VW2023 Survey Import File Types

[Stu Wilson]

Hi All,

 

Does anyone know the best file type to import a survey that produces the best 3d model of a site survey?

 

Thanks in advance.

Point file in .txt or .csv 

basically, it’s a list of points collected by the surveyor, it’s the rawest data.

At a minimum, it consists of point #, X, Y, Z.

Or point file as .dwg that imports as 3D Loci...? Or @jeff prince are you saying you prefer .txt/.csv as then a layer of processing on surveyor's part has been cut out + therefore some potential room for error eliminated? I have used both formats but .txt resulted in a ton of processing on my part but perhaps under other circumstances I could have insisted the surveyor present the data in the format of my choice...

using the sources data as points from a delimitated file is the most accurate and fastest way to generate a site model in my experience.  Processing contours takes forever in comparison.

I'm talking about 3D Loci not contours. I just import the .dwg + there are a load of 3D Loci in the right x/y/z locations then select all + make site model.

Building a site from a text based delaminated point file is still faster.  Try it sometime compared to importing a .dwg with points in it and you'll see.

The added benefit to a delaminated file is you can open it in a spreadsheet or text editor to check the data for problems, edit, or reformat it.

 

Stu asked for the "best file type", that's what I provided.

we have the .dwg but its not x/y/z formatted, its just a number over A.O.D. i have attached  the survey for reference.2303013-Anyards Road-Post Demolition-REVA.dwg

Can you go back to the surveyor + ask for the geometry in 3D? And/or the survey points in .txt/.csv format? They have given you a 2D only file. They should have the 3D data but probably assumed you were working in 2D only.

 

As a last resort there is a script here on Forum somewhere which will convert text objects to 3D loci.

There's another thread somewhere with more detailed info on this option, but I can't find it.
