Q - question

Easily connect 3D points in Civil 3D.

A - answer AutoCAD Civil 3D allows (anywhere it asks for a coordinate) to use a transparent command returning the coordinate from the point number (PN) or from the point name (PA).

E.g. if you have the following points in the points list of your drawing/project:


You can e.g. draw a line from the 2nd to the 3rd point with:

_LINE 'PN 12 [esc] 'PA point13 [esc] [enter]
But you can also create quickly a 3D polyline going through (connecting) the whole series of points - with a single simple command:
_3DPOLY 'PN 11-15 [esc] [enter]
Civil will even skip possible missing points in the specified series (from-to).
