CAD software 3D Polyline 4 Command line: 3DPOLY

3D polyline consists of connected straight line segments. Each vertex of 3D polyline can have different heights (Z-direction coordinate). In contrast to a polyline, when drawing 3D polyline, the functions of constructing arc segments and changing the line width are not supported.

Command options


Deletes the last segment created.


Closes the 3D polyline by a line segment.

The option is available when the third point is specified.

Command prompts:

Specify the point:

Assign point 1.

Next point or [Undo]:

Assign point 2.

Next point or [Undo]:

Assign point 3

Next point or [Close/Undo]:

After entering the last point, press ENTER to close the command.

Created 3D polylines can be edited by PEDIT command, as well as with help of custom and multifunctional grips. Command Split converts a polyline into separate segments or arcs.

After constructing 3D polyline, the Vertex field in the Properties window becomes available; there it is possible to select a particular vertex of 3D polyline (in a graphic area it is highlighted) and set the value of its Z-direction coordinate.
