Elevations over Corridor C3D

[Isaac26a]

Hello everyone, I have a big question about how to handle this.

I was sent an ACAD only file with elevations made with C3D and this is a sample of how they are asking me to do it, the texts in cyan are from the EOP and the elevation of the sidewalk, I usually handle this by creating a corridor and then making the surface and then I can use a spot elevation point anywhere I decide, but as I saw this this was made by choosing the elevations @ every 2 m over the alignment.

 

Does anyone know how should I handle this?, please give me some advice. Thanks in advance for the help.

Your stuck and you have even more issues, if you convert the text to a XYZ point to make a surface that is sort of ok, have a good look at the text on the edge of the road the text it is not lining up with the line work. You need to look at insertion point of text, and possibly move all of them so insertion point aligns  correctly as a first go.

 

Without some control I would send back your just asking for trouble in a street road job, this is what I have been doing for the last 17 years. Stuff up the levels guess who they will look at to blame.

 

Ask for 3dfaces would be better of design surface.

Hi Al, I know the person who did this didn't took the time to fix the levels in the cul de sac, but beyond this error, which I should take care of, how can I get Civil 3D to give me the elevations over any alignment like the ones shown above?. Now the other solution of using 3dfaces also seems a good idea, what do you think about using break lines to do that, do you think it would be possible to put elevation points over the breaklines and get the elevations lets say @ 1 meter or @ 5 meters?

 

And your idea of converting the text to XYZ points sounds interesting, how can I do it, do you think that can be solved with a lisp?, give me a hint about it, maybe I can use it for something else or for some projects someone just send me the texts like this time, to recreate the surface.

 

Thanks for taking time to help me solve this issue.

Try this, isolate the text layer before running. Can us add Autocad drawing objects to surface.

Thanks Al, an excelent solution for converting the text to XYZ points, as always you're quick with the answers. This will help me a lot.

Look at where the points are ending up as it uses insertion point sometimes need to move all the points 1st so point ends up where it should like on a line.
