Answer:
You have probably carried out the design in RF‑/TIMBER Pro according to DIN 1052:2008 and used a cut-to-grain angle of less than 3° (see Image 01). According to Section 10.4.1 (1) of DIN 1052, such a cut-to-grain angle should not be considered. If you switch the design to the current DIN EN 1995 (see Image 02), the design will also be carried out for an angle of less than 3°.
Furthermore, the module allows you to analyze transversal tension stress in the apex, and so on, according to Section 6.4.3 ff. of the Eurocode. This procedure is explained in detail in this webinar.
