Need help with eagle cad, quick question for newbie

[kevilay]

Hey guys I just started making schematics on eagle cad. Ive used other programs before but decided to try this. So far its pretty awesome. To my question, how to I make a reference point to keep my schematic clean? And how to i make the little wire loop so I know crossing wires are not connected? Here is the schematic I am trying to copy. The reference I am talking about is the VB. Also what kind of terminals does it use for in and out? I was using test points, is there anything better? As for the supply, Im using V+ and V-, is there a 9V and GND i could use? not that it really matters.

Thanks

Download and install the library at gaussmarkov's page here http://gaussmarkov.net/wordpress/tools/software/eagle/eagle-2-libraries/
He has in, out, +9v, -9v, GND, Voltage Bias and a whole bunch of connections gathered together.
Not sure how to draw in the overlap loop. Not even sure that you can. When reading a schematic it is assumed that if two overlapping wires are not connected there will be no junction 'dot' on the connection, if they are connected there will be a  junction 'dot'.

If you click the ERC (electrical rule check) button in the left toolbar next to the yellow exclamation mark button it will notify you of all junctions of more than 3 wires where you forgot to add the dot

The Supply 1 and 2 libraries have +9 and Ground.
There is a curved tool next to the wire tool, that's how you can make the curved jumps over crossing wires like you're describing. 
The In and Out are done with the pads in the Wire Pad library.

The Supply 1 and 2 libraries have +9 and Ground.

One of them also contains a "1/2VCC" supply ref, which is what I use for VB.

Also, use 'Net' when making component connections, not 'Wire'.
Not very intuitive, I know, but I used to have missing junctions all the time and it was because I used 'Wire'.
I learned that from Gauss Markov's site, good reading there.
In fact, I recommend reading the whole thing while you're tinkering with Eagle.

then thats exactly what I will do. I started routing my board yesterday and ran into a weird issue. Cant delete a mistaken route... have to do some research on that one. Now I just need to learn how to properly place items in the most efficient way and route them the best way. Is there tips and guides to doing this? I definitely have alot to learn.

One more thing. How difficult is it to create my own items. I have a hell of a time finding some items sometimes, Id love to make a generic Diode, Polarized cap and Regular cap. Knowing that in guitar circuits their almost always the same size. I had some issues finding a regular size diode. Im sure ill figure this all out in time tho

Thanks for the responses

+1 for the GM site.  It really opened up the app for me and his libraries are the best.  Keep the default libraries at hand as you may need to find parts from time to time (I had to find a CD4007 today).  His tutorial on ground pours is superb and it's well worth the time to read the articles in order.  Brian over at Madbean is threatening to do some tutorials which would be nice because his are some of the nicest docs in the business but I suspect he's a tad busy these days.

Cant delete a mistaken route...

In the toolbar on the left there is an option called 'Ripup' right beside 'Route', just click on the mistaken route and it will return to a wire/net. You can also use it to hide the ground pour by clicking on the Polygon outline.
