Teigha Civil’s 3D Feature Line Entity

AeccDbFeatureLine class

There are two ways of drawing feature lines: by 2D polyline (OdDbPolyline object) and by 3D polyline (OdDb3dPolyline object). The difference in elevation values affects all site feature edge points.

Using the OdPrcCreate Example

The main Teigha PRC example for “how to create” is the OdPrcCreate example located in the \Prc\Examples\OdPrcCreate folder. The release package includes a prebuilt OdPrcCreate.exe application in the “exe” folder. Also a project file is available in the release packages (for Microsoft® Windows®). So it is possible to start the prebuilt application or debug it using Microsoft Visual Studio.

Questions and Answers about PDF Export Settings and Plot Settings
