With Teigha you can create ACIS nurbs surfaces using a B-Rep Builder interface. Currently Teigha has two B-Rep Builder implementations: one in Teigha Kernel named AcisBrepBuilder and the other in Teigha BIM named BmBrepBuilder.
Creating Table Elements in .dgn Files
Table elements for .dgn files are supported by Bentley® MicroStation V8i Connect Edition and later. The structure and purpose of .dgn table elements are similar to .dwg table elements. A table is a set of cells arranged in rows and columns. The cells in a table are separated by gridlines, and .dgn table element cells can contain only text data.
To create a .dgn table element:
Introduction to Bill of Materials in Teigha Mechanical
Teigha Mechanical has a service (service class) named BOM Manager that provides an interface for Bill of Materials tables, parts, and components in a drawing. BOM Manager also provides an interface for BOM rows and their data.
Attaching windows to walls
In Teigha Architecture, objects can be attached to other objects. Such connections are handled by special anchor objects which are stored in a .dwg file just like any other object. An anchor is represented by the base class AECDbAnchor. The meaning of the connection between objects can be different: for example, windows are inserted in a wall, or a schedule table is attached to an object.
Raster Reference Element Feature in .dgn Files
A raster reference element (OdDgReferenceAttachmentHeader) is actually a non-graphical element that has no graphical element properties as level properties, etc. It can’t be selected like other elements. In fact there is a display and selection problem with it.
Part References Overview
Part references are used to pick any geometry and mark it as a part. The referenced part will have a special behavior that allows it to interact with Bill Of Materials and allows it to be included in other drawings or assemblies through xreferences.
