We have received some drawings that are converted ArchiCAD that have 1000's of blocks, things like one section of straight wall is in Block named "Wall-132" or something - everything is a block.
We want to use the lines in these drawings because they apparently are accurate and comply with all regulations - no reason to change them.
But we need some control over all the layers, and the layers in the blocks are a problem. All we need to do is convert all the layers inside the blocks to layer 0.
Is there a way to do this easily? Some command that will allow me to do a mass selection of all the blocks then change the layers inside the blocks to 0? What would be the best way to do this?
