Creating Corners

You can create a corner between two curves or between a point and a curve.

This task shows you how to:

Before you begin: Create a 3D shape containing two curves or a point and a curve.

Create a Corner on a Support

You can create a rounded corner of specified radius between two elements on the defined support.

  1. From the Wireframe section of the action bar, click Corner .
  2. In the Corner Type list, select Corner On Support.
  3. In the Element 1 box, select a curve or a point as first reference element.
  4. In the Element 2 box, select a curve as second reference element.
    The corner will be created between these two references.
  5. In the Support box, select the surface.
    The support can be a surface or a plane.The resulting corner is a curve seen as an arc of circle lying on a support place or surface.

    Important:
    • The reference elements must lie on this support, as well as the center of the circle defining the corner. Moreover, the laid elements must be connected.
    • In a power copy or user feature context, it is advised to evaluate the Support box.
  6. In the Radius box, enter the value or use the arrows to change the value.

    Note: In the case of a curve as Element 1, all corners have the same radius, and closed wires can be selected.

  7. Click OK to create the corner.
    The corner (identified as Corner.xxx) is added to the tree.

Create a 3D Corner

You can create a 3D corner of specified radius between two elements.

  1. Click Corner .
  2. In the Corner Type list, select 3D Corner.
  3. In the Element 1 box, select a 3D curve or a point as first reference element.
  4. In the Element 2 box, select a 3D curve as second reference element.
    The corner will be created between these two references.
  5. Optional: In the Direction box, select a direction.
    • If you select a direction, the corner will be computed according to this direction. You can clear the selection by selecting Clear Selection from the context menu.
    • If you do not select a direction, the optimal direction is computed.

    • If no direction is specified or if you select a direction from the context menu (

      Edit Components, X, Y,or Z Axis), a red arrow is displayed in the 3D geometry representing the direction.

    The resulting corner is a 3D curve seen as an arc of circle along the input direction.



    Important: The input elements must not be collinear to the 3D Corner direction. Moreover, if the plane projection of an input element along the user input direction is singular or is self intersected, some corner solution might not be computed.
  6. In the Radius box, type the radius value or use the arrows to change the value.

    Note: In the case of a curve as Element 1, all corners have the same radius, and closed wires can be selected.

  7. Click OK to create the corner.
    The corner (identified as Corner.xxx) is added to the tree.
    Important: Several solutions may be possible, so click Next Solution to move to another corner solution, or directly select the corner you want in the geometry.

Create a Corner on a Vertex

You can create a rounded corner of specified radius on vertex.

Select the Corner On Vertex check box option to create a corner by selecting, as Element 1 (Element 2 is dimmed):
  • a point





  • a curve:





Important: You can select the Trim element check boxes if you want to trim and assemble the two reference elements to the corner.

The elements can be trimmed and assembled individually.
