Using AutoCAD 2002, I work for my local municipality, and we have a master drawing for our services, indicating hydrant, manhole, watervalve, and main line locations. We've basically created each object (ie manhole, valve, and hydrant) as a block with attributes, including the type, location and direction of flow. Currently, they have a null value for data, as we're in the process of setting up a system to assign numbers and such.
Now, here's the problem: I can't change the block's layer, no matter how hard I try. For example, if I create a hydrant block, and put it on the layer "hydrant", I can't transfer it to our main water line layer called "water main". I've tried exploding the block, changing the layers for the hydrant block, and then blocking it again on the "water main" layer, and then matching properties for the rest of them, but something "remains" on the "hydrant" layer. I've checked the block attributes under modify>object, and my three attributes show as being under the "water main" layer. If I freeze the "water main" layer, the hydrants disappear (even if the "hydrant" layer is on). This is expected. However, if I turn off the "hydrant" layer, and leave the "water main" layer on, the hydrants still disappear.
In a nutshell, for reasons I wont get into, I had to put the hydrants on one layer as a block, the valves on another as a block, and the main lines on a third layer (no block). Now, what I want to do is put all three sets of objects on the same layer, and delete the other two layers.
Sorry is sounds so complicated, but it's an annoying problem...
Thanks in advance...
