Hi,

You have to compile your project and all its home made dependant libraries against the same AutoCAD.Interop version libraries (i.e. the AutoCAD version you're targeting).

I'm targeting Autocad 2016 and i referenced all the dll of the 2016 version. But i'm still having a problem with Error 2 The type 'Autodesk.AutoCAD.Interop.AcadSelectionSet' is defined in an assembly that is not referenced. You must add a reference to assembly 'Autodesk.AutoCAD.Interop, Version=18.0.0.0, Culture=neutral, PublicKeyToken=eed84259d7cbf30b'. H:\CESBRON\Traceur\Automation.cs 42 9 Traceur I don't know what to change, when i replace by the Autocad 2010 assemblies it does work. A very confusing problem

You may want to provide more details on not only what versio of AutoCAD you are targeting and what versio of AutoCAD you ARE USING for your developing/debugging.

To me, it looks like you are running older version of AutoCAD (older than AutoCAD 2016) in your debugging. That is why you cannot use new version of AutoCAD COM Interop assembly. Your developing/debugging AutoCAD cannot be newer COM interop assembly. You should use the same version of Interop assembly as your running AutoCAD for your development. And yes, your application developed for the older version of AutoCAD would likely run OK with newer version of AutoCAD, as long as the CAD features used in your application are not broken by newer AutoCAD, which happens very rarely (but do happen from version to version occassionally, or intentionally).

Targeting multiple versions of AutoCAD is always risky, In general, your best bet is to use the same version as the target version for your development.

I found the solution 😄 I have to decompile the GetPointCoord.dll and DLLSelectionset.dll with JetBrains or another decompiler and change the using Autodesk.AutoCAD.Interop; using Autodesk.AutoCAD.Interop.Common with the 2016 version dll and recompile GetPointCoord.dll and DLLSelectionset.dll. After that i went in my Traceur project and referenced the two dlls. Thank you About _gile 😄 you were righ but i didn't understood at the moment.

Who is the author of the GetPointCoord.dll and DLLSelectionset.dll that you decompiled ??

I don't realy now, when i search for, i dind't foud anyone. But according to what you're saying how do i have to compile the dlls without decompiling the dlls ?

I think the point was de-compiling/disassembling somebody else's code without permission is at best frowned upon, and at worst legally actionable.

I'm part of a society and the dlls were developed by a worker of our organization don't mind everything is alright, i'm not a hacker guys :-D.
