Z Coordinates in AutoCAD 3D Tutorials

I. 3D Coordinates

Entering  3D  Cartesian  coordinates  (X,Y ,Z)  is  similar  to  entering  2D coordinates  (X,Y). In addition  to  specifying X  and  Y  values,  you specify  a  Z value.

1.  Open    a drawing with 3D objects and display in a 3D view.

2.    Type     3DPoly at the command prompt.

Command: 3DPOLY
Specify start point of polyline: 1,1,0
Specify endpoint of line or [Undo]: 1,2,1
Specify endpoint of line or [Undo]: 2,2,1
Specify endpoint of line or [Close/Undo]: 2,1,0
Specify endpoint of line or [Close/Undo]: 1,1,0

The result will be the following lines that are drawn in 3D:

With AutoTrack (polar tracking and object snap tracking), you can track in the Z direction as well as in the XY plane. Similarly, when Ortho mode is turned on, you can lock the cursor to the Z direction.

1.  Press     F11 or click OSnap Tracking on the status bar if it is not already on.

2.  Press     F10 or click Polar Tracking on the status bar if it is not already on.

3.  Draw    a line in the 3D view in the Z direction using tracking.

III. Move in Z Direction

1.  Open    a drawing with 3D objects in it.

2.    Type     MOVE at the command prompt.

Command: move
Select objects: pick object in 3D view
Select objects: press enter
Specify base point or displacement:
Specify second point of displacement or
<use first point as displacement>: 0,0,1 or use polar tracking to move the object.

Draws in 3D Z direction by filtering X and Y coordinates.

1.  Open    a drawing with 3D objects in it.

Z Coordinates in AutoCAD 3D-4Use the CIRCLE command and place it using 3D point filters (.xy)
Command: CIRCLE
Specify center point for circle or [3P/2P/Ttr (tan tan radius)]: .XY of pick endpoint to filter (need Z): 1
Specify radius of circle or [Diameter] <0.2500>: press enter

Z Coordinates in AutoCAD 3D-5V. Helix

Creates a 2D or 3D spiral.

1.  Begin     a new drawing.

2.    Choose   Draw, Helix.
or
3.    Type     HELIX at the command prompt.

Command: helix
Number of turns = 3.0000 Twist=CCW
Specify center point of base: pick point
Specify base radius or [Diameter] <1.0000>: enter or drag and pick
Specify top radius or [Diameter] <11.0776>: enter or drag and pick
Specify helix height or [Axis endpoint/Turns/turn
Height/tWist] <1.0000>: enter or drag and pick
