To define clusters for support

Specify collections of triangles for generating support structures on them

Clusters may be defined in two ways, adjusting the values in the cluster detection, or manually marking and unmarking triangles. The two methods cannot be combined.

Cluster detection was called Downskin Analysis in earlier versions of Netfabb.

Note: These steps assume you have loaded a part and launched the support module on it.

To define clusters for support through cluster detection

Tip: To learn about cluster detection, in particular to the meaning of critical and non-critical angles, refer to the Support Module Reference.

1. In the support module's context view, find the first tab, Analysis.
2. Adjust the sliders to meet your printing needs.

This updates the detected triangle groups instantly.

To define clusters for support through manual marking

1. From the menu, choose Cluster > Mark Cluster Manually.
2. Use the mouse to draw over the model and mark triangles. Marked triangles form clusters.
   Tip: To unmark triangles, hold the Ctrl key while drawing over triangles to be unmarked; and to change the size of the marking brush, choose the View tab from the context view and then adjust the value Mark cluster diameter.
