Performing a Cutout Analysis

You can check that a surface or a 3D curve can be cut out.

  1. From the Analysis & Preparation section of the action bar, click Cutout Analysis .
  2. Select an axis system (stamping direction).

    The Z-Axis represents the cutting tool axis.

  3. Select the surface or 3D curve to analyze with respect to an allowed cutout angle.

    Note: To change the selection, either exit Cutout Analysis and restart it with another input, or edit the mesh surface in the tree.

    1. If you have selected a 3D curve, select a surface.

      Cutout Analysis retrieves the normals of the 3D curve with respect to this surface.

  4. Select an analysis method.
    • Analyze Normals: Computes the angle between the normals (Of the surface, or of the curve with respect to its support surface) and the Z Axis of the stamping direction.
    • Analyze Shear Angle: Computes the shear angle (Angle between the tangents of the trim line and the tool direction).
    • Analyze 2D Angles
      • Projects the trim line on the plane normal to the stamping direction.
      • Then computes the angle between the tangents of the projected trim lines and the Z Axis of the stamping direction.
    • Analyze 3D Angles: Computes the trim angle (Angle between the normals of the trim line and the tool direction).
    • Analyze Insertion Depth: Checks that the travel of a cutting tool ensures a complete cut of the material. The cam direction can be optimized according to this analysis.
    • Pierce Analysis: Checks whether the input direction of the hole (painting, mounting or position hole) can be cut with the corresponding tolerances.

      For more information, see Analyzing Piercing of Holes.

  5. Optional: Except for Analyze Shear Angle, select a support surface (If you have selected a 3D curve).
  6. Activate more options:
    • Compute Areas
    • Fly Analysis
    • Reverse Normals
  7. Select a Color Mode
    • Detailed
    • Face/Edge
    • Smooth.
  8. Set the View Mode for the analysis.

    • Mesh
    • Vectors
    • Planes
    • Dots
    • Acute/Obtuse Dots

  9. Set the Mesh Behavior.
    1. Enter the Interval Step.
    2. Enter the Lay Down Tolerance.
    The Maximum Lay Down Deviation is displayed.
  10. Go to Extract Geometry to convert the results of the displayed analysis to dead geometry.
    • Extract Areas: Stores the results as dead geometries and 3D labels.
    • Extract Direction: Extracts the Z-Axis on each analyzed point.
    • Extract Geometries as Points.
    • Extract Values as Tags or Points.
    • Extract Points Number using Full, Minima and Maxima or User Selection.

A Set of Trim Line Checks is created. It contains Trim Line Check Set with a mesh of the analyzed element and the cutout analysis.
