8. DXF

DXF Import-Export

This duo of commands serves as a gate between LightWave and a professional CAD

programs. Imported geometry is now imported into there individual corresponding

layers transferred with the corresponding sketch color information. When exporting all geometry, the selected layer is exported and each sketch color is exported as a

different layer.

DXF Import

Supported Entities

• TABLES: Tables
• LAYERS: Layers
• BLOCKS: Blocks
• ENTITIES: Entities
• ARC: Circle arc.
• CIRCLE: Circle.
• ELLIPSE: Ellipse or elliptic arc.
• INSERT:
• LINE: Simple line.
• POLYLINE: Polyline or polyface mesh.
• SPLINE: Spline curve with maximal degree 6.

An imported DXF file can be blocks. Blocks will be replaced by geometry when they

are assembled. Every unsupported entity or parameter is ignored.

DXF Export

The DXF export will discard all layered information from LightWave on export. All

information will be placed into a single layer. This is a limitation of Lightwave.

Exported entities:

• NURB CURVES: Nurb Curves
• POLYGONS: Triangle or square (more than four point polygon are triangulated).

Indexation of complex meshes will be not preserved.
