Drape Image and Surface Problems

[Anonymous]

Hey guys,
Please forgive me, I'm quite new to Civil 3D. I have been having 2 issues I am hoping to get a hand with. The first is when draping an image onto a surface. We have 3 machines at work with Civil 3D on them (all users are as new as I am). One of my coworkers was draping an image on a surface and everytime he did the image would show up rotated 90 degrees counter clockwise. It showed up this way on one of the other machines which is identical to mine, but showed up properly on mine. We have tried recreating the surface from scratch, draping the images from different machines to start and resetting Civil 3D to it's original settings. Nothing has seemed to make a difference.

The other question I had concerned 2D lines or parcels on a 3D surface. Is there an easy way to "drape" a bunch of 2D lines or parcels onto a surface so when you show it in 3D, each 2D line sits on surface and/or gets the elevation level of that surface for the corresponding x,y point?

Thanks in advance,
Ben

Good Day All

I also have the same issue

we are about to purchase c3d but this problem is holding us

up as this feature is critical.

thanks jim

Hi benklepacki-

Although I do not have an answer for your drapping images issue at this time, I do have a suggestion for your second question. You can convert your 2D polylines to feature lines and have the feature lines pull the elevations from your surface resulting in something like this:

Hope this helps!

Seth,

Thank you very much, I will certainly try that!

Hello

I have similar problems, just it makes a mirror drape. I tried mirror image first, but the result was the same.

Which coordinate system are you using?

Hi,

I've had the same problem. The "solution" that works for me is to turn off the hardware acceleration.

Hope i helps

There was a discussion on these boards about this issue a while ago, started by someone from South Africa. I think it involved draping images for southern hemisphere on a surface that ended up being flipped. I do not remember what the resolution was, but I hope you can find the post if you search these boards.
