Apprentice is installed as part of Inventor and is also installed as part of the freely available Inventor View which can be installed from here. Documentation and samples are included as part of the Inventor SDK.

  • Object Model Chart

    The Object Model Chart is very useful in understanding what objects are available and how to navigate the object hierarchy to get a desired object. The latest version can be accessed from the SDK: C:\Users\Public\Documents\Autodesk\<Inventor version>\SDK\DeveloperTools\Docs>. Click here for online version.

Porting your application from SolidWorks to Autodesk® Inventor™?

We’ve produced two guides to help those developers already working with SolidWorks, but who also want to support Autodesk Inventor.
First, we have the SolidWorks to Inventor migration guide, that highlights the similarities between the two APIs, and provides examples outlining the changes that are likely to be required to move from the SolidWorks over to the Inventor platform. The guide also highlights the key differences between the two products from a developers perspective.

  • Solidworks to Autodesk Inventor Guide - One of the differences between SolidWorks and Autodesk Inventor lies with the way graphics are manipulated by an AddIn application, so we’ve also produced a second guide that introduces Inventor’s Client Graphics system.
  • Client Graphics in Autodesk Inventor - If you’re considering migrating your application to Autodesk Inventor, please feel free to contact us if you have any questions or queries.
