Hi Zeeshan and welcome to the community forum!
You can do one of two things to fit the design into a border:
A. To choose a different border with a bigger size you need to go to the main menu; Graphics, then Border, and then you'll be able to choose from the existing ones you have defined in VeSys Symbol
Seeing as the border you have is already an A0, so you will probably need to create a bigger one (note that you can choose a custom size and define your own size of the border needed)
B. Otherwise, if you want the border size to remain the same, then you can decrease the pin grid spacing used on the diagram by going into File > Project Preferences > VeSys 2.0 Design > Diagram, and changing the Grid Spacing to have a lower value. Once that is done, if you create a new diagram the settings will be applied to it, and if you copy and paste all you have from the first to the second diagram then your devices will be smaller compared to the old ones (they will occupy less space inside your border). Note that new settings will only apply to new diagrams, not existing ones.
Hi Muhammad !
Thanx for the reply. I've tried "B" and it worked.
