[PCB_FORUM] Re: Purge Via List

If you have planes on the board, you may have to move the associated
shapes off-board temporarily, as isolated vias tend to get associated
with them and thus have a signal name associated.

Hi Chandra,

 

Looks like you are using Studio. One other way to delete unconnected
vias is.

 

Edit -> Properties

Go to the Find Tab and in the Find By Name section Click More

Choose Net as Object type 

Click All

Click OK 

In the Available Properties Click on Fixed.

Click Apply.

You have now fixed all nets and their attached components.

Now you can do a delete of vias over the whole board and any via that is
not connected to a net will be deleted.

Once you have deleted the vias, unfix the nets by following the same
steps as above.
