How To Input North, East, and Height Coordinates Into AutoCAD

It is very easy to input North, East, and Height coordinates into AutoCAD. Let me first give you some examples. Then I will explain:

Draw a line


First, draw a line from N 1000, E 6000, HEIGHT 48 to N 7000, E 9000, HEIGHT 54
Type the following (without the "=" parts):

===============================================
LINE
6000,1000,48
9000,7000,54

===============================================

Insert a point


Next, insert a at N 1500, E 6500, HEIGHT 52
Type the following (without the "=" parts):

===============================================
POINT
6500,1500,52
===============================================

Note that the normal mode of AutoCAD is to use X,Y coordinates where X is East (left) and Y is North (up). So we input N, E, Z (HEIGHT) by switching the N and the E around. If you are inputting a lot of points, you can use a lisp routine like this free one or a specialized version of AutoCAD like Map or Civil 3D.

There may be special conditions that are giving you fits. If you are having troubles or if you have any questions about inputting NORTH, EAST, and HEIGHT coordinates into AutoCAD, leave me a comment and I will try to clarify.

I m using AutoCAD 2008 but i no longer want 2 have ucs coordinates xyz i just want 2 change them 2 North East so is it possible 2 change ur ucs coordinate so when i use id command i can get the coordinates in north east instead of xy coordinates so help me in this if u can?

I'm not aware of a way to switch the reporting of your coordinates using AutoCAD. Sorry.

Can we keep the height zero..since its 2D?

Thomas Gail Haws said...

Yes, you can use 0 for z or omit the z when you enter coordinates. Like this:

23,38

Instead of

23,38,0

or

23,38,82

Warning: Make sure that ELEVATION is set to 0 by typing ELEVATION at the command prompt.

In electrical it Written on A drawing Transformer A N 2786930 & E 418638 likewise many points written but i Do Not Understand What Are These Different Points Written With N & E Nos.. How Do i prepare if i Have to.. From Starting to Ending I use Autocad 2010 2d

You can add a LEADER or an MLEADER, then use the ID command with OSNAPS to get the coordinates of a point, then use Copy and Paste to put those coordinates into the LEADER or MLEADER.

If this is too tedious for you, and you want an automated way to do it, you can find and load a lisp routine. You may be interested in the one I wrote here: http://autocad.wikia.com/wiki/Curve_table_creator_(AutoLISP_application) or at my web site http://www.hawsedc.com/gnu/curvesauto

some of my points come in bunched together in the same location...not sure why?

I think you probably have a running OSNAP set. Try checking your running osnaps or toggling them off.
