Autodesk Inventor Interop reference older version

bradeneuropeArthur — Fri, 19 Jan 2018 20:18:28 GMT

Hi,

My question is how can I program in vb.net for an older version of inventor with a newer version inventor.

I want to create a add in referenced to the Autodesk.Inventor.Interop.dll inventor 2017, but I am having installed inventor 2018.

How can I do that?

Most of the old dll are installed at: C:\Windows\Microsoft.NET\assembly\GAC_MSIL\Autodesk.Inventor.Interop

Delete reference to 2018 and add reference to another dll.

Did not know that.
Now I can program also for older releases.

I maintain few version for my addin: 2015, 2017 and 2018.

Open the project, change the reference dll, compiled file location and save it with a new file name.

If there is changes then I'll need to compile it 3 time.

I believe there is better, faster way to do this but I haven't figure it out yet.

A batch compile script and a installer to copy would be great.

I think I can set my folder to be the same as the ApplicationPlugins folder.

My 2012 addin works in 2015 and up. UI is Ribbon only in newer version. Basically I use the same VS template.

Even Examples in Inventor Help are the same over the year.

Only different is new features in newer versions. The What's New section in each year's help will have new API features. As long as you don't use new features, the addin will run in older version.

You'll have error when compile if you use any newer functions.

In the .addin file you need to set the version:

No, you don't.

As long as the addin is compile with the correct reference it'll run.

Inventor is backward compatible. 2016 addin will run in 2018. Unless it try to modify Library location

2017 installed 4 old interop: 17-20. So you should be good with 2016 (20.0).
