Surface - Quick Contours and Regular - Missing Contours

    I have noticed that when you use the quick contours or the regular create contours, the command will sometimes miss contours that are part of the surface as a breakline. The surface is correct but the visual representation of surface is "off". Is there a way to force this to be correct? Or is my best option to copy these breakline and add it to the data contours. I would prefer not to have to do this because then I will have to remember to delete/alter this if the design changes but I do understand that I may have to.

     

    Is there a way to force business center to trace/copy breaklines that are a constant elevation? This might ensure that all of the proper breaklines show up as contours.

    I just mocked up a surface where the highest contour gives a "Plateau" and the Contours generated along the Plateau edge OK and along all other Breaklines that I drew at specific elevations - so this may be data specific as an issue here Pat - could you share the fie with me so I can take a deeper look. I was thinking that maybe if the top elevation was 108 and it flat tops or flat bottoms at that elevation that maybe the last contour was not getting created - but that doesnt appear to be the case or we have had this reported and fixed it already which is also possible.

     

    Please share a Surface project where you are seeing this issue and I will take a look. If for example the data has been converted from Metric to Feet, what was a 108 contour may now be 107.999999 or something and that may cause the 108' contour not to draw - maybe one of the Data Prep Tools is doing that to the data so while it may show as 108 maybe at 5 or 6 decimal places it isnt 108 or something like that.
