Build Polygonal Solids

On the Wireframe tab, in the From Strings group: Click Build Polygonal Solids to generate polygonal solids that are mapped to the sections in an input (String or Outline) file. An associated set of nominal section planes, with Away and Towards measurements defined for each section plane, must also be defined in a section control file.

Using the orientation of the nominal section plane, each polygon is projected onto the "Away" and "Towards" planes. The projections are then wireframed and closed to form a solid.

Polygonal solids can be used in a Grade Tonnage Report (the Wireframe tab, in the Report group) to create a result equivalent to a Polygonal Section Estimate Report.

String File

If String file is chosen as the input option for polygonal sections, double-click to select a String file as the clipping file. If required, define a filter to selectively control the records to be processed.

East and North and Z fields

Specify the names of the fields in which Easting, Northing, and Z coordinates are stored in the string file.

Join field

In forms that require polylines as an input, the values in this field define whether the data points in the input file should be joined by a line. If successive records have the same value in this field, a line will join the points. If two-factor topology is required, the values in a String field may also be used to segment the lines.

String field

In most forms, the String field is an optional generic attribute used to store a secondary input such as a code. Traditionally, this field has also been used with the Join field to define whether data points should be joined by a line, or strung, hence the name.

Outline File

If Outline file is chosen as the input option, click the More button to open the Outline Restrictions form.

Run

On the Wireframe Definition tab of the form, navigate to the section control file that will be used by the process, and set the attributes of the output wireframe. Finally, click Run to run the process.
