Fail to create Analytical Panel in Robot by Dynamo

[Xiaofei_Ying]

I create a 2D surface in the XY plane. I try to export it to Robot, but failed

Error:
AnalyticalPanel.BySurface
Invalid project type. 3D project in the Robot Structural Analysis is required for proper Dynamo operation.

What type of project are u running?
structures

I always use ‘shell design’

could that be your problem?

Thank you for the tip.
I also realize the structure type is the culprit.
