Coummunity Bonding Period

• Set up the Development log
• Set up the development environment such as OS.
• Start to look at the different potential libraries code base.
• Discuss with mentors which external library to choose.

• Had four of my wisdom teeth extracted. The progress for the following week may be slow due to teeth extraction.

May 18th

• Rest.

May 19th

• Looking at Coin3D/Dime code base, a possible library for DXF import/export.
  • It has no external dependency.
  • It supports all past and should support future version of DXF format.
  • It compiles on Windows, Linux, MacOS, etc.
  • But it only loads DXF files into Dime object hierarchies and saves Dime object hierarchies as files conforming to DXF format.
  • Seems only support 3D.

May 20th

• Looking at BRL-CAD DXF import/export code. Trying to understand how it works and see if it is suitable for OpenSCAD.
  • It converts DXF format to .g and .g to DXF which is a BRL-CAD format.

May 21th

• QCAD is using a nice DXF library, dxflib, but it only supports 2D which is not ideal since OpenSCAD is already supporting 2D.
