时不时稍微站远一点看看自己的工作，能更好地把握节奏，明确方向。防止钻在一个细节里闷头苦坐。

• HMI: Photoshop mock-up of the three main function tab → make slide to show its function.
• 3D model: the current fbx file is too large (900mb), make it smaller (100~200mb)

• Sort out alert icons and status icons, save them in two separate files.
• Looking for method to reduce 3dm file size:
  • the original jt file is about 300 MB, and after being converted to 3dm file, it became 1.5 GB
  • Use "Audit3dmFile" command to check what is contributing to the size: there are too many objects (more than 2 thousands)
  • First, try to simplify the mesh. ←- looks like it doesn't work. (ref: custom mesh setting?)
  • Next, empty the objects inside of the excavator.
• UI: alert bar
  • One row: left is alert icon, right is alert message.
  • Two rows: top is alert icon, bottom is alert message.
