hello?     There are some groups in my AutoCAD DWG data. Groups in Autocad means a whole that when you select a group in AutoCAD ,you'll select all element in it. But when I read these groups data in FME, they'll be auto exploded even I set the 'read group' parameter to 'yes' in Reader. And I could not find some relationship between those features which are one group. How can I resolve this problem in FME. 
Hi,

 

 

Did you try referring to some DWG format attributes e.g. autocad_group_name?

I've tried your suggestion.  Whether or not to set 'read groups' to 'yes' in Reader parameter, then I used a AttributeExposer to expose 'autocad_group_name',  output the data to Data Inspector,  but I couldn't see any attribute named 'autocad_group_name'. It seems this method dose not work.
Hi,

 

 

Does the setting RESOLVE_BLOCKS have any influence on the result?

 

 

I know blocks are not the same as groups, but if the group is read as a block it might get exploded if the reader is set to "explode" blocks?!

FME reads the groups as separate features, which have no geometry, but do have a list (autocad_entity{}) of the entities that are part of the group.

 

 

I have created an FMEpedia page showing how to use the Group features to recreate the AutoCAD aggregation:
