IF you don't take the time to learn them.
We have been getting floorplans lately that have the Room #, sqft, etc.. as a dynamic block, (I think). Within the block(s) are info on several layers. All we want to keep is the Room# & Room Name, then put those two bits of info on ONE layer.
When we 'mess' with any of this info, it resorts to 'Room Name' rather than 'X-Ray' - (It looses its info).
What is a good resource to learn about this? Is the help file worth watching?
