Analyzing the Pulling Direction

You can analyze a pulling direction and related draft angles, to make sure the part can be unmolded and to choose the best pulling direction. The analysis identifies zones on the analyzed surfaces where the deviation from the pulling direction at any point corresponds to specified values (draft angle ranges). These zones are displayed in the color specified for each value.

Defining the Projected Area as a Formula
  1. From the Analysis & Preparation section of the action bar, click Pulling Direction Analysis and select a set of surfaces to analyze.
    Element is updated accordingly.
    Notes:
    • For better performances, the projected area is computed only if the corresponding check box is selected.
      Note: Be careful to find and select the correct pulling direction before starting the computation. Too long a computation time indicates that the direction is not correct.
    • The projected area is computed for each given pulling direction. Its value is displayed in the current unit, but is not editable. It is not impacted by the draft angles.
  2. Define the Pulling Direction.
    • Select a line to take its orientation as the pulling direction.
    • Or select a plane to take its normal as the pulling direction.
    • Or right-click the Robot and select the required menu item.
  3. Click to avoid selecting another pulling direction by mistake.
  4. Under More >>, select and edit required draft angle ranges.
    1. Key in the value of each range, or use the arrows to modify it.
    2. Double-click a color to change it in the color editor.
  5. Click Reverse to visualize the zones to unmold in the opposite direction.
  6. Click Fly Analysis to display on the fly the normal to the face and the angle value between the pulling direction and the normal.


  7. Select the Smooth color check box to create a color gradation on the analyzed elements, thus providing more precise angle values.

    Gradations are created between each angle value. It is not a global gradation between -90 and 90 degrees.
