ZERO ELEVATION(STYLE OVERRIDE)

[ESchomberg]

Hey guys, this is somewhat a trivial question that I could dance around but would rather understand why it is not working correctly.

I am doing 2D drawings so I prefer all of my lines to be flat to avoid line-work and hatching issues. Normally I would complete my drawing, highlight the entire thing and flatten it all at once.

I then accidentally found that if you right click on "all points" then properties, then overrides; you can check the 0.00' elevation box and make all of your survey points 0.00' elevation at once. It even shows at the bottom of prospector that all of my survey points are at 0.00' elevation.

The problem is that I am still dealing with line work issues such as a line that should be dashed coming in solid. I then click on the line........properties and it shows the starting Z to be -9.99E+27. I am assuming that is some type of exponent value. If I flatten the line it then correctly shows up dashed. But why am I having to do that when I have my zero elevation override checked and all survey points show up a zero elevation.

Erik,

Why did you double-post?

Civil 3D Objects (COGO Points) and AutoCAD Objects (Lines) exist in the same drawing, but they don't play by the same rules.

There's a fella over on the Vanilla Forum that has the same question:

Cogo points have two elevations.  The database value is what you see in the point editor and the display value is what you get if you snap to the node in CAD.  The control for this is in the point style.

Users who typically do mainly 2d drafting will set all of their point styles to flatten.  Others, like me who do mostly 3d work use point styles set to display true elevation.

The override elevation in a point group is often used for surfaces and specialized labeling.  If you set the override to zero, and use that point group in a surface definition then all of the point elevations will be zero.  You can also create a separate elevation parameter for your points using an external data reference and then use that new elevation data instead of the normal values.

Steve, that was well said. Thank you.

Thanks Dave.  I've been watching some of your recent work and thinking that I need to step up my game a bit.

I'm sorry, I did not mean to double post. Sounds like a good reply just sounds a bit complicated. I need to re read tomorrow with a fresh mind. Thank you for the input. Will follow up.

I haven't looked at your drawing yet. But you can draw with OSNAPZ set to 1 and ELEV set to 0. You can set your point to import at 0: http://forums.autodesk.com/t5/autocad-civil-3d-general/insert-points-at-0-elevation/td-p/2603040
