RR 22.02.00-2.6 Physical Modeler Edit Surface Mode
STAAD.Pro物理モデラー has a new tool which allows you to edit surfaces (such as materials, thickness, openings, etc.) in an isolated, elevation view. You can then merge the surface edits back to your main model.
Refer to the STAAD.Pro物理モデラー help for additional details on adding polygonal openings and adding circular openings to surfaces using this feature.
