How can I calculate the bar length in Advance Concrete?

Bar length calculation is chosen from the "Preferences" button in the "Advance Project Preferences" toolbar.
There are the 4 following options to calculate the bar length:

1. Option "Exact"

This option calculates the length in the bar axis without considering the bar diameter. Take for example a rectangular bar.

The exact length of a rectangular bar with diameter ø10 is:

L = 4.15 m calculated as follows:
L = 4x0.960 + 3x0.024 + 2x0.035 + 2x0.084 = 4.150m

2. Option "Leg Sum"

This option calculates the length at the bar outward counting the diameter.

The length of a rectangular bar with diameter ø10 is calculated by summarizing the legs.
L = 4.21 m calculated as follows:
L = 4x1.000 + 2x0.105 = 4.210m

3. Option "Shape Based"

This option calculates the length in the bar axis using the formula from the shape catalog:

This option is available only for bars that have a shape code registered in the shape catalog together with a calculation formula.

L = 1.540m
L = 1.000 + 0.500 + 2*0.040 = 1.540m

If the bar does not have a shape code, the length is calculated with the first option "exact" (see 1^st point).

4. Option "Lengths between axes"

This option calculates the length in the bar axis.

The length of a rectangular bar with diameter ø10 is:
L= 4.160 m calculated as follows:
L = 4x0.990 + 2x0.100 = 4.160m

Note: The length of the bar, calculated in the 4 ways, will be consider in the bar list.
