3D Geometry Tab (Site Properties Dialog Box)

Use this tab to define how alignments and parcel geometry should be displayed when viewed in 3D.

Note:

These settings apply only to geometry. The display properties are defined by the style that the objects reference.

3D Geometry

Site Display Mode

Specifies how a site’s elevation is displayed in 3D:

  • Use Elevation: Displays the site geometry at the actual elevation to which it was drawn.
  • Flatten To Elevation: Displays the geometry flattened or projected to the elevation value specified by the Site Elevation property.
Site Elevation

Specifies the elevation used to flatten the geometry; enabled when the Site Display Mode property is set to Flatten To Elevation. All site geometry will be displayed at the specified elevation, regardless of the existing physical elevation of the geometry. The object elevations are not physically changed; they are only displayed at a single elevation.

Curve Tesselation: Mid-ordinate Distance

Specifies the mid-ordinate distance for the 3D polylines, which is used to tessellate the feature line and lot line arcs from which the polyline is being created.

Construction Geometry

Specifies the layers that construction geometry uses for 3D display.

When you create parcels or alignments, there may be solved and unsolved portions of the feature. The unsolved portion includes any unconnected elements of a feature.

For example, if you use the tan-tan method and create a number of lines, the whole feature is solved and the display characteristics are controlled by the parcel style. If you create some connected lines and then add a line that is not connected, the result is a piece of ‘construction’ geometry.

Construction Line Layer

Specifies the layer for line construction geometry. Click to open the Layer Selection dialog box where you can select a layer.

Construction Arc Layer

Specifies the layer for arc construction geometry. Click to open the Layer Selection dialog box where you can select a layer.

Construction Spiral Layer

Specifies the layer for spiral construction geometry. Not used.
