import dng to dwg, cannot see all data in autoCAD.

[faveo]

Hi

 

I am using autocad civil 3d 2010. I got .dng files (in 3d) from a customer. I was able to import the data to .dwg (no problem). However, some data seemed to be missing. The customer could see all data in microstation. He said I needed to change the display depth cause some z-number were -99999. That is probably why I cant see all data in autocad. My question now is how do I change the display depth in autocad? Has anyone else had the same problem where you cant see all data when you convert from dng to dwg? Did i do something wrong when I imported the files?

 

Thank you and Im looking forward to read your comments.

There is no display depth in AutoCAD. And why would any of the geometry have a negative Z of 99999 in the first place?

Thank you for your reply! I know there is nothing called display depth in autocad but I thought maybe there is something equivalent to microstations display depth.

I have no idea why the geometry would have negative Z. This is just the information I was given. Probably some of the data were not planned to be used in 3d drawings.....

Any solutions to my problem. I am really stuck...Why is some data displayed properly while some is not even shown?

Are you sure all layers are turned on or thawed?

Yes. Just looking at it now.

The use of -9999 is to say this object is non contourable. DGN to Acad yeah nightmares. Check into translation tables to really get 100% results this way it takes microstation objects and makes new acad objects using properties not a object convert. Any one who has imported DGN's will know about the A B C D e's etc

Thank you for your reply. I have never used translation tables. I am not in any way an advanced CAD user. Can you give me some guidance? I would really appreaciate it!

Its been years since I had anything to do with DGN some else will need to help. Only know what the last dwg looked like from someone here in the office.
