The Rebar Round Up tab allows you to define bar length and spacing detailing options. You can input length and spacing distance rounding for bar length round up, input bar spacing round down and stirrup spacing round down properties and input bar spacing limits (RC mode only). You can also define a bar length library that the program can use the bar lengths from, to standardize rebar lengths generated by the software, or import the library values from a TXT (text) file.
