I have created a topography surface in the site view. I used a autocad file. The surface was created and I can see it in all the views except the 3D view. I have checked nothing is hidden. The imported file shows as a vertical line in the 3D view.

Hi Anjata, and welcome to the forum.
I´m not quite sure that I understand what you´ve already done... Have you created a Revit Topo from the AutoCAD file, or are you using the cad geometry as your Topo ? Could you elaborate a little, and perhaps include a screen shot or two ?Klaus Munkholm

You should see your 3D Cad import as contours or a TIN in the 3D view, if you are only seeing a vertical line, creating the topo would not be possible, as it doesnt sound like your 3D CAD survey imported properly
Topographys will be turned off by default in the 3D view as well, so double check the VG graphics again as wellComment

following to this topic. I have a slight problem with this topography. i received a site survey in CAD 2D and I would like to plot it now in Revit. I don't think I have the Z values table in there tho.
These are the steps I have taken to produce my topography, please correct me if I am wrong, or can be done quicker:
1. linked / insert cad
2. rescale
3. massing & site > topography > pick points (so here i type the elevation on every points and click it there)
...
am i correct?Comment

Correct. But how do you type in the elevation of each point, if you don't have the Z values??Originally posted by joss View PostKlaus Munkholm

oh. I have the point elevation...so those are z values
but they are not presented in a table like that in CAD. is there a way i can check if i got those table from the surveyor?
Thanks Munkholm.Comment

Looks like there is a 0 elevation (my guess) point in the dwg.Originally posted by anjata View Post
the vertical line might be a distorted view of lots of point in the top connecting to a lower (if not more) point below.
Try editing the surface in 3D end deleting the wrong one(s) in the same 3d or elevation view.
You can also check the problem in planview for very dense contour lines.
Hope this is the case...

little more problem
topo1.jpgtopo2.jpg3d3d_screenshot.jpg
im stuck! i would really appreaciate it if i can get some help here in creating and positioning my toposurface. On attachment there is my csv. file I extracted from autocad for the x,y, z points. I uploaded to Revit using toposurface >specify points files > and bam! it's created somewhere else so off the site.
My question is, how do I align it up with the original toposurface to the building?
On the 3D view, west side of the house, there is a big hole... I am sure the land doesn't look like that.
Am I doing this correctly?
Thank you. please helpComment

I am not 100% on this, but I would think the easiest thing to do would be to link your project into a new file with the site plan and position the linked model as needed. I don't believe it is the "correct" way to do it but it will work.Comment
