CIM allows certain functions to be executed immediately through keyboard shortcuts.

◈ CIM Learning Center website.

   Keyboard Shortcut [ F1 ] Opens the CIM Learning Center website.

 Message Window initialization

2. Workspace Exit/Save

CIM consists of a total of 9 Modes, including the Base Mode.

As each Mode is entered, the upper ribbon menu is reconfigured based on the features of each mode.

To enter each Mode, the user can click on the desired Mode in the Ribbon Menu.

Figure 1. Mode entry through Ribbon Menu

Figure 2. Mode OK / Mode Apply / Mode Cancel

Mode OK  : Keyboard Shortcut [ Alt + 8 ] Saves current mode and moves to parent mode.

Mode Apply  : Keyboard Shortcut [ Alt + 9 ] Saves current mode and remains in current working state.

Mode Cancel  : Keyboard Shortcut [ Alt + 0 ] Cancels the current progress and moves to parent mode.


When each corresponding Mode is entered, not only does the upper Ribbon Menu gets reconfigured, but also the Work screen changes to the corresponding Work Space.
The user can exit each Mode and return to the Base Mode by clicking on one of the options on the upper left corner of the screen (Mode OK/ Mode Apply/ Mode Cancel).

The following keyboard shortcuts are used for saving and exiting CIM programs as well as moving back and forth.

Program Off  : Keyboard Shortcut [ Alt + F4 ] Exits the program.

When using the main panel, you can conveniently run/stop the function by using the shortcut keys.

OK : Keyboard Shortcut [ Alt + Z

Apply : Keyboard Shortcut [ Alt + X

Cancel : Keyboard Shortcut [ Alt +  '  ]

Input window switching : Keyboard Shortcut [ Tab / Shift + Tab] The focus moves to the next / previous input window.

4. Adjusting View Options

When modeling in CIM, the user can use keyboard shortcuts to model efficiently.

The functions below work in the same way for both 3D (Base Mode etc.) and 2D (Rebar Draw Mode etc.) workscreens.

Show only  :  Keyboard Shortcut [ F2 ] Hides all objects except the selected object.

Hide only  :  Keyboard Shortcut[ Ctrl + F2 ] Hides the selected object.

Show All  :  Keyboard Shortcut [ Ctrl + A ] Shows all objects on the work screen.

Zoom Fit : Keyboard Shortcut [ Ctrl + F ] This feature optimizes the view by adjusting only the scale while maintaining the viewpoint direction.


Click on the mouse wheel for the View Option where the user can view objects from various angles including Top/Bottom.
The view that is provided here is automatically adjusted to include all objects on the screen where the user can zoom in and out by moving the mouse wheel up and down.

Top Snap / Front Snap / Side snap
: Keyboard Shortcut [T/F/S]  Pressing the T/F/S keys on the keyboard will activate Snap based on the
  Top / Front / Side planes, respectively.


The box shape in the lower right corner shows the status of the current view, the T / F / S  plane, and the status of the X / Y / Z axis.

Snap Hold
: Keyboard Shortcut  [Shift] While holding down the Shift button, the Snap will be locked to the moment
  it was pressed.


When this shortcut is executed, the snap is fixed and separated from the mouse movement.

View Point Hold
: Keyboard Shortcut
 [Ctrl]  While holding down the Ctrl button, the coordinates at the moment the
  button was pressed are fixed to the center of the object, and the object rotates around this center.


The keyboard shortcut [Ctrl + Wheel + Move] results in a rotation around the object with the cursor.
If the cursor is not above the object, the rotation occurs around the previous point of rotation.

Additionally, you can use shortcut keys to toggle specific options provided in the View Options on and off, or to switch between them.

Datum On/Off  : Keyboard Shortcut  [ Alt + D ] The user can turn the reference point on or off.

Perspective On/Off  : Keyboard Shortcut [ Alt + P]  If enabled, the model is made more prominent by applying a wider angle than the default angle.
