Creating Points

Creating a Point on a Curve

Point lets you create a point on a curve at a distance from a reference point.

  1. Click Create new in the Choose a 3DShape dialog box.

    The New Content tab appears.
  2. Click 3D Shape under Physical Product Structure node in the New Content tab.
  3. Click OK in the 3D Shape dialog box.
    The new 3D Shape is created under the active product.
  4. Click OK in the 3D Shape dialog box.
    • The new 3D Shape is created under the active product.
    • The Axis System Definition dialog box appears. The axis system's parameters Origin, X axis, Y axis, and Z axis are automatically computed, and Default (Computed) appears in the boxes.
  • Important: You switch from Assembly Design app to the last representation app you used.
    1. Select On curve.
      Important:

      Repeat object after OK option has no effect in Assembly Design context.

    2. In the Point box, select a reference point.


      If this point is not on the curve, the minimum distance between the point and the curve is computed. If no point is selected, the curve's extremity is used as reference.
    3. Select one of the following options in the Distance to reference area to determine where the new point is to be created:
    4. Select how the distance is to be measured:
    5. Click Reverse Direction to display either the point on the other side of the reference point (if a point was selected originally) or the point from the other extremity (if no point was selected originally).
    6. Click OK to create the point.
      Important:
      • If the curve is infinite and no reference point is explicitly given, by default, the reference point is the projection of the model's origin.
      • If the curve is a closed curve, either the system detects a vertex on the curve that can be used as a reference point, or it creates an extremum point, and highlights it (you can then select another one if you want) or the system prompts you to manually select a reference point. Extremum points created on a closed curve are aggregated under their parent command and put in no show in the tree.

      • If the input point is selected automatically and you change the type, it is not retained to the new type. For instance, an extremum feature would not be retained if you change its type from On curve to Coordinates.
      • If the input for the curve is a feature, and an extremum point exits on this curve, the point is used as reference point. If the input for the curve is a part of a geometric feature (here an edge), and even though an extremum point already exists on this geometric feature, a new extremum is created.
      • If you change the type of an explicit point lying on the curve to On curve and select the curve on which the point lies, the point's original position on the curve is retained for a few seconds.
      Important: You come back in the Assembly Design app.
