Description:

Export IGES Addon for Blender creates subdivision limit surfaces and saves it as IGES file.

From Blender using the default options.

System requirements:

OS: Windows 10 64bit with VC++ runtime 2017 or above.

OS: Linux 64 with the following dependencies. 

libstdc++.so.6 => /lib/x86_64-linux-gnu/libstdc++.so.6 
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6
libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6

Should work with Blender 2.82 and above. Tested on Ubuntu 20.04 LTS.

Installation:

Install the downloaded addon using Edit->Preferences->Install

Enabling the addon

Usage:

Select the objects to be exported and File->Export->Export IGES. Please ensure that all modifers except subdivision, are applied to the mesh objects before exporting. Also, it is advisable to export objects separately. so that it can be managed better in CAD systems.

Export Options:

  • Export slected only exports selected objects.
  • Subdivision level: 1, 2, or 3. Default value is 2.
  • Batch Mode: Saves objects as individual IGES files. The name of the file will be in the format "name_objectname.igs"

Limitation:

  • Tangency at the vertices of odd variance may not be sufficient with low subdivision level.
  • SubDivison limit surface will conicide with the border edges and corners.
