This ARCHICAD Add-On can find, select, or delete items sharing the same parameters (type, color, thickness, height, etc...) and occupying the same spot on the floor plan. Unwanted doubles are typically created by either accidentally double-clicking at the same mouse position or by copying and pasting items several times to the same location. The new set of commands will appear in the "Edit > Check Duplicates" submenu by default.
How to use Check Duplicates Add-On
The Add-On will add two new commands to ARCHICAD: Select and Delete duplicates.
The Select... command will select and highlight all duplicated elements in the active window. If you placed a marquee in the window, or you have selected elements before evoking the command, then you can limit the range of the command to the marquee area or the selected elements. Only duplicates will be selected, the original item will not be affected.
With the Delete... command it is possible to delete duplicate elements over the entire project (all stories and sections). You can also limit the range of the command to the active window, or - if you have selected elements before evoking the command - to the current selection or to the marquee area. Clicking the Delete button will delete duplicates, but will leave the original element(s) intact.
The Select... command only works on the active story or section.
The Delete... command works on all stories if you select the Entire Project option.
