i'm using altium, and i have a board where i need to modify the pad drill-holes size. Is there a way for changing them all at the same time? I select one pad, and i find similar objects, and all the pads are selected. But when i press properties i can only change the properties of the first pad selected.
You should use 'pcb inspector' or you can use pcb filter too. If you will use the inspector you should set the 'include only' menus which is the top of the 'pcb inspector' menu. Select the pads then you can change anything about your pads.
If you wanna doing it with 'find with similar objects' you have to specify some of parameters. First of all if you wanna change the pads which X size 0.5mm Y size 0.5mm. right click any pads --> find similar-->holse size =>same, X size => same, Y size => same. Now you can edit pads.
