One of my drafters has tried to insert an attributed block from a standard company tool palette only to find the attributes do not appear in the drawing nor are they listed as properties of the block in the Properties palette. If, however, we go to the Block Attribute Manager and change the mode of any of the attributes (because they do exist in the drawing) the attributes suddenly appear in the drawing and on the list of block properties. The problem is limited to a couple of workstations. I cannot think of any possible variable that might cause this. I've even recreated the tool using the AEC Content Wizard to change the attribute mode in the reference drawing without success. I've attached one of the offending drawings so if anyone could take a look and let me know if they can come up with a solution I would appreciate it.
