Robert,

I know what you mean about the help file. It isn't very deep. Going through the tutorial in the help file may help you get started.

When I am making schematic parts, I am usually in a hurry and don't try to make the part look like a symbol, I just put down the number of pins I need, name and number the pins, put a polyline rectangle around it to give it form, and name the part. That only takes a couple of minutes, and I can get on with the schematic.

If you wish to make a dual NPN that symbolically looks like two NPNs, that should be fairly simple. Let me see if I can walk you through it.

1) Once I enter the Part Editor, I first selected the NPN_EBC part from the Device library, and hit Copy beneath the Product column. In the window that pops up, I enter my personal library, and the new product name. After it is copied, I highlight my library and the new product and hit Select.
2) You should see a single NPN on the screen. I then zoom out once or twice by right clicking and hitting zoom out, just to make it easier to work on. You'll find that a lot of things are done by right clicking, which goes quickly once you get used to it.
3) Now left click and hold and draw a window around the part and release. Select copy from the menu that pops up. Now right click and select paste. Find a spot where you like the new copy and left click to drop it.
4) Next you can edit the pins. Put the crosshairs on the pin and right click and select modify. At the top of the screen you should see the pin properties. Change those as you need and hit modify.
...."edit the pins" is where i have the problem; new names and pin numbers do not "stick". See what i said i would like (E1,B1,C1, etc) and pin numbers as well (1...6).
That way, when i draw the schematic i can connect E2 to C1, B2 to V2, etc.


5) Since you only want one name and reference designator for the part, right click on the ones you don't want and hit Cut, unless you didn't copy those from the original in the first place.
6) That should get you a useable schematic symbol, so if you are done, hit File and Save Product to save it.
....i do not remember seeing File or Save in the editing,but did find that every change i made was saved (automatically?) so that does not make me concerned.


Now, if you were making a new part from scratch, you would use the items on the Object menu to place a pin or text or a polyline (that's the blue lines). Modifying them works as above. Hope this helps.
...did not get anywhere from scratch, so tried the copy schems which was very sucessful.

....Will go back to WinQcad and try some more as you suggest.

Do not mention Eagle, i wasted a lot of time on POTS to download the demo version, and again, it was totally useless.
And i was unable to figure out what files wer needed to make the DOS Orcad even run - so that is out.
PCB123 is out, because the manual is worse than obscene - unreadable (Acrobat sez it is corrupted and cannot fix it).
So what is left?


1) I downloaded the Vutrax "readme" and loader; VTXsetup.exe bitches about non-exiatant master files.
Ignore the fact that it was too dumb to *create* a folder, it certainly is incomplete if it cannot create those master files or "dial home" for them.
So, what do i do to get it installed (it should be simple and not require a lot of jumping thru hoops)?


2) I downloaded and sucessfully installed WinQcad. Seems to be useable, maybe.
I need to create a library (done) and add a dual NPN in a SOT-323 package (well, partly done).
The "part" has the schematic of two NPNs inside the box and oriented properly so one (theoretically) could draw connections from each element (E, B, C) to pins of the package, BUT...
I cannot add pins to the package, i cannot even number the element (assign pin numbers), i cannot change the labels (E1, B1, C1, E2, B2, C2).
The help document is not eXplicit enough to be of any help.
It was hard enough to figure out how to *copy* an NPN over to the new "part", and it was a PITA doing that, especially with no clue that closing "new part", opening NPN part, copy, close, open new part, paste, etc would not lose any old info - much less the hassle.
So, how do i make the darn "part" complete on the electronic dwg side?
And then, i presume more hassle on the dimensioninf side...
