    Option Description
    1. Select lines.
    2. In the microdialog, select a projection method.

      Along vector allows you to define a direction using the Vector tool.

    3. Choose between trimming the entire surface or trimming only a user-specified distance. If you choose to use a specific distance, define a value.
    4. Click Split on the guide bar.
    Note: This option is only available when solids or surfaces are the target. To split a line, you must select the target and cut line, then click Split. Multiple target lines can be defined; however, only one single cut line can be defined.
    Bounding Lines Select bounding lines.
    Note: This option is only available when solids are the target.
    Offset Lines
    1. Select lines.
    2. Enter an offset distance in the microdialog.
    • This option is only available when surfaces are the target.
    • A Washer split anchor is added for quick execution of the split. You can select a line, usually a free edge with a cutout to create the split. This is useful when creating a washer split around a hole. A specific distance can be entered into the microdialog.
