how do I clean up the topography lines In elevation view, as you can see in the atached image topography lines are shown and they look messy . I only need to show the ground line . I had to create a mask region to hide the lines and draw only one ground line but I feel this is inaccurate way to resolve this. Any better ideas out there ?
I hope there was a better solution. but the answer is no. I did the same using mask region or a region to cover messy lines in elevations/ sections. Toposurface has been a weak spot for years. still no sign of improvement.
There are 2 things you can do to make this look better.
The first thing is to make sure the projection plane of the elevation is located inside the boundary of the toposurface so when the elevation is projected the toposurface is "cut" this will give a much darker line along the edge of the topography and give it some poche below the line making the ground line read better.
The other thing you can do is turn off the primary and secondary contour lines in the visibility and graphics of the elevation view. This will remove the interior lines you are seeing on the toposurface.
