After inserting the block, it is available as a special object in the Navigator. Therefore, editing is possible at any time. In the "Structure" tab, you can adjust the geometry parameters of the block as well as assign cross-sections and materials.
It is also possible to set the geometry parameters of the block to refer to any global parameter defined in the parameter list. To do this, use the Edit Formula function and assign a "global parameter." Thus, the geometry parameter changes automatically when the global parameter is changed.
You can also apply the optimization process to the block, as described in Chapter Optimization of Parameters.
