Sometimes, some elements are in a concrete quality other than my request, or I need to pass from C25 to C30 to recover the column-beam junction safety. Is there a practical way to make all the elements C30 at once?
Hello. Activate the Structure tree view on the left, double-click the material you use in the Materials list. Enter properties and change Concrete characteristic compressive strength. You change the material properties of all elements using this material at once.
