6.5. Building surface

To set the export options, click on the arrow on the right side of the Create surface for current structure button and select the Set surface creation parameters.... A dialog box, shown in Fig. 6.8, will be displayed.

• The smoothness of the surface is defined by the Smoothing pass count parameter. At zero value of the parameter form of a surface as close as possible to the structure. With an increase in the value the surface roughness disappear.
• The maximum number of polygons is defined by the Max triangles count parameter. Increase in the number of polygons increases the accuracy of the construction of the surface. If the specified number of polygons is redundant or not sufficient for the construction of the surface, the Viewer will use the value from the acceptable range that is closest to a given by user.
• The thickness of the shell is defined by the Shell thickness(mm) parameter. If the value is greater than zero shell has an inner and an outer surface. The both surfaces will be exported to file.
• To create the surface only for the largest structure, check the Remove secondary surfaces box.
• If the Use current clipping box is checked, then the surface is built only for that part of the structure, which is inside the cube. If the Clipping box tool is not active, this parameter is not used.

To apply the settings, click OK. To cancel the settings, click Cancel.
