Outta My Way! (Interference)

Some would call this a workaround. Well, it is.

AutoCAD Architecture wall objects allow Interference Conditions.  I use this feature to show my wall boundary being cut by recessed fire extinguisher cabinets.  The block I use for the cabinets includes a mass element, which is what cuts the wall.  A problem arises when attempting to use more than one fire extinguisher on a single wall.  Apparently there is a rule with Interference Conditions that a single item cannot be attached to a wall more than once.  Even though each instance of the block has a unique handle, the mass elements within each block all are technically the same object.

This leaves two options:

1.) Break the wall into two separate walls.

2.) Create a duplicate block definition, and make sure to copy the mass element so its handle is different from the original.

Either choice should work fine, but I chose to create a new block because I didn’t want to break the wall.  Plus, I now have an extra block ready to use next time I encounter the same problem.
