[solved] object data - IFC

Post by steverugi » Wed Dec 08, 2021 7:11 am

any chance to add object data in the future?
like in shapefiles for GIS or simple database purposes for SQL or just CSV
I use it in Autocad and it's super useful when you deal with objects and data information related to them
similar to block attributes but more granular and operating beyond the block itself

In QCAD, custom properties can be added to any entity using the property editor (View > Property Editor).
Click the plus at the bottom right to add a new property.

These properties could then be further processed, exported to CSV, etc. for example using dwg2csv. For example to list all block references with their position and custom property "myproperty":

Code: Select all

dwg2csv -t "Block Reference" -p Position:X -p Position:Y -p QCAD:myproperty custom_properties.dxf
Output:

Code: Select all

Position:X,Position:Y,QCAD:myproperty
33,27,myvalue
27.34,21.2,myvalue
...

thanks for the reply, much appreciated

sorry to bother, can properties of entities be exported in CSV, without using block attributes?
in Autocad I can do it by exporting it as SHP, it automatically creates a .dbf file that Excel can read
I don't know how to use line command, could't find much on the web so far, is it from QCAD command line or Terminal?
I am using the Pro version on Windows 10
thanks again for your help

Yes, dwg2csv does that.

QCAD does not export to SHP.

You can use dwg2csv from a terminal or command prompt of your operating system. If you are not familiar with terminals, this might not be for you.

If you are willing to invest time in this direction, here's a starting point:

Note that command line tools are typical power user tools, typically used in environments with high levels of automation or full automation (e.g. recurring processes, server environments, etc.)

I finally dedicated some little time to it and it works!
all objects can have custom properties in addition to their own and extracted via dwg2csv, it's actually easy
very useful stuff, thank you @andrew and QCAD
