I would like to write my own addin to extend the functionality of the PTC modeler (artisan studio v7.0). However, I have not been able to find any documentation in this regard.
Could you please point me at documents where this information might be described.
In an Artisan Studio 7.0 installation there should be a document "Automation Interface.pdf" on your system in the equivalent folder to:
\Program Files\Artisan Software Tools\Artisan Real-time Studio\System\PrintableDocs\Addins
on your system. Also there is a section in the help covering the same area:
There is an example Visual Basic project Supplied.
I hope this helps,
