RulerOp

Visualization and measurement capabilities are applied to a surface.

Inputs

The Input Surface is evaluated for visual inspection.

Parameters

The Ortho Grid draws three orthogonal planes perpendicular to the X, Y, Z world planes. These are either the three planes Behind Object or the three planes in front of it.

The Cross Grid draws cross sections of the input, also perpendicular to the world planes. The ortho and cross grids use the same grid spacing.

The Base controls the dynamic grid spacing. The default 'base 10' spacing specifies decimal grid steps. The spacing will exponentially adjust as the view point is adjusted. The intent is that the grid is neither too dense to read nor too sparse to judge.

A non-zero Excess will expand the bounding box used for the ortho grid.

Brush

Clicking the left mouse button on a surface will select a location on that surface. The middle mouse button can select a second location. Pressing the left or middle mouse button off the surface will deselect that location.

The coordinates of the two locations, if selected, will be written to an overlay near the top of edge the viewer pane. If both locations are selected, the delta and distance between the points are also written to the overlay.
