Description
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.
Usage
- 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 VueDisplay 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 VueShape Color of the mesh object should not be red.
- The VueDisplay Mode of the mesh object ideally should be
- Select a single mesh object.
- Select the Meshes → Create mesh segments from best-fit surfaces... option from the menu.
- The Mesh segmentation task panel opens.
- 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.
- Select the surface type(s) you wish to create mesh segments for:
- Plane
- Cylinder
- Sphere
- Specify the Tolerance values.
- Specify the Minimum number of faces values.
- Press the OK button.
- The command will create a group containing separate mesh objects, each a segment of the original mesh object.
- If the created group is empty try using the command again with modified settings.
