working with a 2d survey drawing?

Hi

I'm exploring the option of going from normal autocad and PDS (for our road designs) to fully using Civil 3D 2013

 

Generally we only recieve a survey drawing as a 2d cad file with height points represented as 2d text.

In PDS all we need do is 'convert text to point' and create a ground model, this gives us a 3d ground mesh to work with.

 

In Civil 3d i've found 'movetexttoelevation' but now i'm stuck with adding a point at the node of the text object, and then I need to creat a surface model to overlay a 2d siteplan andstart creating our roads.

 

Any pointers in the right direction is much appreciated.

Many Thanks

Basically you can push text to the elevation it represents then add the text to a surface directly.

This method will work with the caveat that the level point will be at the insertion point of the text which may or may not be at the actual level point. This will make the resultant DTM inaccurate although in some circumstances this will be acceptable eg. large open site with little detail whilst in other circumstances e.g. congested site with much detail it may not be.

 

If the text is all consistently offset then it is possible to ofset the text back to the correct location with not toom much hassle but if the text is rotated and at varying offsets then there is more work to do.

 

I use a the following routine which works well (although may need to be run a few times where ambiguous points are found) http://howtoautocad.com/autocad-civil-3d-survey-fix-tool/

You can use a lisp program to convert the text to acad points or you can use DATAEXTRACTION (my preference)to create a csv file of point.

 

Note: due to upload restrictions, for some reason dxe files are not permitted? Rename the txt file to have a .dxe extension soy you can study it.

Thank you

.....always remembering the caveat about text insertion point vs actual level point.

C3D can use the text/mtext objects to build the surface without points. After you move the text or mtext to elevation, go to the surface definition. Expand the defintion tree and right click on Drawing Objects. In the drop down list choose Text and select the text/mtext objects.

This tool will convert level point to elevation of text.

Can be used in autocad as well.
