Hey There!
We recently upgraded to Acad 14 and experiencing some issues with the "MatchProp" command. No matter the layer or type of object destination, unselected nearby objects are being effected when the command is used. This is occuring in new and old drawings.
For example, in the attached photo, pictured left is two polyline squares and two hatches; all on different layers. When the center solid hatch pattern is selected, with a destination to match the pinstrip hatch, the outcome is the group to the right. Even though the hatch patterns were the only items selected all lines and hatches now share the same attributes.
What gives?
