Surface Menu
The Surface Menu allows one to find information and set parameters for surfaces viewed in Workbench.

- Information... will open a popup that shows geometric information on the surface being viewed in the current Active Tab. If the active tab does not contain a surface, this option is inactive.

- Surface Properties sets display options for all surfaces across a Workbench session.

> - Display Normal Vectors sets whether vectors at 90 degrees to the surface will be shown for each vertex.

> - Drawing Type sets how the surface mesh is drawn in wb_view.
> - Hide hides the surface and all layers drawn on it.
> - Links (Edges) shows the links between surface vertices giving a mesh appearance.
> - Vertices shows only the vertex points across the surface.
> - Triangles shows the full surface (mesh filled in with interpolated information between the vertices).

> - Link Diameter sets the diameter of the links when in Links (Edges) drawing mode.

> - Vertex diameter sets the diameter of vertices when in Vertices drawing mode.
> - Opacity sets the opacity of the surface when in Triangles drawing mode. Opacity in the Overlay Toolbox sets layer opacity.
> - Volume interaction sets the surface used for mapping to volume voxels. This is used in the Volume/Surface Outline feature and for volume to vertex identification.
