To perform the concrete design successfully, all parameters of the concrete objects must have been defined. This has been done for the surfaces, but not yet for the members and punching nodes. It is therefore required to exclude those objects from the design provisionally. Select the Objects to Design table for this purpose.
Clear the check boxes of the Members and Nodes with Punching object types (1) so that only the surfaces are designed. Then click the
button on the table toolbar to start the design (2).
