This is a summary of several keyboard and mouse shortcuts available when using CityCAD.


If you hold the mouse cursor still over parts of the CityCAD window, tooltips will appear giving you information about what each thing is.

Keyboard shortcuts for selecting tools

Keyboard shortcuts can be used for selecting tools. Note that these shortcuts only work when you are working in the main display window and have just clicked in the main display window.

Opening Files

You can drag URB file icons from any directory into the CityCAD window to open them. You can also type Ctrl-O.

Navigating Around The City Model

When using most tools, you can orbit by clicking and dragging with the mouse wheel button. If you hold down Ctrl while doing this, then it will act like the grab tool.

Rotate City Items, Gridirons and Pasted Elements before Placing

If you are doing one of the following:

  • You have selected the City Item Tool and are about to place an item.
  • You are about to place a URB Sample File in the model.
  • You have just started a Paste command and are about to place the pasted elements.
  • You are about to place a block or gridiron from the Add Blocks panel.

Explode to Floor

To explode to the ground floor of a building block, select the block and type Ctrl-0

To explode to the first floor above the ground floor of a building block, select it and type Ctrl-1 for the first floor above ground, and so on up to the ninth floor.


  • To turn all snaps on/off, type Ctrl-Shift-S.
  • To turn drawing constraints on/off, type Ctrl-Shift-C.
  • To select default snaps, type Ctrl-Shift-D.
  • >To select narrow range snaps (smaller snap radii), type Ctrl-Shift-R.
  • To select snaps for tracing images, type Ctrl-I.
  • To select snaps for tracing dxf base maps, type Ctrl-D.

Moving Exploded Floors Up and Down

When a block is exploded and one or more floors are 'up in the air', and if the block is selected, then you can adjust the height of the blocks by holding down Ctrl and rolling the mouse wheel up and down.
