ArchiCAD’s Edit menu includes a tool to Replace Text anywhere in the project. There are a few options worth mentioning in this tool. The first thing to mention is the filter options which is accessible in the first palette that comes up when opening the tool.The filter options allow you to limit or extend the search by stories, layers visible, by element. You can exclude or include text elements, labels, dimension text, opening text, zones and object texts.
Once you select your filter options and search for a specific text you will get a list of all elements included in the filter that was applied to the search. The list will show elements that you have reserved and that are on visible layers as black text. All hidden or unreserved texts will show as gray text. To go to a text element from this menu, select the text from the list and click the magnifying glass at the bottom.
