Why are question marks appearing in wire number tags in my project?
The software appends question marks to wire numbers to avoid creating duplicate wire numbers. This situation is often encountered after copying pages from one project to another.
Consider clearing the Maintain Wire Numbers check box or setting it to "Tag Only" on the Copy Page(s) dialog. However, using "Tag Only" may not help. When "Tag Only" is used, the Wire Tag value is preserved but the Installation and Location of the page resulting from the copy are adopted by the wires. If there are already wire tags with the same installation and location values, question marks will be appended to the tags on the new page.
Use the Wiring Manager to change the Installation, Location, and/or Wire Tag values of wires with question marks in them.
Use Automatic Wire Number to overwrite the wire numbers of a selection of wires, a selection of pages, or the entire project.
