Tips: 1. Don’t use Mirror command if layout has shear wall. Means shear wall to be created after mirroring layout. 2. Copy floor plans successively if shear wall present in layout. Means 1st to 2nd 2nd to !rd !rd to "th etc. !. Don’t store bld file in a folder name li#e $My document% or $&ew 'older% which contains blan# space between words. ".
