Multiple hole resizing in Altium Designer

Image

Altium has a convenient, but little bit hidden instrument for bunch changing of hole sizes.

Example

I have got a draft boards with some vias different vias, so let's look at the all existing (include in footprints) in this board hole sizes, what especially useful, when you get PCB design as is:ImageImage

Go to Panels -> PCB -> Hole Size Editor:

Image

Now you can see all hole sizes (including slots):

Image

Each via could be revised, so you can catch unusual or unwanted element:

Image

If you won't review and change vias in footprints change Condition Primitive Type to Show Vias:

Image

Usually, in the simple board used not too many types of vias, typically:

  • 0.3/0.6
  • 0.2/0.4

Image

So, you can see in this board some strange value. Some too small (0.1 mm, 0.175 mm) should be violated during DRC, because typical PCB. Another has non-standard value, this means more likely on the factory they will be changed to closest value, maybe with question from manufacturer.

Templates for vias

For clear board it's recommended to use templates (v60h30, v40h20) for vias and don't do not produce many different values unnecessarily. Another window will help to review and change all existing via templates in Pad & Via Templates:
