I imported contours from a shp file into a metric drawing. The elevations are in meters. I create a surface from the contours. The elevations are in feet. My brain is tired. How do I create a metric surface?

Thank you for your efforts. I edited the units in the projection file (changed METERS to FEET) and repeated my surface process. (SHP import, save, attach to new drawing, query altered elements by object data, and create surface.) The surface is in meters, my drawing is in meters, and once again all is right with the world. Thanks again.
I would try starting the Civil 3D Metric program and use a metric template to create the surface in the correct coord sys...Never made one before...
No labels yet. I'm getting elevations from the surface tooltips.
I'm using a metric template. For about a minute I thought I could trick the program by using an imperial template, creating the surface, and then switching to metric units but to no avail. My surface elevations changed when i changed the units.
I've never checked this but was the shape file defined in Imperial units?
Just to confirm - you've started from a metric template, and imported a shape file which produces polyline contours. The contours are at metric intervals. When you create a surface from those contours that surface reports elevations in feet.
Do I have it correct?

That was affirmative to your summary. The projection file specifies metric.
Wild guess but have you checked your surface style. I had a similar problem with points and it turned out that the point style specified feet even though the drawing was metric. I wasn't up on styles and had just copied the imperial point style in the metric drawing.
Also. Be aware that normally Civil 3D does not do Vertical Transformations!
Where exactly does the surface style specify vertical units?
