Question:
I have selected all members available for design in RF‑/TIMBER Pro. Why are the tapered members not designed?
Answer:
Presumably, the "Stress point design also for rectangular and circular cross-sections" option in Details is activated.
Since the stress point design is not allowed for tapered members, this function must be deactivated, see the image.
If this option is to be considered despite the existing tapered cross-sections, the tapered members have to be designed in a separate design case.
