create 0 elev polyline by point no. range?

The command for Creating Lines by Specifying a Range of Point Numbers makes 3D line segments. Is there an option to make a zero elevation polyline running through cogo points that are 3D (the 3D line segments occur even if the cogo points are set to flatten elevation)?

Change your OSNAPZ to 1.

Select Cogo points in draw order desired;
Access the Edit button / List Points;
Show only the columns of X and Y (East and North);
Copies columns to the clipboard;
Open Notepad;
Paste the data;
Format columns to stay in X, Y
The first line includes the Pline command, as an example:




Copy the list of items on the command line, and this will generate a polyline.

I see a couple ways to do this..


1. Use the Civil 3D command and then run "Flatten" on the resulting polyline

2. Use a standard AutoCAD "PLine" command.

    a. start the pline command

    b. When prompted for the first point enter: 'PN and then enter the point number of the first point, and hit Escape to get back to the polyline prompt

    c. When prompted for the next point, enter 'PN again and then enter the range of points you want the polyline to use. Hit Escape again to get back the the polyline prompt to finish the command.


The polyline will pick up the elevation of the first point, but you could just move it down to 0. An alternative would be use the .xy filter on the first point and instead of typing the point number select the point with the Node object snap and enter 0 for the elevation

The OSNAPZ toggle doesn't affect the command  -  Line by Point # Range ( _LINE Specify first point: 'PN.) I get 3D line segments regardless of whether or not Point Style 3D Geometry is set to Flatten Points to Elevation or Use Point Elevation.

Lines can have different Z values on each end, use a polyline instead of a line. PL to start command, then type 'PN to get into the point number transparent command and just enter your point numbers or ranges.
