Hey together,
I’m a new RS-User. In one of my first projects I have a wobj which is once moved from an external axis. On the Robot I realised this movement with: “wobj.oframe.trans.x:=x”
Now I would like to visualize this movement during the simulation. How can I connect a geometry (it’s from a CAD-File) with the wobj? I tried it with Smart objects, but the attach-function does not show me the “T\_ROB1/wobj”.
What’s the easiest eway to realise this connection?
Best,
Johannes

Normally you link a wobj to a geometry.
First you create a mechanism, which has a baseframe. Then you connect that device to your external axis, and create a wobj that is connected to the mechanism.
You now have a wobj that will follow the external axis.
