Topography error

nikol_geo — Tue, 06 Oct 2020 13:05:30 GMT

i want to make a topography in revit using SPECIFY POINTS FILE command.

the .cvc file has 3 columns with numbers( 1. X coordinates, 2.Y coordinates, 3. elevation value)

when i try to import the file the below error message appear.

do anyone know how to fix this?

Can you provide the CSV file so we can look at what is wrong?

Try it as a comma delimited text file. Change CSV extension to TXT extension.

I've looked at the CSV file and import the data, apparently Revit won't recognized it from my end.

When I open up the CSV data, it shows up as one column instead of the three like the right. Also is there a reason why you have 6.016.227.813? Revit won't recognized this value. It has to be pure number value like the right.

you can use Civil 3D file from Civil engineer it's more reliable to create surface or use AutoCAD file that have elevations it can made easily from Surveyor man from site or by Civil engineer

@nikol_geo: What does this data represent? These are not X,Y,Z Coordinates. What are they? Care to share?

Re: Topography error

nikol_geo — Wed, 07 Oct 2020 17:19:39 GMT

they are coordinates that I had extracted from a topography dwg file

Re: Topography error

barthbradley — Wed, 07 Oct 2020 17:34:06 GMT

What kind of "coordinates" are they? Obviously this first entry is not an X;Y;Z: 6.016.329.023;40.953.472.142;36.60.

uuhm.... i don't know maybe i made sth wrong during the dataextraction in autocad?

I will look up to it again

Well, how did you solve it? You awarded a Solution Credit. What was the solution? How were X,Y,Z coordinates extrapolated from your CSV file? Neat trick.

I propably misclicked it. I have to see it again

Post your AutoCAD File. I'll get a Point File out of it. But, if the topography polylines exists in the dwg, why not just create a Toposurface from Import Instance?

Re: Topography error

Because i only have the points from the autocad file, that the topographer had send me.

Re: Topography error

See if this works. I notice the points distance are huge. So I basically set it closer to the centerpoint where Revit can understand. So use the TOPO REVIT-Split.csv

Re: Topography error

barthbradley — Wed, 07 Oct 2020 19:15:29 GMT

Unfortunately, there is no Z data to extract in this file.

Re: Topography error

nikol_geo — Wed, 07 Oct 2020 19:25:44 GMT

i think it's wrong... this warning keeps appearing

Re: Topography error

syman2000 — Wed, 07 Oct 2020 19:28:28 GMT

This is why I said to use the TOPO REVIT-split.csv instead of the other. The value is too large for Revit to process.

Re: Topography error

nikol_geo — Wed, 07 Oct 2020 19:45:21 GMT

It is off scale again.

I don't know why. It makes no sense. Because i have defined the units in meters both in autocad file and revit file.

I'm so grateful for your time @barthbradley , @syman2000
