The 2021.d version includes the new tool "Lock/Unlock perimeter" in the "Punching shear" option ("Results" tab > "Slabs/Waffle slabs" menu > "Punching shear" option). Using this tool, users can lock as many perimeters of the supports as they wish. This way, each time the project is analysed or when punching shear perimeters are regenerated, only those that have not been locked will be generated.
