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. If all elevations are equal, the feature line will be drawn via an OdDbPolyline entity, else via OdDb3dPolyline.
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.
With the new release of Teigha 4.3.1, you can attach digital signatures to your .dwg files and validate a .dwg file’s digital signature. A digital signature indicates who the file came from and the file’s state when the digital signature was created, and validation confirms this information.
Similar to Teigha Drawings, Teigha BIM also has visual styles for rendering elements in a View. However, with Teigha Drawings visual styles are separate elements in the database, and with Teigha BIM visual styles are part of the View.

There is often a misunderstanding between general plot settings and specific settings for exporting drawings to .pdf files. This can lead to a misunderstanding of how to implement a feature for exporting a drawing, and we also receive suggestions to add functionality to the PDF export settings when that functionality already exists in the general plot settings.
This article shows how to launch the "multi-user editor."
Note: The xml schema (TD.txds) must be in the same folder as OdaMfcApp.exe.
BOM (Bill Of Materials) Manager is a service class that works with BOM tables, part references and BOM rows. All data held by BOM tables is stored in data containers that call data entries. There are three data entry types: DataEntry, DataEntryPart, and DataEntryBlock. DataEntryPart is connected with part references, and DataEntryBlock is connected with components.
Sometimes it is necessary to export a drawing to the PDF format as a grayscale or monochrome document. The usual way to do it is using plot styles: monochrome.ctb/stb and grayscale.ctb/stb.
