How do I draw 2D lines from points? What setting do I need to change? I want to drawin glines using the node as a grip but I do not want them to have z coordinates.
If you are talking about just drawing manually, try setting the OSNAPZ sysvar. (I can't remember if it is 0 or 1, but the opposite of whatever it is currently set at!)
Credit where credit is due! Give kudos or accept as solution whenever you can.
OSnapZ Follow the link,
You might also want to use OSNAPOVERRIDE
Set OSNAPOVERRIDE to 1. You then cannot pick a point that does not conform to your running osnaps.
Remember to set it to 0 after you finish or things might get confusing.
In your point style settings you can specifiy flatten points to elevation and specify 0 as the elevation. This is what we do and it works great. It doesn't change the Z value of the survey point itself it merely place thes survey point at 0 elevation. Personally I cannot stand drawining in 3d or obtaining 3d distances when trying to obtain a simple horizontal distance.

Until we got a 3rd party app, SmartDraft, that will give 2D dist an bearing between point even when 3D. I always used CgSList. It gives both horizontal and vertical distances as well as the slope. I wrote a macro that defaulted to points. Your method is also correct. I just wanted to point out options.
Options - Drafting - Object Snap Options.
Check the box - Replace Z value with current elevation.
