Creating Points to contours

[Anonymous]

I ecountered a problem while creating contours from the points.
Please if any one can tell what actually is the problem with the points or tell the steps once again that would be great.
I'm attaching the points file

1. What steps were you following?
2. At which step did you encounter a problem?
3. What was the problem?

See first I imported the points.
Later I created Tin surface and pressed on contours and nothing comes up. If got a better solution please tell me ASAP.

You should operate upside down:

1. first, you create the surface definition
2. then, you add the points to it

Here's what I get when I import these points, Not sure what exactly your doing with the points but YES there are problems with these points. I would go back to the source if possible as it would be easier than guessing what to do about the points created using only 2 values when your looking for X, Y, & Z.

And by the way, I was able to create contours by creating a surface of the top image, it ignored the bottom image points because they contain X Y values only.

Two similar point shapes at different coordinate ranges because a portion of ascii file is only 2 values.

Starts with:

1993.5665 765.989 110.85
1993.5708 775.9846 110.9
1993.5665 755.989 110.25
1993.5544 706.0011 106.67
1993.569 745.9865 110.63

Then:

2104.4424 471.8966 SHED
2101.5823 473.9491 GENERATOR
2016.0115 617.0824 BUILDING
1726.1911 474.1796 SHED

(The above descriptions causing parse errors)

Then:

622.416 683.809 
618.597 668.407 
608.134 673.865 
597.296 675.221 
610.635 685.127 
642.872 674.109 
656.456 656.068 
646.063 656.687 
629.768 663.442 
633.394 676.302

Well, if you import those points in a ENZD fashion, you won't discard any of them, sir...

[Jay_B]

For whatever reason, I don't have that option in my list for "Import Points" (with filtering OFF).

Figured it out, New user.

Please could send me that file which you created or tell me the steps in creating those. Thank You

I did it in NEZ format . As you told to do the opposite way i didn't get any contours either.

[Jay_B]

The problem with the ascii file is the manner in which the data is organized within the file, as anotniovici suggests if there were in fact 4 parameters on any single line within the file you should get the 4 parameters if you choose "ENZD fashion".

However there are no lines in the attached ascii that contain four point parameters, there are as few as 2 per line and up to 3 per line.

The file contains random data for N,E,Z & Raw Desc.

The file is being read line by line during import and that's why there are 2 similar images and many out of range elevation issues.

The Raw Descriptions will not show up because it's treating the 3d parameter in any case as a Z value and being discarded with parsing errors.

I attached the file I was able to create contours for and the steps were:

Insert Tab>Points from file>format NEZ or NEZD>Rt click on "surface" in prospector>create surface>expand surface name>expand definition>rt click on point groups>add.

Now should have not so pretty contours with several trouble areas and roughly 700 ignored points.

Hope this helps.

Check the attachment out (ENZ format).

I 've done the editing . I'm attaching the point file in NEZ format.

Please check whether this is producing contours or not.

[Jay_B]

Looks much better now see attached

I'm using Civil 3D 2011. Please could you export it in that version. I'm attaching a DXF file . which i created.
Please see whether it is correct.:)
