You might get away with Orcad (cadence) Layout. You can get a student version and I don't think the limitations will hurt you. I don't recall the Layout limitations.
The overlay you refer to is know as the silkscreen layer. You can also do an outline layer and create custom layers.
Terry Pinnel has a page on CAD programs you should check. If he doesn't chime in soon, I think the URL is something like
formatting link
and part of that googled ought to return the URL if I'm wrong.
I'm hoping someone can give a noob some direction here. I've started designing a pcb using electronics workbench and am a bit confused on how to get past where I am.
I'm trying to create a component for a lumberg part (2415_01, 1502_01 and
2410_01) which are upright (vertical) usb, IEEE1394 and 2.5mm jack connectors. When creating a new component it gives me a option of choosing a standard footprint. I can't find a listing of these and I find one that works with this. I also can't see where to create a new footprint.
Thanks for the feedback - I also have access to powerpcb - is that much better?
There are two things I need in a pcb design package - easy ability to create custom decals/footprints as I am using some very specific parts and secondly I need to overlay a CAD drawing of the board as I need to be VERY specific in the layout of the components. Its a double sided board so two cad drawings would be perfect.
Products like Eagle just don't suppor this sort of thing (that I've foudn so far)
Now WHY would I say anything, Capture is JUST SO INTUITIVE ;-)

I love to cook with wine. Sometimes I even put it in the food.
Eagle will let you do most of that out of the box (so to speak). It does do custom footprints (and various silkscreen layers). I found it easy to create a new package. Weakness on new package layouts, circular holes only for through hole (If you need a slot you have to build it up). There are probably other weakness but for straightforward double sided boards I doubt you will notice.
As far as CAD overlay. There is support in Eagle to allow it but how easy it is to do I don't know. Check out the DXF importing utilities on their website (they also have support newsgroups). I think it should be possible to import a dxf into an unused layer and use that as a guide, but I haven't done it. Ask in their support newsgroups someone may have done it.
Again check for DXF import utilities on Cadsofts support area. There is/are some image import utility/ies as well but I didn't much care for the result lasr time I tried.
I've not had a problem with placing on as fine a grid as is unreasonable. (and in fact you can also position using absolute coordinates from the keyboard, very useful when trying to match existing mechanicals)
I also need the silkscreen layer but that's separate. I was referring to the outline layer. The problem is most entry level progs don't let you import files for the layers.
Other progs don't let you specify the location of the components precisely outside of the 2.54mm grid.

You probably don't, if you have lost the original files. In any case, why do you want to restore cookies? By and large, they are a menace. I spray them with cookie-killer from time to time. They should be called 'roaches', not 'cookies'. In any case, in UK they should be 'biscuits'. (;-)

It's a minor PITA to have to re-subscribe to newspaper sites and so on, but of course you can just restore the files if you have them backed up.
I don't know how you restore those handy little buttons and customizable icons on the top bar of IE. Probably you don't.

That's the downside. Cookies are frivolous or malign. Serious organizations that use them should be less ignorant.
I have to work with a site that is very important to me that uses all sorts of weird third-party tools, including stuff that Microsoft doesn't support in IE6. It's causing me endless problems, since February this year when I had to start using it.

I get the choice to start a blank project or one based on an original design and the default for the latter is heirachical.opj, which I know give me a page with the heirachical block and another (?)(blank?) page.
But is there anything in this type of project that isn't obvious at first glance?
What you are looking for is any package that imports DXF's (or DWG's). Do mechanical in mechanical, electriconic in electronic.
Import you board outline, slots, and other sundry non electronic component pcb holes etc.,from a mech. cad package (Autocad or a clone) as one layer. Do your 'tronic work on other layers - however many you need.
Lots of cad packages do this. They are not expensive. See Terry Pinnells website for a mega list of 'tronic cad and download some demo's. EasyPC will do all you need here for about $160 but there are loads more. Do not spend a fortune on an 'all singing all dancing' package if you are not going to use it regularly - you will spend hours, days, weeks, every time just trying to figure out how to do something in some of the more complex packages such as Cadstar, Pads etc. If you use them very regularly they are good otherwise they are worse than hopeless.
That's the minimum res with which I could comfortably use SS, IIRC. It's what I'm set at now. SS is only *one* of the screen consumptive apps I run, well, ran it a couple times, anyway.
Would you deign to provide enlightenment, or are you just throwing insults around for kicks?

If you have already drawn the schematic than do the following:
As an example I am assuming that you want to change the font for all part values for instance.
CTRL-A select all CTRL-E Mickey Mouse property editor will open Select Parts tab Left click on the Value header Right click and select Display Change whatever you like in there. If appropriate font size does not show than type it in.
If you are starting a new design than go to Options, Design Template
