Alignment Curves Oddly Displayed

I’m not sure if anyone's experienced this problem or not but when I look at an alignment that I’ve Data Referenced into my drawing in my Civil 3D 2011 the tangents and spirals display nicely but the curves don’t display correctly.  I’ve shown an example below.  As you can see, the curve doesn’t visually show as connecting to the spiral but the stationing (tick at the bottom) displays correctly on the theoretical alignment line.  I can still select the alignment to do C3D operations on it but the curves don’t show properly.  It’s quite annoying.


Oddly enough when I open the same drawing in my C3D 2012 it displays correctly so there must be some kind of C3D2011 setting or toggle that I’m missing.  Would anyone happen to know anything about this or how I can fix it?


Thanks,Civil 3D 2011 Curve Display Issue.png

You specify Data shortcut. So do you mean that it looks OK in the original drawing, but not in the host drawing of the d-ref? Are both drawings from the same template?

You mention 2012. You're not opening and saving in 2012 and then trying to work in 2011, are you? It's ok to just open read-only in 2012 to look at it; I presume that's what you are doing.

Credit where credit is due! Give kudos or accept as solution whenever you can.

Update:  I did a little more Google research and it turns out that it's not just a C3D issue but an AutoCAD arc issue.  Strangely enough when I set my VIEWRES to 20,000 it doesn't help at all but when I set my WHIPARC value to 0 instead of 1 it displays just fine now.  I'm not sure what the deal is with this as I've only ever used VIEWRES to control arc smoothness and never dealt with WHIPARC before.  Anyone know any potential problems with having my WHIPARC set to 0?
