PADS I/O Designer GUI (graphical user interface) startup preferences can be set under Setup > Settings + Gui Startup.
Three startup options are available:
Do not show startup dialog — PADS I/O Designer does not prompt you for the project to open. You select the file to open by selecting File > Open Project, or File > New Project.
Load last project — PADS I/O Designer starts and automatically reopens the most recently opened project.
Show startup dialog — PADS I/O Designer opens and shows a list of recent projects to select from, as well as options to start a new project or browse to an existing project.
Note
When PADS I/O Designer launches from within a PADS Designer project, PADS I/O Designer opens with that design project's design and associated PADS I/O Designer project databases.
