Smoothing The Surface

You can improve the smoothing of a surface onto a cloud of points after having completed a distance analysis and a reflect line analysis.

Before you begin:
  • Open a 3D shape containing windshields, for example, with style curves limiting these (windshield boundaries) style curves, onto which the roof should be mapped.
  • Make sure that the distance analysis is visible.

Using Control Points
  1. In Me > Preferences, set the attenuation factor to 0.01 (see Setting the Handles Attenuation Factor) and click OK.
  2. Select the roof surface and click Control Points .
    The Control Points dialog box appears.
  3. Click Local Normals .
  4. Click Constant Law .
  5. Right-click the Symmetry selection box and select Insert Wireframe > ZX Plane
  6. Double-click Symmetry to lock the functionality.
  7. Select U, V Orders , in the Tools Dashboard
  8. Set the order numbers to Nu=5 and Nv=7 using the context menu, to increase the number of mesh lines in U and V respectively.
    This brings more flexibility in terms of modifications.

  9. Decrease the deformation step to 0.75mm in the Tools Dashboard
  10. To avoid selecting points from the cloud, right-click the mesh and select Freeze.
  11. Select the central U mesh line and move it until you display green points instead of red points.
    You may also need to decrease the step and attenuation values and the number in U and V to reach a smoothed surface (a smoothed face is one displaying mostly green points, that is lying between -0.15mm and 0.15 mm from the cloud of points).
