Extend Planar & Cones : Options and Results

Access: Open this function from one of the following locations:

Extend stitched adjacent simple faces to reach a reference geometry (closed sketch, closed 2D composite or planar face).

This function enables you to extend adjacent planar, cylindrical or conic faces (belonging to the same object) or NURBs that can be simplified to these types) for creating Binder Faces.

Required Step 1

Pick adjacent planar, cone or cylindrical faces.

Note: The selected faces MUST be adjacent and belong to the same object (meaning, you cannot select faces from different objects).

Original faces:

Faces selected:

Required Step 2

Pick a reference entity to which the selected faces will be extended and set the parameters. This reference entity can be a reference closed sketch, closed 2D composite or planar face. In the example below, a closed sketch is selected.

The following parameters/options are displayed:

New Face

This is a toggle option: New Face / Same Face.

New Face

Extend the selected faces to the reference entity. The extension is regarded as a collection of new faces. See the examples below.

Same Face

Extend the selected faces to the reference entity. The extension is regarded as the same faces as the originally selected face. In this case the extension has the same color as the original faces. See the examples below.

Examples:Examples:

Original faces:

Faces extended to sketch:
New Face option:

Faces extended to sketch:
Same Face option:

Note: When creating parting surfaces in the Assembly environment, if the faces selected in step 1 belong to an external (non-active part), the following occurs when switching to step 2:

  1. The body (owner of the selected faces) becomes transparent, to improve clarity.

  2. The New Face option is displayed grayed out (the Same Face option is not available).

  3. The new faces are created in the active part.

Examples:Examples:

The selected faces belong to a non-active part, the New Face option is displayed grayed out:

The new faces are created in the active part:

 

Upper/Lower Delta

This parameter controls the extension value of faces that are vertical (or almost vertical) to the picked wire/sketch plane. It controls the cupping plane/face of the upper and lower bounding box of the selected faces. When the result is created, the faces will be extended towards an imaginary sweep face created by this sketch. It is created, as follows:

    • The system creates (internally) a bounding box of the part using the UCS defined by the sketcher plane.

    • The system then creates an imaginary sweep face that runs from the lower plane (parallel to the lower box boundary with the defined delta) to the upper plane (parallel to the upper box boundary with the defined delta).

    • The extension will end based on this imaginary sweep face.

Note: This parameter is mainly used to control the extension value of faces that are vertical (or almost vertical) to the picked wire/sketch plane.

Optional Step 1

Unselect the required closed edges that you do not want to include in the extend operation. For example:

Pick the required edge(s).

If required, select Reset Selection to clear the selection. This option is grayed out until the first edge is picked.
