Data Extraction from grouped objects

Anonymous — Wed, 18 Sep 2019 11:28:38 GMT

Trying to extract data from a set of "group objects" ... is there any way of doing that? The idea is to understand on a spreadsheet what and how many objects is contained on every group. Thank you!

data extraction needs blocks, not groups: look p the topic in HELP, there are some good tutorials there that explain the process.

Thanks Pendean but... Not an option.

The thing is: the GROUPS do exist (About 600!) And i want to be able to list the content of each group... (to an Excel file would be very apreciated)

I can add the information: Each group contains only blocks.

Earlier i mentioned the "Data Extraction" for reference but what i really need is to understand if is there is such tool that can extract this "Metadata"

Group A: 5 x block-a , 2 x block-c;

Group B: 1 x block-f, 34 x block-g; ... etc...

Thank you!

If I understood your need correctly, that's not an existing automated task in the program: your blocks will need to contain the 'what group am I in" information for it to be exported, GROUP objects are not tracked in DATAEXTRACTION (and there is no other tool that does that).

Maybe that's something someone can help you develop in LISP instead: that dedicated forum is over here https://forums.autodesk.com/t5/visual-lisp-autolisp-and-general/bd-p/130

Hi,

agree with @pendean ... groups are not supported inside command _DATAEXTRACTION.

I just want to add: take care if you want to count objects as one entity can belong to multiple groups, it would be counted then as more than one part!

What you're asking for would be possible by using a customization such as LISP. You could do a search to see if one exists or start programming. The caveat that @Alfred.NESWADBA mentioned would also be true since objects can be members of more than one group and some objects wouldn't be counted unless they were in a group.

@pendean ... Just wondering about your sugestion... how about a tool that can convert GROUP to BLOCK? ... This way DATAEXTRACTION would be possible! 😉 ... (All elements belong to a single group that should be "easy")...

If you know such tool, lisp, macro,... what ever... it would be very nice, not only for me i'm sure!

thank you! 🙂
