I have routed a PCB in proteus ares and now I want to increase the track width. At the moment I am just drawing lines in order to increase the width. But when I obtain the output PDF it can be seen that there are places where the copper is missing (attachments). So how to increase the track widths properly ?
You can easily increase or decrease the track width, Just go to track mode(Right hand side below package mode) and select the thickness you want. If you are not satisfied with the thickness you can make one of your own thickness.
