Occasionally you may want to change the length of normals (lines indicating the normal direction of a face or vertex) to make them more visible or less distracting. You can change the scale of normals on a per-object basis.
Change the size of normals on polygonal surfaces (Method 1)
- Select the shape node Attribute Editor.
- Under the Mesh Component Display section, enable Display Normal and set the Normal Size.
Change the size of normals on polygonal surfaces (Method 2)
- Select the shape node Attribute Editor.
- Under the Mesh Component Display section, enable Display Normal.
- Select Display > Polygons > Normal Size to open the Normals Size editor. The editor reflects the current size of your normals. Enter a value or use the slider to adjust the normal size.
The range of the slider in the Normals Size editor is expandable and you can set normal sizes from a range of 0.02 to 10000.
The normal size is relative to the size of your object. For example, a small sphere with a normal size set to 10 has smaller normals than a larger sphere with a normal size set to 10.
If you have more than one object selected, and you select Display > Polygons > Normal Size, the normal size reflected in the Normal Size editor is that of the last selected object.
