Inconsistency in Shear Design Search vs Design Check (Change 101)

Unknown design searches would sometimes report sections as passing, but performing a full design on the section results in a failed design. This was because Sizer was assuming the same load combination would be critical for the design of all sections. However, sometimes the section size does influence the critical loading, such as the distance d for which one ignores the effect of loads in determining critical shear (O86 5.5.5.2), and the wood volume that is used to determine glulam shear resistance ( CSA O86 6.5.7.2.1). In rare cases they can cause the critical load combination to change from one section size to another, so that the program is designing for a non-critical combination. This has been corrected and the program determines the critical combination for each section considered.
