Why use a tool like VeSys Harness when the 3D MCAD systems have their own harness drawing tools?  The reason for this is that 3D MCAD systems harness tools have limited capabilities especially when it comes to creating manufacturing harness drawings, often OEM's throw an MCAD drawing over to the wire harness manufacturer who then redraw this in a tool like VeSys Harness.


What is VeSys' current capability?  With VeSys Design it is possible to send Wire Data into any of the popular 3D MCAD systems a common problem is then how to get the flattened harness back into VeSys Harness?  This document outlines a workaround that will help in creating a harness based on the 3D model, although not an automated process this should be helpful.


Unfortunately none of the 3D MCAD systems export geometry data that can be used by VeSys to create a harness drawing (VeSys has the ability to draw a harness from a data file for example hxf or dsi files).  The process is fairly simple:


  1. Flatten the harness in the MCAD system.
  2. Export this drawing in either DWG or DXF format.
  3. Open this drawing in VeSys Harness, it is advisable to move all of these objects onto a dedicated layer so that removal of these objects at a later date is easier.
  4. In VeSys Harness enable the 'Create Multiple Bundles with the Insert Bundle Command' from the 'Harness Tools -> Harness Options -> Harness' tab.
  5. Enable the 'Object Snap' so that VeSys will autosnap to the ends of the lines.
  6. Trace over the flattened 2D Harness using VeSys Bundles.


As was mentioned this is a manual process but there are some slight benefits, one of which is (depending on the 3D CAD system) that it might be slightly quicker to create the harness in the 3D model because corners could be cut for example splices would not need to be placed.
