Hello members of the TC, if a 3D shape is read from OOXML by an import filter, it is currently not possible to store all of its properties to ODF. Some questions: (A) Is it possible to extend ODF so that the OOXML information can be used directly? Would it make sense to extend the standard in this respect? (B) A custom shape (10.6.1) has the attributes draw:engine (19.146) and draw:data (19.131). Would it fit to the desired purpose of these attributes, to use them to store such OOXML information? (C) Do you have a suggestion, how to preserve the OOXML properties in ODF? Kind regards, Regina
