Hi, some mor.n spreaded tons of blocks through the drawing all containing attributes. Now the value need to be changed. The attribute has a preset value, in the drawing there it contains another one. Preset value 100x100x10 Drawing value 150x100x10 Needs to be in the drawing 100x100x10 Battman does not work. Attsync only mirrors the attribs. How can i get these attribs updated correctly? Jan
