# 2.2 Change Menu

The Change Menu has all functions related to modifying objects that exist on the layout drawing.

  Properties - sets XTrackCAD into Describe mode. Whenever an object is clicked on while in this mode, the Properties dialog is opened. This dialog allows direct manipulation of settings such as the objects length, position or orientation. (Section 2.2.13).

  Select - sets XTrackCAD into Select mode. Whenever an object is clicked on while in this mode, this selection state of this object is reversed. If an object was unselected it becomes selected, and vice versa. To unselect all objects press the ESC key, use Deselect All from the Edit (Section 2.4) menu or Deselect All from the Pop-up menu (Section 3.4.1). (Section 2.2.16).

  Move - move selected object(s). (Section 2.2.9).

  Rotate - rotate selected object(s). (Section 2.2.15).

  Flip - turn selected object(s) over or around. (Section 2.2.6).

  Loosen Tracks - this command reverses the effect of Connect Two Tracks as applied to sectional track.

  Modify - modify an existing track, or lines. (Section 2.2.8).

  Join - connect two separate pieces of track or two lines. This command can be used to move one of the pieces of track to the endpoint of the other or to create a connection by laying a stretch of flex-track. (Section 2.2.7).

  Connect Two Tracks - creates a connection between track pieces with an option to slightly move the select piece(s) and the pieces they connect to. (Section 2.2.3).

  Split - the Split commands are used to divide up tracks (Section 2.2.17.1) or split draw objects (Section 2.2.17.3) or use a second Object to Trim (Section 2.2.17.4). The (Section 2.2.17.1) command can be used in one of two ways;

  - split a section of flex-track into two connected pieces at the point where a Left-Click is invoked or;
  - disconnect turnouts or sectional track pieces at their point of connection.
  Move Description - move the endpoint description of a track piece to another location. (Section 2.2.10).

  Raise/Lower Elevations - raise or lower elevation of selected tracks. (Section 2.2.14).

  Elevation - define an elevation at specified track location (Section 2.2.5).

  Profile - display the elevation profile of a definable stretch of track (Section 2.2.12).

  Clear Elevations - remove elevation parameters from selected track(s).

  Recompute Elevations - performs a global re-computation of dynamic elevations. It should not be necessary to issue this command as elevations are recomputed as required.

  Change Scale - change model scale and/or gauge of layout design. (Section 2.2.1)

  Convert - chnages fixed tracks (Straight, Curve, Joint, Bezier) into a Smooth Cornu or vice versa. (Section 2.2.4).
