18-3. Sec Coordinates - Relative Rectangular Coordinates
AutoCAD RELATIVE Rectangular Coordinate System
In the pic inwards a higher house you lot run into what it looks similar the drawing Coordinate System amongst Relative Coordinates as well as Quadrants.
Relative Rectangular Coordinates are points that are located at or therefore distance from the root to a indicate where nosotros are right away as well as brand the intersection of axes X as well as Y.
UCS us tin hold upward located anywhere inwards this instance the drawing using the relative coordinates of all because it is of import to indicate at where you lot currently are.
When working amongst relative coordinates is an of import initial quadrant for the electrical flow indicate (the intersection of the coordinates) which is currently located as well as it is a starting indicate from which nosotros start. QUADRANT hold off inwards relation to the indicate where nosotros are.
Given that relatively coordinate organization based on the X, Y coordinates from the starting indicate of the electrical flow indicate inwards which nosotros uncovering ourselves therefore nosotros accept this chance to operate the organization to purpose the X as well as Y coordinates for a ready of points on the desktop.
IMPORTANT! Remember that inwards dealing amongst Relative Coordinates are ever start from the indicate at which you lot are, wherever was placed on the UCS. So nosotros ever X = 0 as well as y = 0 equally a starting point.
While entering the coordinates of the offset to move into the coordinates X as well as Y coordinates as well as then, they are separated yesteryear a comma.
Before drawing you lot must run the ascendancy that nosotros desire to describe a Line or Polyline, etc. .. as well as therefore create upward one's heed the coordinates of which are the intersection of X as well as Y axis but inscribed amongst the @ sign (ET) inwards front end of the coordinates.
This character @ type substitution combination (AltGr+V or Alt+64 on the numeric keypad). example: (@50,35)

EXAMPLE 1
See an instance of the Relative Coordinates. An of import @ sign, because it determines that the starting indicate where nosotros are.
Command: LINE
Specify offset point: 10,10 [set the starting indicate of using the absolute coordinate system]
Specify side yesteryear side indicate or [Undo]: @ 10,0 [is at indicate 1, inwards paragraph 1, type @, as well as coordinates amongst AutoCAD our seat inwards the indicate 2]
Specify side yesteryear side indicate or [Undo]: @ 0,5 [found inwards article 2, paragraph two Enter the coordinates amongst @ as well as AutoCAD positioned us to indicate 3]
Specify side yesteryear side indicate or [Close / Undo]: @ -5,5 [found inwards article 3, paragraph 3, type inwards the coordinates amongst @ as well as AutoCAD our seat inwards indicate 4]
Specify side yesteryear side indicate or [Close / Undo]: @ -5,0 [is at indicate 4, inwards paragraph iv Enter coordinates amongst @ as well as AutoCAD our seat inwards the indicate 5]
Specify side yesteryear side indicate or [Close / Undo]: @ 0, -10 [found inwards article 5, paragraph five Enter the coordinates amongst @ as well as AutoCAD our seat inwards indicate 6, ie indicate 1]
Specify side yesteryear side indicate or [Close / Undo]: ESCAPE (ESC) completion of drawing

This instance inwards a higher house nosotros tin describe amongst the mouse using the ORTHO mode but amongst the additional entry of line of piece of work length.
- - switched business office push for ORTHO mode
- - Running the Line
- - determining the starting indicate of 10,10 [Item 1]
- - is at indicate 1, the mouse EAST create upward one's heed the administration as well as therefore inwards the ascendancy line of piece of work prompt yesteryear entering x [item 2]
- - Located inwards department 2, create upward one's heed the administration of the mouse as well as therefore NORTH ascendancy line of piece of work prompt yesteryear entering five [item 3]
- - is at indicate three (ORTHO trend does non allow drawing diagonal lines (although nosotros tin click somewhere diagonally), therefore nosotros purpose the relative coordinates, the starting indicate for us is right away at indicate 3, equally nosotros move into relative coordinates), type the ascendancy line of piece of work prompt relative coordinate @ - 5,5
- - is at indicate 4, the mouse create upward one's heed the administration of WEST as well as therefore type five [item 5]
- - is at indicate 5, the mouse create upward one's heed the administration of South as well as therefore type x [item 6]
EXAMPLE 2
We are at a indicate on the desktop as well as non know that nosotros are the coordinates of that point. It does non matter. Using Relative Coordinates, nosotros tin describe a line of piece of work amongst no work equally nosotros want.
Command:
Command: _line Specify offset point: [the offset indicate nosotros possess got determined the click of the mouse]
Specify side yesteryear side indicate or [Undo]: @ 7,7 [X = 7, Y = seven way that nosotros possess got the X as well as Y switch seven units from the starting indicate for which nosotros create non know the coordinates unless seat ourselves at the indicate as well as the condition of the View toolbar are the coordinates. ]
T1 = Start
T2 = End
