Beschreibung

The Mesh SegmentationBestFit command creates separate mesh segments for specified surface types of a mesh object. The command can also identify their parameters which can be useful when re-engineering a mesh object.

Anwendung

1. If you plan to identify the parameters of a surface type, note that the command uses the color red to mark the faces selected for this option. To see them properly:
   • The AnsichtDisplay Mode of the mesh object ideally should be Flat lines, but should at least show faces. If necessary use the Std DrawStyle command to override this property.
   • The AnsichtShape Color of the mesh object should not be red.
2. Select a single mesh object.
3. There are several ways to invoke the command:
   • Press the Create mesh segments from best-fit surfaces... button.
   • Select the Meshes → Create mesh segments from best-fit surfaces... option from the menu.
4. The Mesh segmentation task panel opens.
5. Optionally press one of the Parameters... buttons to identify the parameters of a surface:
   • The Surface fit dialog box opens.
   • Select one or more faces belonging to the surface:
     • Press the Region button and while holding down the left mouse button draw a region, a closed spline, in the 3D view. Faces that (partially) fall inside the region will be selected.
     • Press the Triangle button to select individual faces.
     • Optionally press the Clear button to clear the selection.
   • Press the Compute button to calculate the parameters.
   • Press the OK or Cancel button to close the dialog box.
6. Select the surface type(s) you wish to create mesh segments for:
   • Plane
   • Cylinder
   • Sphere
7. Specify the Tolerance values.
8. Specify the Minimum number of faces values.
9. Press the OK button.
10. The command will create a group containing separate mesh objects, each a segment of the original mesh object.
11. If the created group is empty try using the command again with modified settings.
