Proteus Ares line thickness

Hi all,

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 ?

In Ares... select the traces in the right window.... Right click on a pcb trace... Then select a bigger trace... Its easy.

Hey all I found it. Just use the zone mode (left side yellow "T" sign) and draw the shape you want.
