Hello All I have about a hundred different hydraulic blocks in a drawing accessible via design center. I use the layer 0 to define line colors when inserting into other drawings which works well. What I would like to know is, is it possible to have multiple layers on a block that can be assigned to a layer on insertion into a drawing. For example a DCV will have a pressure line, a tank line and two working lines all of which are different colors. Would it be possible to set the block up so that on insertion it asks for the layers for each of these lines separately? Sometimes the pressure line will be red for high pressure and sometime it will be blue for standard system pressure.
Also is it possible to have text in a block that stays horizontal if the block is rotated.
Lastly, is it possible to search for a block that is inserted in a drawing? For example recently I wanted to purge a block from a drawing but Autocad would not let me until I had found and removed all instances of the block in the drawing. This can be a time consuming process if the drawing is very large or contains a lot of similar blocks.
