In Civil 3D 2009, any surface which uses a style under which only one minor contour would show for the entire surface, no contours are shown.

This is very difficult to explain verbally, but the image below illustrates the problem.

Workarounds:
Create a temporary style which shows major contours at the interval that you would typically show minor coutours with. Make those major contours the same color/layer/linetype as your regular style’s minor contours. Apply the new temporary style to the problematic surface.

Since rolling out 2009 to a large userbase, we have encountered several drawing files which contain specific layouts within which any viewport will not show filled 2d solids properly. This behavior seems to be specific to AutoCAD 2009. The same drawing files behave as expected in AutoCAD 2008 (and, presumably, earlier releases).

Although fillmode is turned on, a viewport within an affected layout will show 2d solids like so:

Of note:

• fillmode is set to 1
• All viewports are set to 2d wireframe / hideplot is turned off in all of the viewports
• I do have raster design 2009 installed. Neither the “filled object hotfix” nor SP1 corrected the problem
• An example drawing can be found here: http://www.texupport.net/acad_examples/fillmode.dwg

Workarounds: Recreate the entire layout, including the viewports and any paperspace annotation.

Starting with AutoCAD 2009, the most recently used files list is designed to list both DWG and DST files.  Unfortunately, once nine (cumulative) DST files have been opened by one user, then the most recently used documents list will no longer contain drawing files. 

Workarounds:
I wrote this command to completely reset the MRUF list.  This will remove all entries from the list.  Over time, be prepared for it to be populated by nine DST files again.  When that happens and it gets to be too annoying, simply re-run the command.  (Note: I’ll add the LSP file to the downloads section ASAP.)
