BRL-CAD's new website design uses lot of icons. It would be great if these icons have the look and feel of CAD/CAM in it.

So the task consists of making an icon set including icons for:

• All the menu buttons (About,Downloads,Documentation,Community, Blog, Gallery)
• Sign-Up & Log-In icons
• Major Social Media Icons

Few things to keep in mind:

• All icons should somehow adopt the look and feel of CAD.
• They all should be in PNG/AI/SVG format.
• The icons need not be complexed or textured, though long shadowed flat icons would be appreciated.
