# splitSurfaceByIsoparam

This option is useful when a surface needs to be split at a given isoparametric curve. This operation may be used to separate surfaces with extreme curvatures in different parts.

## Inline mode usage

splitSurfaceByIsoparam -h
Displays the help file that summarizes the parameters for this command.
splitSurfaceByIsoparam–s <surface> -p <parametric_value>
Splits a selected surface by an isoparametric line in the u-dimension
splitSurfaceByIsoparam–u –s <surface> -p <parametric_value>
Splits a selected surface by an isoparametric line in the u-dimension
splitSurfaceByIsoparam–v –s <surface> -p <parametric_value>
Splits a selected surface by an isoparametric line in the v-dimension

## Interactive mode usage
