OS: Mac OSX 10.12 for Intel CPUS, 11 for ARM CPUs or higher.

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 and choos the downloaded ZIP file. Do not unzip the file prior to installation.

Enabling the addon

Usage:

Select the objects to be exported and File->Export->Export IGES. It is advisable to export objects separately in batch mode. 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"
Up axis (default Z Up)
Forward axis (default Y forward)
Apply Modifiers (default on)

Limitation:

There should be only one subdiv modifier and the subdiv modifier should be the last in the stack. The output might not match the shape if there are muliple subdiv modifiers and/or such subdiv modifer is not the last one. In such cases, apply such subdiv modifiers manually.
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.
