Offsetting 3D Elements Associatively

You can create an offset use-edge that will be associative to a 3D element (surface or edge).

Before you begin:
  • Open a 3D shape representation containing a layout.
  • Open the layout in the 2D window, alongside the 3D window.

Offsetting 2D Elements
  1. From the Sketch section of the action bar, click Offset 3D Elements .

    The Tools Palette appears.

  2. Select the 3D element you want to offset. This can be either a surface or an edge.
    The Tools Palette is updated.

    The followings options are proposed:

    • No Propagation : offsets only the element you select.

      For a 3D surface it has the same effect as Point Propagation, because the nearest boundary is offset.

    • Tangent Propagation : offsets the element you select as well as the elements tangent to it (closest edge of the face, and all tangent edges).
    • Point Propagation : duplicates the element you select as well as connex elements (closest edge of the face, and all continuous edges).
    • Both Side Offset : duplicates the element you select on both sides of this element. This option can be used while using any of the three options mentioned above.

    A preview of the elements to be created appears as you drag the cursor.

    • Offset: defines the offset value precisely.
    • Instance(s): defines the number of elements you want to obtain after the offset operation.

  3. In the Instances box of the Tools Palette, enter the number of offset instances you want to create.
  4. You can define the location of the offset use-edge using either the mouse or a specific value. Make either of the following operations:
    • Select a point or click where you want the new element to be located.
    • Define the location precisely by entering a value in the Offset box.
  5. Press Enter.
    A new offset 2D element of the same type as the original projected 3D element is created.
    Important:

    An Offset Geometry Set object is created in the tree.

    Double-click this object to open the Offset Definition dialog box and modify the offset specifications.

The offset use-edge is created. It is associative to its reference element. As an example, the offset use-edge below was created using No Propagation and Both Side Offset:
