[Solved] When Customizing Mech-Vision Output, Mech-Viz Cannot Read Pose and Won’t Start

[Mech-Mind-Barry]

Sorry for the inconvenience—here is the definitive fix.

Root cause
Mech-Viz only reads poses that are explicitly packaged inside the WorkObject data structure. If your custom output omits WorkObject, the pose is invisible to Mech-Viz and the project refuses to run.

Step-by-step solution (no code changes required)

1. In Mech-Vision, open the Output step.
   

   

2. Tick “Enable WorkObject data in output”.

3. Under “Labels to send out”, check the labels you actually need (usually “pose”, “id”, etc.).

4. Add the step “Generate Picking Strategy for Target Object”.
   • Inside this step, set “Select based on picking point”.
   

   

5. Draw a connection from the “Generate Picking Strategy” step to the “WorkObject_data” port of the Output step.

6. Save and redeploy.
   

   

Result
Mech-Viz now receives a properly formed WorkObject containing the pose and starts without errors.

That’s all—happy picking!
