I think Joe is getting to the heart of our questions. What you need to do may be possible depending on what is in the drawing. So far all we know is that the drawing is 2D and that Civil 3D commands don't work. That's not enough information to offer a specific method of getting it in a form C3D can work with. It's like asking a mechanic to tell you how to fix your car without letting them look at it.
What we need to know is what IS in the drawing. As Joe mentioned; some key items are Points and what they are composed of, Contours and what type of polyline they are and if they are at elevation or just labeled. Also are there any existing Alignments and Profiles and what they are composed of.
The ideal would be if you can post the drawing or a portion of it. If that isn't possible. A listing of each item would help. Once we know what we're dealing with we can post some more substantial suggestions.
Thanks guys for your replies. I really appriciate all of them! I am so happy that I found a way to discuss and share our experiences. By the way, Allen, I liked very much your comparison with the car.
For the moment I have a small project in process. I am waiting for the final plan from the surveyor. Maybe this time the surveyor will give me that as I want, to open directly in the program.
But this has always been a problem for me and I thought to discuss with you in advance. But now I see, that you need the file (Car as Allen said) to have a Deep Look on It, and you are right.
Thanks a lot!
I will attach it as soon as possible!

Thank you for letting us know the status of this. When you want to continue just add to this post. Most of us have it set so we are notified by email when a post is added to a thread we're participating in.
You have what appears to be good information in this file. There are AutoCAD points at elevation and polylines at elevation. You can make a surface from both of those elements and start your design from there.
Yes. As Peter said; it looks like you have a usable drawing there. Whatever software the topographer used, could be Civil or Land Desktop (or other), everything is exploded into simple AutoCAD entities. There is no existing Civil 3D Surface. You'll have to create it from the points and 3D polylines.
It looks like there are a couple of blown shots in the drawing. Tip it up in to 3D and you'll see the areas I noticed. Either don't use that date or ask the person who produced it for a corrected file.
It appears that you have a mix of 3d polylines, ACad points and survey point data in this drawing. When I orbit the viewpoint I notice right away that some of the 3d polyline elevations don't make sense and that that survey point blocks have all been exploded. Most of the polyline vertices do not have survey points attached so I don't know how they were created. Contours have been supplied but it's not clear to me what data was used to create them.
You could use the contours and the points to recreate the surface, but that is not really the ideal solution. I would recommend that you go back to the surveyor and insist that he provide some answers to:
PS: A picture is worth a thousand words.
Hi Allen! Thank you so much for your reply. Unfortunately, I am still confused about It. In fact that was my question how to create surface when everything is exploded into simple entities.
What I have learned are two ways:
To copy this entities by using ctrl +C and paste to original coordinate, but it doesn't work.
The other way is:
Import points from the source file format csv. In this way I call points and I can make everything with that, edit the points.
And after that I know to create the surface.
I see that the points in the drawing have three datas x, y,z, and polylines, contours also, but how can I use them All to create the surface.
Please, I really need your help. Maybe, you can sent me a link (the video) to illustrate It.
I have found many links in youtube, but none of them as an example like that.
First create a new surface blank surface to contain the data. On the Prospector Tab of the Toolspace, expand the Surface and the Definition until you see Drawing Objects. Right click on Drawing Objects and select Add. In the Add Points From Drawing Objects dialog box, you can select the type of entity you want to add. Below you will see it with the option to add points.
You can also add other types of drawing entities.
Right click on Breaklines to add the 3D Polylines as breaklines.
Hope this helps.
BTW As I and others have mentioned. There are some problems with the drawing that will have to be addressed before you can create a usable Surface.
