Hello,eight months ago, I have opened, via my VAR, the SPR 1163982 - 'EXTRACTBLOCKATTRIBUTE command does not extract data when attribute name in template contains dot symbol <.>.

Dassault tell me that the issue will be solved in Draftsight 2020 sp2. I have installed this version but...... the issue is not solved. Anyone could help me?
