My contour lines below 0'-0" do not show up in any view. The surface is modeled correctly, but all contour lines below 0' do not show up in any views. I have never had an issue with this in any previous version of Revit.

I'm continuing to look for a solution, but since it's in all views, even 3D views, it seems like it's a bug (maybe a new feature, but a rather pointless one, if so).

I don't have any scope boxes on, I've tried adjusting the view range on the plan views. It's a residential project and we typically set the first floor height at 0'-0" for a residential project, that's why some of the grade is below 0'-0".

99.99% sure it is a user error of some sort.  Do you have imported CAD?

If the surface is modeled correctly, you had the countor lines at some point in time assuming you created them from scratch.

Goto a 3D view and do a zoom E.

I created the topo from a cad file. If I move the topo up so that all points are above 0'-0" all the contour lines appear. As soon as it moves down to where I need it to be, the lines below 0'-0" dissappear. I did a zoom extents to humor you, it didn't change anything.

I started a new project, re-created the topo again. The topo lines dissappear as soon as they are at or below 0'-0".

Remove the CAD file from your view.  It is either that or another enity like a floor that is hiding your lines.

The cad files were not visible, I've since deleted them and purged them. The contours still don't show up. My coworker is having the same issue on the project she is working on.

Perhaps, there is a maintenance update that we haven't installed yet, but it seems to be a flaw with 2017. Thankfully, it isn't critical for the time being.

Thanks anyway

I am also having this problem and I have never had it before, it seems like a 2017 glitch.  I drew my topo plan myself and the file is empty (no imports, etc.), I just started the drawing to see how much of a slope we are dealing with on site.

In my case it was primary and secondary contour lines that would show up above the 0' line, and strangely ONLY the (blue) primary contour lines showed up below the 0'.

WORK AROUND:  I changed the spacing of my (blue) primary contour lines closer together (to the spacing of the secondary contour lines).  This worked for me.   I can no longer can differentiate between primary and secondary contours, but it is better than nothing.  At least I have contours all the way down the slope, including beyond the 0' level where the house is.
