Creating Bumped Elements

You can create bumped elements by deformation of an initial element.

Before you begin:
  • You must have access to the Generative Shape Morphing app.
  • Create a 3D shape containing a surface and a point.
  1. From the Morphing section of the action bar, click Bump .
  2. In the Element to deform box, select the curve or the surface to be deformed.


  3. In the Limit curve box, select the limiting curve to delimit the deformation area.
    The limit curve must lie on the element to be deformed.
    Tip: If not, use the Create Projection context menu on the Limit curve box to project the limit curve on the element.


  4. In the Deformation center box, select the point representing the center of the deformation.
    The deviation will be maximum at this point, and evolve towards the limit curve, where it should reach 0.

  5. In the Deformation direction box, select the curve indicating the deformation direction.
    The deformation is propagated along this direction. By default, the deformation direction is normal to the deformed element.

  6. In the Deformation distance box, set the maximum distance, along the deformation direction, from the deformed surface towards the deformation center.

    • Continuity: Defines the continuity to be kept between the deformed area and the surface outside the deformation area (point, tangent, or curvature continuity).
    • Projection direction: Specify a projection direction if the deformation center does not lie within the selected element to be deformed.
    • Center Curvature: Define a center curvature value to control the shape of the bump deformation. If the value is:
      • Equal to 1 (case A), the shape is the default one (as if no value was defined)
      • Smaller than 1 (case B), the shape is flatter
      • Bigger than 1 (case C), the shape is steeper.
      Note: All values are allowed (positive, null, and negative values), however it is advised to define a value comprised between -1 and 5.


      Important: In case of curvature continuity, the original continuity between the deformed area and the surface outside the deformation area will be at best kept but may be approximate in certain cases.
