Defining a new UCS

UCS manager

The UCS manager can be used to define completely a new user co-ordinate system if the user knows numerically the parameters of the system. That means, if the user knows the exact global co-ordinates of the UCS’s origin and the exact direction vectors of individual UCS’s axes. Otherwise, the UCS manager is used to create a new UCS instance, and one of numerous UCS-modifying functions is later applied to specify the origin and orientation of the UCS exes.

The procedure for the definition of a new UCS from within the UCS manager

  1. Open the UCS manager.

  2. Click button [New]. This creates a copy of the current UCS.

  3. Click button [Edit] to adjust parameters of the new UCS.

  4. Type in the required values for the origin of the UCS and for direction of its axes.

  5. Close the editing dialogue.

  6. Close the UCS manager.

The procedure for the definition of a new UCS parameters using a menu/toolbar function

  1. Open submenu UCS (either in menu Tools > UCS, or under button [Setting of UCS for active view] (image\Icon_UCS_submenu.gif) on toolbar View).

  2. Select the required way of definition.

  3. If necessary, input required parameters (i.e. required point or points).

  4. Once more open submenu UCS (either in menu Tools > UCS, or under button [Setting of UCS for active view] (image\Icon_UCS_submenu.gif) on toolbar View).

  5. Select function Store the current UCS (image\Icon_UCS_Store.gif).

  6. Type the name of the UCS and confirm with [OK].

  7. That’s it. A new UCS is defined and will appear in the UCS manager.
