AutoCAD Civil 3D

[#1]

Hi Brian and Shawn-

I apologize as I should have been more clear. The issue stated in the first post is a spearate issue from the second one stated in post #6 of this thread. The PNG files provided by Shawn illustrate a surface difference that is caused by LEVELOFDETAIL, I confirmed this on my machine. The first post issue with the colors of the style, you are correct, that is a known issue that Development is looking into.

Again I apologize for the confusion.

Have a great weekend!!

Seth, I just want to be clear.  Both issues still remain.  See pic in post 8.  I understand the 'level of detail' now, and contours did adjust, but that didn't fix the issue of surface creation from 'Ground' only Classification.  Brian's post clearly states this too.  The classifications are no longer recognized.

I look forward to a fix for both issues.

Thanks, Shawn

Hi Shawn-

So this is what I tested:

In 2011 I took the LAS file you sent me, created the ISD, then created the surface from all the points in the ISD and did not specify ground only.

in 2013 I repeated the same exact steps and compared the results, they were exactly the same. I did this to rule out any possible surface creation issue as the description on post #6 eluded to.

So back to the original style issue, the fact that they are all the same color and the classifications seem to be incorrect compared to 2013 is causing the surface creation issue as a byproduct. Are you still getting an incorrect surface creation when you build the surface from all the points?

Seems to be confusion with this matter.  2011 is fine.  2013 in NOT.  See comparison below.

Turn off all point classification EXCEPT ground in 2011 and right click the surface and rebuild.  The contours are nice and clean.  Turn back on all lidar classifications, right click the surface and rebuild and you'll see abnormal contours from tree canopy, houses and such.  All point classification colors are being recognized just fine.

Turn off all point classification EXCEPT ground in 2013 and right click the surface and rebuild.  The contours are abnormal.  Turn back on all lidar classifications, right click the surface and rebuild and the contours are still abnormal.  Its the same either way.  The classifications in 2013 are not being recognized in color or surface creation when classifications are checked on or off. Thus, giving us a useless surface to do any type of surface analysis.

I suppose the current work around would be to create the surface in 2012 and then data reference it into your 2013 drawings, assuming of course you have access to the 2012 version of Civil 3D.

Pretty terrible work around though.

Basically no point having point clouds in Civil 3D 2013 if you can't use the classifications to filter out ground points in las files.

Surprised this wasnt fixed as part of service pack 1!!

There are other point cloud files other then .las but I agree, if you are using classified .las files, they are pretty useless in Civil 3D 2013. Perhaps Autodesk has something up their sleeve. We can always hope.

Any word on if/when Autodesk is fixing the Point Cloud issue in 2013?  I just tried again with service pack 1 installed and issue remains.  Classifications aren't recognized and surface is still whacked with only 'Ground' Classification toggled.

The only thing I know to do at this time is generate my surface in 2011, export Surface landxml, then import it in 2013.

Hopefully Autodesk will provide some news.
