7.1.4. DWG and DXF Files

JetStream Roamer's .dwg and .dxf file reader uses Autodesk's ObjectDBX™ technology and so is

guaranteed to read all object geometry and information for those third party applications that utilize the

ObjectDBX Framework.

The reader currently supports all surface (shaded) entities (3D faces, rectangular meshes, polyface

meshes, circles, extruded lines and so on), including Proxy Graphics and custom objects such as ACIS

based entities (3D Solid, Region), lines, points and snap points. Complex entities (shapes, dimensions,

text) are not supported. The structure of the drawing is preserved including xrefs, blocks, inserts,

AutoCAD color index, layers, views and active viewpoint. Entities are colored using the AutoCAD Color

Index (ACI), so will match those in an AutoCAD "shaded" view.

There is also an .nwc file exporter for AutoCAD - see Section 7.2.1, “ AutoCAD .nwc Exporter ” for more

details.

Note

The reader supports files from all products based on AutoCAD 2007 and earlier.

Supported Entities

• All 2D and 3D geometry, including arcs, lines, polylines with non-zero thickness, ACIS objects (regions

and solids), polygon and polyface meshes, 3D faces and surfaces.

• Points and snap points

• Lines, polylines, circles, arcs with zero thickness.

• Named views.

• Layers.

• Colors.

• Blocks, inserts and multiple inserts.

• Groups.

• External references (xrefs).
