While DeclaraCAD itself is written entirely by CodeLV it is made possible because of the work of many others.

I would like to thank the developers of the following libraries for their efforts and for making their projects open source:

• Opencascade - CAD Kernel
• pyOCCT - Python wrapper to Opencascade libraries
• enaml - Declarative engine and UI wrapper
• pySMESH - SMESH Meshing framework wrapper
• python-occ - Early versions of DeclaraCAD used python-occ

And many others which support the packaging and dependencies of these...

Thank you! Your efforts are much appreciated!
