Sizer did not allow you to override the post and timber grade values in Table 5.3.1 D with the beam and stringer values in Table 5.3.1 C, as the note 2 in table 5.3.1D allows, based on the posts having been graded to beam and stringer rules. A setting has been added to the Design Settings allowing this. It defaults to unchecked, and is saved to both the project file and the ini file as default for new files.
