How Number of Cuts (NCUTS) Work

The values assigned to parameter 4 are important in how they apply to the design. Any positive values of NCUTs from zero will be interpreted in the design as the number of cuts so if parameter 4 is set to 3 then the design component will have 3 cuts regardless of the setting in Model. Setting parameter 4 to 0 will mean that the bend is treated like a pulled bend and will not have any cuts available.

This means that the parameter4 setting will override any changes to the NCUTS attribute in Model and the user will not be able to modify it. This is necessary so that the type of bends to be used can be controlled via a specification and so that Isodraft can get the correct Symbol Key (SKEY) and number of cuts.

If the user wants to have fully variable cuts and freedom to re-specify NCUTS then setting parameter 4 to a negative number will result in an uncontrolled bend where the user must specify how many cuts to use. The maximum number of cuts per bend is 25.
