Intersecting 3D Elements with the Sketch Plane

You can create an intersection between a face and a sketch plane.

This task shows you how to:

Before you begin: Create a simple 3D shape similar to the one below.

Intersect 3D Elements

  1. From the Sketch section of the action bar, click Intersect 3D Elements .
    The Intersection Definition dialog box appears.
  2. In the Element(s) to intersect box, select the face of interest.


  3. Optional: In the Near element box, select the element of interest.
    The minimal distance is computed between each domain and the near element to keep the nearest solution.
  4. Optional: Select the No Canonical Curve check box to create a complex curve instead of canonical curve.

    Notes:
    • The No Canonical Curve check box is cleared by default. In this case, a canonicity detection is performed on intersected curves according to the app tolerance, in other words the app tries to recognize sketcher elements like line or conic curves.
    • The No Canonical Curve check box is not taken into account if you activate Create Datum mode in App Options panel.

  5. Click OK.
    The app computes and displays the intersection between the face and the sketch plane. The intersection is yellow meaning that you cannot move it.

    The node (identified as Intersection.x) is added to the tree.

    Note: If you select the curved surface of a cylindrical face, you can select one of the following elements:
    • Circular edge: This is the default selection.
    • Axis: Right-click the selected surface and select Select Axis.

Intersect using Select Boundary Edges

  1. From the Sketch section of the action bar, click Intersect 3D Elements .
    The Intersection Definition dialog box appears.
  2. In the Element(s) to intersect box, select the faces of interest.
  3. Right-click on the selected face(s) and select Select Boundary Edges from the contextual menu.
    Every element of the selected faces is now pointed as a Reference Element.
    Note: You can also select Select Boundary Edges for the selected face(s) first and then select the command Intersect 3D Elements .
  4. Click Ok.
    The app computes and displays the intersection of the selected boundary edges of the faces and the sketch plane. An Intersection.x node is created in the tree under which Mark.x node is created for each intersected element.
