Draw Lines with the End User

[colli123]

Hello Community!

I'm looking for possibility to draw lines by using the end-user.
In the end the programm should do the exact same thing as the sketchLine Button in Inventor.
One way would be, to simulate a mouse click on the sketchLine button:

oCommandMgr.ControlDefinitions.Item("SketchLineCmd")
oControlDef.Execute()

 But I'm looking for way to get the processes that the sketchLine button in Inventor performs into a code.
I assume that you have to guide the end-user and his inputs with events, but i don't now how.
I was looking for similiar examples in the API Help and in the internet, but i couldn't find any until now.
Does someone have an idea how to get that into code?

Best regards
