VSP3D Exporter for AutoCAD Civil 3D 2009 | Home

The VSP3D File Exporter from 3am Solutions is designed to provide a streamlined and intelligent method for the rapid transfer of civil design data from AutoCAD Civil 3D 2009 to Dynamite VSP running in Autodesk 3ds Max.

The VSP3D File Exporter is available as a FREE download from the 3am Solutions Online Community site.

The VSP3D File Format

VSP3D files feature a very compact binary file format intended to provide the most efficient method of transferring surface and featureline geometry to Dynamite VSP.

As much Intelligence as possible is retained from the Civil 3D model which offers many distinct advantages over traditional methods of transferring civil design data into 3ds Max:

  • The full hierarchy of AutoCAD Civil 3D corridors is retained in Dynamite VSP. Baselines, regions, surfaces, subassemblies, and featurelines can all be identified by name permanently within the Dynamite VSP visualisation environment.
  • VSP3D files may be dynamically linked to a Dynamite VSP based visualisation. By using unique name references on all imported objects, Dynamite VSP can react to changes in a referenced civil design when the linked VSP3D file is updated from AutoCAD Civil 3D.
  • Exported corridor surface data may be filtered by link code (usually "top"). This prevents unnecessary overloading of 3ds Max by automatically excluding unwanted sub-surface geometry from a visualisation scene.
  • Corridor Surface MappingExported surface data is optimised to ensure that commonly placed vertices are shared by adjacent faces/triangles instead of the traditional need for three independent vertices for every face/triangle in the surface. This can often reduce the number of vertices in a surface by a factor of 5 with no reduction in the accuracy or geometric shape of a surface.
  • Sophisticated alignment-aware texture mapping techniques provide full control over the way in which each individual subassembly or link is automatically textured in Dynamite VSP and 3ds Max.

Instructions for Use

Once installed, to access the VSP3D Exporter for AutoCAD Civil 3D 2009, select the Export to Dynamite VSP v3.6 (or higher) option from the AutoCAD Civil 3D 2009 General menu.
