The grid ruler functions are available on the 3D Work Space menu:

3D Work Space ribbon containing UI controls

The drop down menu contains the following functions:

Creates a general Grid Ruler along the default axis. If no active work surface is set, the default axis is the X axis. The Grid Ruler can be placed on a different coordinate axis by pressing the down arrow and selecting the axis before placement.

When an active work surface is defined:

  • Only the relevant axes are available. For example, if the work surface lies in the X-plane, only the Y and Z axes are relevant.

  • The position of the Grid Ruler will snap to the work surface plane.

  • The label and tick orientation will be aligned with the work surface plane.

  • When moved in a graphical operation, the Grid Ruler is restricted to the active work surface plane and can only shift in the direction perpendicular to the ruler line.

Creates a ruler on the Z=0 plane when a work surface is defined. If no work surface is set, it operates the same as the Grid Ruler function.

Creates a ruler on the Y=0 plane when a work surface is defined. If no work surface is set, it operates the same as the Grid Ruler function.

Creates both a baseline and a centerline ruler when an active work surface is defined. If no work surface is set, it operates the same as the Grid Ruler function.

Inclined work surface

If the work surface is inclined (not aligned with an axis-parallel plane), the system automatically determines the closest axis-parallel plane and creates the Grid Ruler relative to it. This applies to:

  • Axis selection: If the inclined work surface is nearly aligned with the X-plane, Grid Rulers can be created along the Y and Z-axes. The same logic applies for surfaces that are almost aligned with the Y or Z-plane.

  • Tick orientation: The tick marks are aligned with the closest X, Y, or Z-plane.
