Horizontal Ordinates

With MicroStation AccuDraw the user is limited to X-Y (rectangular) or Distance-Direction (polar) coordinate systems. With Civil AccuDraw, the user may define an ordinates system from virtually any combination of the following ordinates.

Note: Some combinations are disallowed simply because they do not make sense. For example: Dx - Dx

X: Absolute value of X coordinate

Y: Absolute value of Y coordinate

Dx: Delta X (change in X) from compass origin

Dy: Delta Y (change in Y) from compass origin

Distance: Horizontal distance from the compass origin

Direction: Direction (as per Settings > Design Settings > Angle Readout) from the compass origin.

Station: The distance measured along an element. Any graphic linear element may be used. Use the Origin shortcut to choose the element.

Offset: The distance measured perpendicular from an element. Any graphic linear element may be used. Use the Origin shortcut to choose the element.

Sample Systems

Some examples of ordinate systems that may be useful:

X-Y
Dx-Dy from same origin
Dx-Dy from different origin
Distance-Direction from same origin
Distance-Direction from different origins
Distance-Distance
Station-Offset from same or different base elements
Offset-Offset
Direction-Offset
Distance Station
