You asked for: PCB Editor / Edit / Edit Track & Via Properties / Filter tracks by width: …. If you want to use that, you should first add some widths to the Pre-Defined Sizes list in the Board Setup.
But I would start by learning how net classes work, and then use the settings from the net class. There is also no need to only select the 250um tracks. You can select whole nets and set all segments to the netclass width for example. There are different ways to do things like this.
But overall, the process is tedious. When you increase track width, then the actual clearance gets narrower, and you will violate clearance rules. And cleaning that up is a lot of work.
Seems a tad picky? I’d ask them if they could work with it this time and you’ll just keep this in mind for the next board. 10 mils is still pretty standard and not all that small by today’s standards.
Even our favorite inexpensive place seems to handle tracks much smaller.
Min. track width and spacing (1 oz)
0.10 / 0.10 mm (4 / 4 mil)
How about this:
I Selected desired Cu-Layer, Hide all other Layers
I Selected all Tracks and Changed their Widths…
Naturally, could have selected specific individual or groups of Tracks…
Added Demo of Specific 0.25mm Width to 0.3mm Width
It’s really tedious. I manually deleted the 0.25mm traces, but some hidden pieces remained in the component pads. With your tip, the rest was modified from 0.25 to 0.3. This way I can reroute without losing the larger traces. Thank you.
Just out of curiosity, I modified the traces from 0.3mm to 10mm, and dozens of large bubbles popped up on the PCB. I found it easier to remove the 0.25mm pieces after changing to 10mm.
