TIAH cannot find the intersection symbol – what happened?
If TIAH 3 is installed on a computer where TIAH Beta was installed previously AND your default intersection volume symbol was set to a file that no longer exists in the C:\Program Files\TIAH\INTVOL directory, then TIAH will not be able to find it. The fix is simple: before proceeding to insert volumes for the first time, click on the “Block Styles” button on TIAH’s main toolbox and set the new default symbol name and path (see screenshots below).
