Line Drawing
The Draw command is used to draw lines, arcs and other shapes.
These can be used to represent water edges, bridges and other scenic features. 
The Draw dialog allows you to choose various shapes (lines, arcs, circles or boxes).
Also, the Delete option allows you to delete lines from the current drawing.
The Color and Line Width can also be specified. -
Lines are created by Left-Dragging on the layout.
Shift-Left-Drag will use the End-Point of the previous line as the starting point.
-
Arcs are created in the same manner as curved tracks.
First select the beginning of the arc and drag to specify the beginning angle.
Release and created again to place the end of the arc.
-
Circles are created by selecting the center position and dragging to specify the radius.
-
Boxes are created by selecting one corner and dragging the opposite corner.
A box is composed of four lines which may be individually deleted.
-
Poly Lines are created by Left-Dragging, and a corner is placed when you release the Left mouse button. The Poly Line is finished by a Right-Click or by selecting another operation.
-
Filled Circles are created like Circles.
-
Filled Boxes are created like Boxes.
-
Polygons are created like Poly Lines.
-
Above moves the selected object to the top of the drawing order.
-
Below moves the selected object to the bottom of the drawing order.
-
Delete allows you to delete lines and arcs.
Note: Boxes are treated as 4 separate lines for Delete.
The line width is specified in pixels for the current drawing scale.
If you Zoom In or Out the lines will be drawn wider or narrower.
XTrkCad treats the segments created with one draw command as separate objects when deleting or selecting
objects.
These objects can be changed by the Modify Command:
-
The End-Points of a Line can be dragged to new positions.
A Box is treated as 4 Lines.
-
An Arc is modified in same manner as modifying a curved track.
-
Selecting a corner of a Poly Line, Filled Box or Polygon moves that corner to a new position, and if moved close to a neighboring corner will merge the two corners and delete the edge between them.
Selecting an edge will create a corner that can be dragged to a new position.
