Create Tangential Faces

Advanced Face Modeling Package

General

  • This feature is enabled if you have the Advanced Face Modeling Functions add-on option.
  • The face selected with the function is made a tangential face to the faces surrounding it.
  • If necessary, you can select one or more face edge lines to which tangentiality is added. This creates a sharp corner at the other edge lines.
    • If you do not select any face edge lines, the face will be tangential to all edge lines.
  • The higher the flattening, the lower the shape.
    • Zero represents kind of a default value.
    • The suitable value is determined experimentally and depends on the shape. For example, try values ​​between 0.1 and 2.

Create a Tangential Face

  1. Select the ribbon bar function Part | Faces | Create Tangential Faces or
    • Import | Faces | Create Tangential Faces.
  2. Click a face or faces.
  3. Select Confirm (Confirm = V key, middle mouse button or the context-sensitive function OK.)
    • The program opens the Create Tangential Face dialog box.
  4. Define the tangential face data in the dialog box.
    • Enter flattening.
      • Try the default value 0.
      • Change the factor moderately, if necessary.
    • Invert the face direction, if necessary
    • Adjust the maximum number of spans, if necessary.
    • Tangential geometry
      • Select the edge lines of the face where tangency takes place.
      • If you do not select edge lines, then tangency occurs at all edges.
    • If necessary, select the guide curve lines controlling the tangency
  5. Click Apply to see what kind of face the program creates with the values ​​you enter.
  6. If necessary, you can use the buttons to affect the faces to be replaced, the edges of the tangency face and the guide curves:
    • Add.
    • Change.
    • Delete.
  7. Select OK.

Editing the selected face into a tangential face

  1. Select one or more faces in a part model.
    • Hold down the Ctrl key if you select more than one face.
  2. Select the context-sensitive function Faces> Make Tangential.
    • The program opens the Create Tangential Face dialog box.
  3. Continue as above, steps 4...7.

Example 1

Comparison of the tangential face of a sharp-cornered part and a part with corners rounded.
  • The flattening is 0 (zero) in both.
  • The example shows that the function is applicable mainly only to faces with non-sharp corners.

Example 2

Comparison when tangential geometry is or is not selected
  • No tangential edge is selected in the upper image.
  • In the lower image, one line (yellow) is selected as the tangential edge line.
  • The flattening is 0 (zero) in both.

Example 3

  • In the image, different tangency factors have been used for the same cross section.
