    The Part Section.svg Part Section command creates wire geometry at the intersections of two objects. The result is fully parametric.

    • An intersection of two solids/faces results in one or more section lines.
    • An intersection of two lines, or a line and a solid/face, results in one or more points.

    1. Select two objects.
    2. The first object will be the DataBase of the Section, but the selection order has no impact on the result.
    3. There are several ways to invoke the command:
      • Press the Part Section.svg Section button.
      • Select the Part → Part Section.svg Section option from the menu.

    A PartDesign Section object is derived from a Part Feature object and inherits all its properties. It also has the following additional properties:



    • DataBase (Link): Link to the first object.
    • DataTool (Link): Link to the second object.


    • Data (hidden)History (ShapeHistory): "Shape history".
    • DataRefine (Bool): "Refine shape (clean up redundant edges) after this boolean operation". The default value is determined by the Automatically refine model after sketch-based operation preference. See PartDesign Preferences.


    • DataApproximation (Bool): Approximate the output edges.
