Viewing the Reference Vector Orientation for Characterised Surface Mesh Elements
Validate your model that contains characterised surface mesh elements, by viewing the
reference vector orientation.
On the 3D View
contextual tabs set, on the Mesh tab, in the
Rendering group, click the Orientation icon. From the drop-down list select the Characterised Surface icon.
Each face that has a characterised surface applied to, is listed on the
Characterised surface settings dialog.
For each face, you can select the Show U vector check
box to show the direction in the 3D view.
Click OK to close the dialog.
The start of the vector (the coordinate system origin) is indicated by a
yellow dot. The vector is displayed as a blue line to indicate that it is
aligned with the U reference direction.
