TRUNCATE

Function:

Stops rounding remainders of dimensioning being added to the next dimension.

Description:

When dimensioned isometrics are plotted, all dimensions are rounded up or down to the nearest mm or 1/16 inch, depending on the current output units. By default, Isodraft carries over any remainder (positive or negative) from a rounded dimension and adds it to the adjacent dimension. This process minimizes cumulative errors over a number of consecutive dimensions, but it can result in identical fittings being shown with different lengths (usually differing by 1mm or 1/16 inch).

The user can specify that Isodraft is to truncate all dimensions. The remainders from rounding of the individual dimensions will then be discarded rather than added to the next dimension. Remember that this can result in a significant cumulative error over long pipelines with many individually dimensioned components.

Examples:

TRUNcate ON

TRUNcate OFF

TRUNcate DEFault

Truncates dimensions.

Does not truncate dimensions
