extract inventor developer tools without Visual Studio installed

in this article will show how to extract the data from an msi (developer tools.msi) to at custom folder without having the dependencies installed.

If you have Visual Studio 2019 or above you cannot install the developer.msi. It will throw an exception that you need to install Visual Studio 2017.

Thanks to Mika who pointed me in the right direction it is possible to get the tools out of the msi.

  1. open command line
  2. (msiexec /a „C:\Users\Public\Documents\Autodesk\Inventor 2019\SDK\developertools.msi“ TargetDir=C:\Temp\dt) doc link

unit testing with inventor api

unit test are annoying and time consuming. ist not fun at all, and the customer does not see any value in tests…..

i hear this all the time, and at some point in my tech career i also belived this. Then i wrote my first test an found a bug. At this point lightbulds started to glow and i realised that i woul not found the bug bymyself.

In the worst case the customer would have found the bug :C

As we all know writing tests makes our software more stable and maintainability will be increased.

unit tests with the inventor api

AutoCad Inventor makes it very difficult to write testable code. At some point i thought that i am lucky. The api is completly build by interfaces.

For examle the Application and the documents


getting started with the Inventor api


on this site i will talk about how you can start implementing your own add in for the 3D CAD Software Inventor. This will explain how to implement a basic addin without any functionality.

Inventor provides a lot of functionality , but sometimes you want to improve these features or you want to add own features. You can achive this with the powerfull Inventor Api.

The used example can be found on GitHub.


  • Inventor installed (theoreticly you do not need Inventor installed. You just need the refernce to the ‚Autodesk.Inventor.Interop‘ assembly)
  • optional: Inventor SDk installed
