22-3. 3D Relative Rectangular Coordinates
How to Draw inwards Three-dimensional Space inwards AutoCAD
Command is entered on the form @X,Y,Z afterward the ascendence trouble you lot desire to draw.
Look at the moving-picture demonstrate above. To depict a trouble inwards 3D Space is necessary to specify the Coordinates inwards the next way.
- - Click on the Isometric push clit to switch to 3D sentiment (toolbar View)
- - To gear upwards the indicate T1 is needed: a click of a push clit LINE
- - Type 5,4,3 (X, Y, Z coordinates) fourth dimension indicate T1 positioned inwards 3D infinite past times planes that nosotros accept set. These coordinates are gear upwards past times Absolute rectangular coordinates.
- - To buy the farm on drawing a trouble that is positioned inwards T2 using rectangular coordinates relative to the Command Line box, type @ 7,4,5 (@ X, Y, Z coordinates of the indicate T2).
What did nosotros do?
We were at the indicate T1 (no affair how nosotros got into it). Used Rectangular Coordinates are Relative to buy the farm on to depict a trouble to the indicate T2. Using the @ sign is Relatively Coordinates (as inwards 2D). In this illustration nosotros write @ 7,4,5 which agency that nosotros tin rank the axe motility from indicate T1 (draw lines) on the X axis for the seven units, the Y axis for iv units as well as the Z axis past times v units.
Notice as well as remember: 3D rectangular coordinates of the relative benefits from the starting indicate where nosotros are as well as nosotros purpose the @ sign.
To download my actual appearance this DWG file.
So the sequence of commands equally follows:
Command: _line [click on the push clit to depict the trouble LINE]
Specify get-go point: 5,4,3 [setting upwards the get-go indicate T1 - starting X = 5, Y = Z = iv as well as iii - these are the absolute coordinates, but nosotros are inwards 3D]
Specify adjacent indicate or [Undo]: @ 7,4,5 [second gear upwards indicate T2 - @ = sign for the relative coordinates, X = 7, Y = Z = iv as well as v - these are the relative coordinates]
