This <a href="/conv/exp_dwf.htm">exporter</a> outputs full 3D scenes to the <a href="http://www.autodesk.com/dwf">Autodesk DWF 3D file format</a>, including mesh, polyline and trimmed NURBS geometry, object/light/camera/material animation data, materials  with embedded texture maps, lights, cameras and a plethora of options to output highly  optimized files. The structure of the DWF file format is ideal for creating highly  compressed files for Internet download.

<p> Please also refer to the corresponding <a href="/conv/imp_dwf.htm">DWF-3D import converter</a>.

The <a href="/conv/exp_dxf.htm">DXF and DWG geometry export converter</a> writes out the scene database as either 3-point or 4-point polygons using the 3DFACE or PolyFace mesh entities. Polygons with 5 or more vertices, concave polygons, or polygons  with holes are automatically triangulated.

The Okino <a href="/conv/exp_dgn.htm">DGN export converter</a> module allows various types of 3D geometry, hierarchy and materials (assembly data) to be exported to native .dgn v8 disk based files which are usually associated with the Bentley MicroStation program.

<p>Please also refer to the corresponding <a href="/conv/imp_dgn.htm">DGN import converter</a> and its extensive explanations.

NOTES-START
This <a href="/conv/exp_iges.htm">IGES export converter</a> allows trimmed NURBS and polygonal data to be exported in various flavors of the IGES file format. This export converter is useful for transferring data to various brands of CAD/CAM software, many of which will be able to read the IGES data exported from this converter.

<p> In general most CAD programs which accept IGES files require that the geometry data be "trimmed NURBS" or "BREP solids". This IGES exporter  will only output "trimmed NURBS" (in IGES entities 144/142/128) when the source data is also "trimmed NURBS", such as from Softimage-3D or Maya (and only when the geometry data was modeled as NURBS and not polygons).

<p>This IGES exporter can also output all 3D geometry items as pure polygons meshes, as IGES entity # 106 (copious data). However, as outlined in the  next paragraph, this option tends to confuse users of this IGES exporter since they expect such #106 data to be read into all CAD modelers. In general there are very few CAD programs which will import and accept #106 copious data polygon meshes because they only accept NURBS and not meshes. This option to output #106 copious data was added for one customer who wanted to output a text font outline to Pro/Engineer, after which the data was imported as a 2D drafting outline, traced, and turned into a 3D model using interactive Pro/E drawing tools.

<p>¥ Important Notice ¥ This export converter CANNOT convert polygon mesh data to an IGES file as NURBS or solids. It is a very common request that Okino customers will want to take polygon mesh data from programs such as SketchUp, 3ds Max, Maya, CINEMA-4D, etc. into solids modeling programs such as ProE/Creo, SolidWorks, Solid Edge, Autodesk Inventor, etc. This is just not possible, even if you don't believe it. Solids modelers require that the IGES file only contains trimmed NURBS data, usually with additional BREP stitching data to make the trimmed NURBS into "solids". Polygon mesh data cannot be converted back to trimmed NURBS or solids simply by exporting to IGES; to do that you will need to purchase a "surface reconstruction" program which allows you to interactively reconstruct a NURBS model out of a mesh model, and only then will you be able to export a newly reconstructed NURBS surface to an IGES file.
