When you open your newly install SoldiWork, I will suggest you go to customization tab to utilize all the hotkey and shortcut tabs. In this way, you could maximize the efficiency of building model. Lets slice this topics into several section to increase the efficiency of this tutorial.
Important hotkey
| Hotkey | Function |
| S | Open shortcut tab |
| I | line |
| Q | measuring tool |
| E | smart dimension |
| shift + T | show all axis |
| Left Ctrl + S | Save As |
Customize your shortcut menu
While you press s, you will open this shortcut menu that will show some options that you might need. This menu is fully customizable, just got to the top of control panel and click the setting tab for customization. Remember that while you open sketch windows, you will have different shortcut menu, so please setup different menu for your own reference.

Utilize the shortcuts and hotkey not only increase your production speed but also make you look like a professional engineer!
