Manually specify clusters for support actions to generate structures on
Areas of contiguous triangles that are relevant for support generation are called clusters. During manual work, they are defined in one of two ways:
- Let Netfabb analyze the mesh and mark areas of triangles based on their angle and surrounding, qualifying triangles
- Use a brush tool to manually mark and unmark areas of triangles
The two methods cannot be combined.
To define clusters for support through cluster detection
Tip: To learn more about cluster detection, in particular to the meaning of critical and non-critical angles, refer to the
Support Editor Reference.
- In the support editor's context view, select the first tab, Analysis.
- Adjust the Cluster detection sliders to meet your printing needs.
This updates the detected triangle groups instantly.
To define clusters for support through manual marking
- From the menu, choose
Cluster >
Mark cluster manually.
- Use the mouse to draw over the model and mark triangles. Marked triangles form clusters.
- To unmark triangles, hold the Ctrl key while drawing over triangles to be unmarked
- To change the size of the marking brush, change View tab from the context view and then adjust the value Brush size on the Analysis tab, or use Ctrl+Scrollwheel.
-
To avoid the brush fill bleeding into perforations or around sharp edges, use the
Edge threshold control.
