Importing survey into mesh

Anonymous — Thu, 25 May 2023 15:06:24 GMT

my surveys come in as .dwg Most come without .shx files. The book mentions xyz, could I interpret pts to xyz and get the result in AC14? or what do I tell the surveyor as to the form of the file I need to implement this feature in AC14

As it says in the Reference guide
"Import any text file containing xyz data (e.g. surveyor’s data), or similar data, into ArchiCAD,
creating a Mesh element automatically."

I read that about text file, my question is: can I, change the dwg file received into a "txt" file?

No not directly. Ask your surveyor to provide point file for the survey. Typically this will come as a .txt file listing the xyz coordinates of the measured point of the survey.

Another option could be to download DWG/DXF to XYZ file converters. I haven't tried any yet so I can't vouch for it. But I have seen quite a few search results that make it seem valid and possible.

This is the main reason I made the upgrade from v10 to v14.
Although my six month old Macbook pro had a heart attack the day I received my software.
Can't wait to load it onto my new hard disk and start making it pay.

Xyz file works fine for me. Only problem is that the file should be prepared properly outside ArchiCAD. AC could not interpret it in another way (eg. zyx, skip first line etc).
Importing data is very fast and the mesh is shown ready to place (in ArchiTerra you import points and then prepare borders and then generate mesh)

I'm about to import a file from a surveryor and I was wondering if the contours are present in the file (xyz or txt). Basically does Archicad translate that information and make a nice contour lines when it imports or is that something I need to add myself? The reason for the question is that I want to be able to see those contours in 2d so I can easily laser cut it. Though it sometimes doesn't matter what the contours are set at it really has to do with the scale and thickness of the material for that you are going to laser cut.

I just am curious if the contours are represented in 2d and/or if there is a method for representing that data in 2d some how?

Thanks.

There is a method described in this thread, but the contours are straight line segments at each mesh plane, not curving contour lines:

Thanks for the tips, guys.

I used a vertical stack of slabs to generate the contour lines, with SEO to automatically update them as the mesh changes. This generates all 16 contour lines in one step. It allows me to concentrate on the high points, valleys, and various spot elevations that I want to see on the site, and let the contours draw themselves.

So here it is, almost 1 year after this old thread....

Just ran across it and thought why not combine the two techniques into one... I created a VERY simple object that puts alternating slabs (tried it with planes but didn't produce the results)... for you to place as an object and INTERSECT with your mesh..

I found if you use the FREE MESH, it will add the GRID lines of the mesh; which are not contours. But the regular mesh works great...

I suppose, if you want SOLID contour lines, you can simply PLACE your 3d Document on top of your mesh in a layout to see them. This way it will constantly update...

Try it out if you're still interested.

Hi Duane
Thanks for posting this object.
Not had to work with meshes but the tiniest amount so far so please forgive
if I'm not getting something basic here.
First image is of basic test mesh I created, with your object placed on top and peaks of mesh showing above.
Second image (next post) is what I get seen in 3d after doing "intersection" seo with mesh as target and your object as operator, and your object then put on hidden layer.
Somehow it does not seem right, so think I missed something here.
Third image is what I see in 2d.
Am I missing something simple, or just messed the whole thing up?
Would appreciate comment when you get time.

Second image
After seo and operator on hidden layer.

EDITED: Well now I know why it looks funny.
It's before I changed default setting of mesh to all same materials.
See 4th post above.

Now with mesh set to wire frame, things are looking better for 1st try in 3D.
But can't get 2d(next post) to look like this 3d which seems like I might be getting there if I could only get 2d to look like this 3d based on this simplistic test mesh which does have straight lines, and no soft contours.

And now 2d with same settings as previous post, just below.
But obviously somethings still not right.

Here is "second" image with all edges same, before wireframe in 3d.

Its the 2d that is being such a booger.

Here is a separate but related question; My civil engineer represents engineers well and can't get me the xyz, or text file, but he will, though in the mean time after several calls and emails he has finally sent me the wrong set of files that are in DTM formate. Does anyone know if there is a way to translate that out into a xyz or text file without the platform of genesis.

So the surveyor sent me the points file as an .auf

Never heard of this file ending. Can I just change it to a .txt file or am I still up the river?

[size=24][/size]wow!

[size=15][/size]I just changed the auf to a .txt and all I can say is wow, it works!

ok, now you see it! How do I chop off about 200 feet from the bottom?

I tried importing a surveyor's data file in .txt format with the new mesh improvements in AC14. AC did not state any errors with the file, allowed me to choose options from the units dialog box, previewed the overall shape of the site, and allowed me to click on the plan at a location of my choice.

The only thing is - nothing happened after I clicked. No delay, no message, just nothing. And there is nothing there. I tried again with the option of placing it at original location and the same thing occurred.

The .txt file is in rows of data like below:

2,21458.9837,18749.24411,491.96,TRAV PIN
3,21518.36934,18487.53931,496.65,TRAV PIN
4,21682.79711,18483.56612,502.68,TRAV PIN
69,19842.01943,18999.61536,-9999,TRAV PIN
70,19950.32139,18999.80376,-9999,TRAV PIN
71,20085.77784,18834.31791,-9999,TRAV PIN

Appears to be ok with point #, northing, easting, and elevation (x,y,z). The only things I question is the frequent elevation with -9999 like the one shown and the lack of points between 4 and 69. Could those contribute to my mesh not producing? If the .txt file appears to be in error, wouldn't AC have not only informed me but also been unable to preview the outline?

Thanks - just wanted to see if I could have something to start discussion with before I respond to the surveyor for further inquiry.
