Need to extract X, Y, Z of Point Clouds in schedules - But how?

[alexliz]

I am using the IES-05 Object Inventory schedule as a starting point. I am reporting on Objects only, which are located in the Point Cloud layer in my project.

Fields reported in my schedule are Library Part Name (so I see which Point Cloud it is), together with the three 'Survey Coordinate' fields. I thought I was getting the real coordinates of where the point clouds in my project are, but it turns out that I am not.

Anyone could please advise what the 3 fields are returning?

The project Survey point is set at Easting/Northing/Elevation all set to 0.0000.

EDIT: I am now thinking that this has to do with the fact that I have set the project location, using the Latitude and Longitude fields - am I right? At any rate, what is the way to get a table with the values for X/Y/Z values for a number of objects in my project (or other elements as well)?

Thanks.

"cloudcompare" can do this but its "a little nerdy" - but you can donate to them as You wish. there are tutorials.

Hi @alexliz 

As far as I know, Survey Coordinate X, Y and Z show the element (insertion point) coordinates related to the Survey point location. Latitude and longitude at Location settings dialog are meant more for energy analysis, sun position and shadows, while native survey point is for collaboration with others (watch this video).

Kind regards.

Thanks Ricardo. Problem is, the numbers returned in my schedule aren't the same as the coordinates when I check with the cursor (and project zero is at the default location, not moved etc).

[alexliz]

Thanks for the reply but I'm not sure this has to do with what I'm asking.

i need to read more carefully - not onl,y the headline. Sorry.

Pointclouds in Archicad are insereted as library-parts.

Each library-part has his own location-coordinates, when inserted into Archicad. So said - the coordinats of the zeropoint of the library-part where it is inserted into the Archicad-"room".

The manually shifted coordinats of the project itself:

In the german version of the GDL-Handbook 26  on page 346 you can read this parameters as "request" commands for using it in GDL (language of the library-parts and also for schedules?)

GLOB_PROJECT_LONGITUDE project longitude (project dependent, do not use in parameter script)
GLOB_PROJECT_LATITUDE project latitude (project dependent, do not use in parameter script)
GLOB_PROJECT_ALTITUDE project altitude (project dependent, do not use in parameter script)

Within an library-part GDL - it can be read out with this on page 353:

SYMB_POS_X position of the library part (x)
relative to the project origin (excluding door, window and wall end: relative to the startpoint of the including wall)
SYMB_POS_Y position of the library part (y)
relative to the project origin (excluding door, window and wall end: relative to the startpoint of the including wall) Note: see the section called “Doors and Windows” for orientation of Y and Z axes
SYMB_POS_Z position of the library part (z)
relative to the project origin (excluding door, window and wall end: relative to the startpoint of the including wall) Note: see the section called “Doors and Windows” for orientation of Y and Z axes

When activated in Archicad, You can open the librarypart-GDL for the pointcloud itself and read in the masterscript, the 2D and the 3D-script  and use the request-commands above to get the numbers and you could write it with gdl-commands in the 2D-script, to display it in the workspace for controlling-reasons - but it would go too far in this text here to show how.

I guess my question could really be rephrased to this:

Is there a way to list in a schedule in Archicad the *coordinates of any element*, i.e. the X, Y (and Z, if applicable) in relation to Project Zero?

For example: if I create a 2D line that starts at 0,0 and ends at 10,0 is there a way to 'grab' it's start and end points' X and Y values and list them so I can export to a the simplest of spreadsheets?

I am surprised at how difficult this simple proposition is proving to be.

Hi @alexliz 

May be it is not what you have in mind, but there could be a workaround using the Coordinate Dimension object. You could place it wherever you need and create a schedule. You could select the desired origin and even create your customized one; if so then you will have to search the Custom Coordinates in the Library Part Parameters.

I hope it works for you.

Best regards.

[alexliz]

Thanks Ricardo.

Wouldn't this require inserting the object once for each element I need to report on?

[Ricardo Lopez]

Good morning @alexliz
You can place the point where you need it and generate the list from those points you consider appropriate. It is not an automatic procedure unfortunately.

Regards.
