Icons are images used to represent custom tools, tasks, workflows, and context menu items. The icons can be standard MicroStation PowerDraft icons that you can create or customize. They can be Bitmap images or icons imported from ICO, DLL, EXE, DGN, or DGNLib files.
If you used earlier editions of MicroStation PowerDraft to customize icons, you can import your customizations into this edition. Your earlier icon customizations were stored in user interface modification files (MDL resource files).
