A Rhino3D plugin sponsored by Nano3DTech.

Simply visit the plugin page. Then log in and push the install button in front of latest released version. Or alternatively, do these:

1. Use PackageManager command on Rhino3D commandline.
2. Search for plugin name i.e. BESO.
3. The plugin will be listed through the package manager UI.
4. Click the install button.

Once the plugin is installed, its commands can be accessed by typing the plugin name on command line. Start typing BESO on Rhino3D command line to auto complete the plugin commands.

This video demonstrates how to use the plugin command after installation:

• After the FEA for the original model, you have to close the CGX window to proceed to BESO.
• Finite elements are generated by SDFX package. There is a known issue: Megidd/Feather#2

An in-depth description of BESO and its capabilities are available on the wiki.

This plugin offers a BESOTopologyOptimization command to optimize usage process. Making sure your 3D model has maximum strength and minimum weight.

This command helps you optimize the toplogy of 3D model. You can keep the model strength while decreasing its weight. The finite element analysis - FEA - along with topology optimization are the technologies under the hood. FEA will be done according to user-selected loads and restraints. An optimized 3D model will be generated. Some elements of the original 3D model are removed without affecting the required strength.
