I have created a TIN surface from polyline contour data in Civil3D 2013. My file shows shows that the surface is present both in the Prospector and when I float over the surface and will preview. I assigned a style to the surface, which for my uses is displaying minors at 1' and majors at 10'. My problem is that the contours only display sometimes. That is to say, SOMETIMES I open the file and I can see the surface contours and other times it simply will not display them. There has been NO change to the layer (on, visible and not frozen) nor to the style (not assigned as not showing or any different color) between current and the time I used the file last. Occasionally, when I restart my machine, the contours will display for a few hours worth of work, but when I return the next day, or after a hang, restart my machine again, the contours simply will not show. If I add "show triangles" in the style definition, the triangels will show every time, but not the contours. This is SO frustrating.
In an effort to find some remedy an engineer firend suggested I changed my RAM from 2- 4GB DIMMs to 2- 8GB DIMMS giving me a total of 16GB of RAM, which I did, but it doesn't seem to have made any appreciable difference in performance and the contours still don't show. Does ANYONE have any ideas about why this may be occuring?
Thanks in advance
Solved! Go to Solution.
Do you have level of detail switched on (under view ribbon I think)?
Hey! I didn't know about that... That seems to have worked. I'll have to see if it sticks.
Thanks. I have been beating my head against the wall with this problem. I toggles off level of detail and it solved the problem right away.
