DXF / DWG - DATA EXCHANGE FORMAT TO/FROM OTHER CAD SYSTEMS

The DXF format (drawing interchange file format) is a specific data exchange format acting between the most varied CAD systems worldwide. It is described as an industry standard as it is mainly deployed in this area.

DXF/DWG data exchange is used in construction to exchange graphical, non-object-oriented data.

Using the DXF format, geometries such as points, lines, surfaces and texts can be exchanged. Object information for civil engineering, such as alignments with their corresponding alignment information, are exchanged in simplified form. For example, alignments, including arcs and clothoids, are broken down into polygonal chains. For graphical representation, very useful; for technical use limited.

Geometries / information that can be exchanged with iTWO civil:

• Points, lines, surfaces, texts incl. representation information (color, layer assignation, dashing)
• Digital site models as 3DFACE or MESH
• Layer + name
• Point symbols
• Point information (e.g. name, specification) as text
