Open a Solo Project

Use File > Open > Open... to open a solo project.
The Open file directory dialog box appears. Browse for the project you need.
Launch a new instance of ARCHICAD: Check this box if you have another ARCHICAD project running already, and you want to open this one in a second instance of ARCHICAD instead of closing the running project.
Open and Repair selected file: If the selected project cannot be opened the first time, check this box and try again.
