Hi, I have problem to solve, which involve many differents question.
I want to do a simple thing : drap a ortho-photo on surface generated from contour line.
First thing, I need the basic terrain. I did import my contour line in a new draw, using the import map feature. I then saved the draw under the name " topo ". At this point, the contour line are 2D breakline with no elevation.
I then opened a new draw to which I did associate my draw " topo ". Then I used a querry to modify the elevation of the line using the attribute " contour " in my table, thus resulting in my breakline to become 3-D. It works fine. Then I save the new draw as " 3D_Topo ". I then get a warning :
" The association between objects interogated in the current drawing and associated will be deleted once the current document of the draw is closed " (I made the translation from french to english, in french it stated like this : " L'association entre des objets interrogés dans des dessins courants et associés sera supprimée une fois le fichier de dessin courant fermé. " ).
Well question #1 : What does this warning mean / imply ?
Then, I have those .ecw files as ortho photo which I want to import. So I use the fonction " connect " with raster image, then I select my file, then I " add to draw ".... then something very strange happens.
Sometime, the image appears correctly...and some other times I get nothing and I get this " disconnected " message in the task pane ..and no matter how many time I actually connect again the .ecw files, it will not happen in the draw ! Then I simply close the draw, start map 3D again, then I do the exact same thing, and sometime it works, sometime it doesn't... am confused here.. any clues?
Question #2 : any clue on why the .ecw files sometime works, sometime doesn't?
Now, let's assume I finaly made it to connect correctly and that Map3d didn't crash whilst I was doing it (because I don't know for you, but here, it does happens quit often), I now have (as shows in the picture I attached) two thing. A surface made (well, I went back in the civil 3-D module to make the actual surface from the breakline definition) with the contour line and a imported image. I now want to drap the image on my surface! So I use the option " drap " which is in the surfaces option (in the ribbon surface tools)... well it looks nice since it propose me to use the surface I made up with the controu line as the base and the imported .ecw files as the file to be draped upon. So I simply do that and.... well...nothing happens! My image isn't draped at all, it stays there, and am confused, where did I go wrong?
Question #3 : How should I proceed to actually drap my image over my surface ?
Question #4 : Considering I made it to drap the surface, how can I save this new draw independatly of the attached other draw or databse?
Thanks alot for the help!!

It means that, after the query, you should detach the TOPO drawing.

No clues, I'm sorry.

I guess you should click on the 3D button near the "Vertical Exaggeration" control.

After detaching the TOPO drawing, save all "as" another name.
Hi, thanks for the reply!
When you say detach the draw (in question #1) you mean from the task pane ? (just making sure)..
On question #3, you say that I should click on the 3D button near the "Vertical Exaggeration" control.
I am not quite sure about where this 3D button might be. Are you talking about the surface property (implying that this is a simple problem with the display and that my draping did work?).
Because I don't think it's a simple mather of display here.. I think the raster image I imported really don't drap itself on my surface!
If this is not what you are telling me, I am sorry I do not understand exactly what you are pointing me (it might be pretty obvious but I am not that good with Civil 3D so.. sorry for being slow ! )
I also have another question, which arose lately. I realised that, after I create my surface from the 3D contour line (or break line) these line still are displayed in background. I tryed to " delete " them but as I expected the surface disapears as well (I guess since it's definition are gone..it's logical). But is there a way to get rid of those line once my surface is made? I mean, they are no longer usefull and they drag power for nothing.
Thanks alot for your support !
You attach/detach the TOPO drawing by means of the same _ADEDRAWINGS command.
Even if this is not a Civil forum, you could get rid of unwanted contours as follows:
1] export your C3D surface with _LANDXMLOUT
2] open a blank drawing
3] _LANDXMLIN
Oh, nice trick! Worked fine ! Thanks 🙂
I will ask the question about draping in the civil 3d section! Thanks for you help, very appreciated!
