With all this in mind, is there a way to select a group of polygons, lines,
etc... and lock them all at once? I can't seem to find anything in the
documentation, although I have a feeling that there's probably something
along the lines of lock(selectedpolys) available from the command line.
The polygon is cut into many polygons, such that there are no holes
that need to be erased.
So some of your polygons overlap?
I'm probably making a bigger deal out of this than I need to: I just have
this board that I helped redesign in PCB, and I want to make sure it's
right before I get it
Hello all,
Earlier this week, I posted a message asking how I could combine several
polygons in the ground plane into one larger polygon. I have heard nothing
back since I've posted, even though the list has been busy this week. If my
question is a stupid one, I wish someone would tell me why.
The answer is: it depends upon what you want to do. Do you want a
group operation, so that you can select a bunch of individual polys,
and create a logical grouping of them so they all become part of a
larger group which you can select and move?
That's exactly it. I can certainly understand
Ok, so the solder mask is a coating, and if I choose I could simply order a
board without one. I suppose the advantages would be that it (obviously)
keeps you from soldering where you shouldn't, and also keeps the board clean
looking and prevents corrosion. And I suppose that since I've already
Oh, maybe I should clarify: The pcb I am recreating has components with
square pads: that is what I am trying to do. I have done this by placing a
rectangle around a via in the component layer and also in the solder layer.
I am using the component layer as my top layer and the solder layer as my
Use the 'q' key to change pins/pads from round to square and back.
Oh okay: thanks. I guess I'd better go ahead and convert all of these vias
and my silk layer stuff to elements first.
Yup.
Okay then. I know what to do about the ground plane now.
Thanks much,
Jeremy
Hello,
I'm working on recreating a printed circuit board from a screenshot, and --
having aligned all the vias and traces as closely as I could with the
original artwork -- would like to recreate the ground plane by hand.
However, I can't seem to keep get polygons to stick, for lack of a better
Ok, after an astoundingly short (five minute) search, I found the solution
to the polygon problem: whoops. RTFM, I suppose.
However, my other two questions still stand:
Also, this is a two layer board: the top layer traces are in the component
layer, and the bottom layer traces are in the
Well, technically the almost all the vias are going to have something
soldered into them: I had to create all of the elements for the PCB by hand,
and instead of creating real elements I just drew outlines in the silk
layer and placed vias where pins will go. The documentation says this is a
bad
Hello,
I am trying to redraw the artwork for a 3.1 by 1.65 printed circuit board
in PCB. I am using a background image to help with this process, so I scale
the size of the board in PCB to 3.1x1.64 (which obviously also scales the
background image) and then draw an outline around this picture
I used method #1, and I also turned off the auto-scaling option in adobe
(whoops). This brings the measurements closer, but I'll need a better
printer, a better ruler, and better eyeballs before I can be sure the
measurements are just right.
To get back to my original question: If I crop the

I'm trying to unlock a board that was originally done in ExpressPCB, by

problem is that I have never designed a circuit before, let alone
Oh. I didn't even know I could do that. Thanks, I'll try and set that up.

Hello,
Some of you gave me great advice when I posted an earlier thread about the

I understand how you feel, but with these particular guys at
least...they're very down-to-earth. Every one of them has shown a
real willingness to help people, even newbies, whenever possible.
Well that's good. I'll be sure to pay close attention to their suggestions.

So to recap:
- It looks like my best option here is to create real schematics myself
using the tech reference on the MilesTag site, and then lay out the PCB
myself in PCB. Sounds fair enough. Do you think the auto-router could handle

Yes, I must have meant auto-place, which is a feature I have yet to try.
Right. So the toner transfer method sounds like the one I ought to try. Is
it fairly accurate for two sided boards? I'm assuming you guys mostly make
two sided boards, so I suppose that's a yes, but I thought I'd ask
Unfortunately space is at a premium in laser tag guns, so hopefully I can
make it work. I'm not sure I'd even want to attempt an SMT board at home.
Reflowing sounds a bit tricky.
Oh. I haven't met the guy yet. However, there is a machine shop here at
school and I know the teacher who runs it.
So it's possible to hand solder or reflow these things at home? Better yet,
can you do double sided SMT boards? I always thought you coudn't do it
because you would have to have components touching the surface of the reflow
skillet on one side while the other side was supposed to reflow. Also, am
