Add Precamber
If this is checked, SpanMan will automatically add precamber to members longer than 6000 mm
if it will result in a smaller size.
If precamber is added it is visible in the SECTIONS list next to the section's name when you press Design and in the title of the CERTIFICATE and CALCULATIONS.
The minimum precamber SpanMan uses is 20 mm. Beams with less precamber than 20 mm are difficult to fabricate.
