I have a line of text on the silk screen layer in PCB that I would
like to make bigger. I can't see how to increase the font size. I've
looked through the manual also.
How can I change the font size of text?

Key S should work
What is the standard refdes for a crystal, I'm blanking? The generic

I'm trying to re-route some traces in pcb. PCB is not letting me
route traces, even traces that are already there.
For example, there is a trace on the component side going to a pin of
a component. If I delete the last leg of the trace going to the pin,
optimize rats and try to
Is there a way to force pcb to select a very small trace coming from a
pin? Every time I try to select it I either select the pin or
nothing.

I submitted a 2 layer layout to 4pcb. The dfm reports missing solder
mask clearance for 8 vias that pcb inserted in the layout. When I
click on info in pcb shows the vias solder mask hole = 0.0.
Suggestions???

Maybe I should phrase that better, how do I add a solder mask
clearance to a vias that pcb added?
Thanks

I guess that k key function is on versions later than 20070208. I
select the via and hit k and nothing changes.

How do you switch on visibility of the solder mask?

I have a 2 layer home made board with laser diodes. We're having a
hard time getting the solder to flow from one side of the board to the
other to connect traces. Does anyone have any suggestions how to get
the solder to flow well to the component side?
Thanks
When you say a wire, are you talking hollow wire so that the component
can be inserted into the hole also? I'm not understanding. Does the
22ga wire lay beside the component lead? If that's the case all the
thru holes will be too small.
I hate to use the word assume but I
