        We have decided to release the new Parts Editor in two phases.
        The first phase, included in release 0.7.9, is already easier to
        use&nbsp; and more powerful than the old Parts Editor, but you
        still have to do a lot of preliminary work using an SVG editor
        like Inkscape, Illustrator, or CorelDRAW. In the next phase we
        hope to eliminate much of the need to use these programs.<br>
        <br>
        <big><big><b>How to start</b></big></big><br>
        <br>
        The new approach is very different from that of the old Parts
        Editor, and explaining that difference is the purpose of this
        document. The first big change is that you cannot create a new
        part from scratch--you must begin with a part that already
        exists. So the best thing to do is to find a part that is pretty
        close to what you eventually want. If your part is really
        different from anything else, then just to try to match the
        number of connectors. For example, if your part needs 39 pins,
        then start with a generic IC part, change it to a SIP (single
        inline package) and give it 39 pins. Though finding a part to
        begin with may seem like a burden, it will save you effort as
        you go through the process.<br>
        <br>
        You can open the new parts editor by right-clicking a part in a
        sketch and choosing the 'Edit' option; choosing 'Edit' from the
        Part menu; right clicking a part in the Parts Bin and choosing
        the 'Edit' option; or using the Parts Bin drop down menu.<br>
        <br>
        <big><big><b>Six views</b></big></big><br>
        <br>
        The new Parts Editor no longer tries to display everything in a
        single view.&nbsp; Instead, it works like the sketch window
        which has multiple tabs with only one tab visible at a
        time.&nbsp; In the new Parts Editor there are six tabs:
        Breadboard view, Schematic view, PCB view, Icon view, Metadata
        view, and Connectors view. As you might expect, the first four
        views are for the part images; the Metadata view is where you
        enter the part's title, author, and other properties; and the
        Connectors view is for editing connector metadata, and for
        adding or removing connectors. For the latter, you just type in
        the number of connectors you want.<br>
        <big><big><br>
            <b>Loading new images</b></big></big><br>
        <br>
        To load the SVGs for your part, switch to the appropriate view,
        and use <b>File &gt; Load image for view</b>. As before, you
        can load SVGs in all views and gEDA .fp files and KICAD .mod
        files in PCB view only. To create an SVG for any view, you must
        use an external SVG editor (Inkscape, Illustrator, CorelDRAW, or
        a text editor) to layout the elements that will be used as
        connectors. The SVG example below uses &lt;circle&gt; elements
        for connectors.<br>
        <br>
        Loading PNG or JPG images directly is possible, but since these
        become SVG images with only a single element, there is no way to
        place individual connectors. We also&nbsp; discourage the use of
        PNG and JPG because these are raster-based rather than
        vector-based, so they don't look good when scaled. If you still
        prefer to use PNG or JPG, we recommend that for now you open
        them in an external SVG editor and add connector elements there
        (see below for more about 'connector elements'). Save the result
        as an SVG, and use that in the Parts Editor.&nbsp; In phase 2
        you will be able to add connector elements directly in the Parts
        Editor.<br>
        <br>
        Since you have already begun with a part, it may be that you
        will only have to load a single image for a particular view--you
        do not have to replace all the images in the original part.<br>
        <br>
        It is still necessary to prepare SVGs for PCB view by grouping
        elements in layers: copper0, silkscreen, copper1, etc. (Layering
        will be handled in the phase 2 parts editor.) The best way to
        understand the layers is to open up one of the core pcb svg
        files, For example have a look at the file crystal_hc49U.svg.
        Silkscreen layer has four while lines, the two copper layers
        share a pair of circles as connector elements.<br>

        <br>
        Sometimes you will want to reuse the breadboard image as your
        icon image. There is a shortcut for this under <b>File &gt;
          Reuse breadboard image</b>. You can also find the options: <b>File


          &gt; Reuse schematic image</b>, and <b>File &gt; Reuse PCB
          image</b>. <br>
        <br>
        For certain parts--like a breadboard--there is only one view
        image. For technical reasons, you have to tell the Parts Editor
        this is what you want.&nbsp; Use <b>View &gt; Make only this
          view visible</b> from the current view (one of Breadboard,
        Schematic, or PCB) to make the part invisible in the other two
        views.<br>
        <br>
        <big><big><b>Undo, save, show in folder</b></big></big><br>
        <br>
        The next big difference from the old Parts Editor is that undo
        is always available, even after loading view images.
        Furthermore, you can save your changes at any point and keep
        working--the new Parts Editor is less like a dialog and more
        like a full document window.<br>
        <br>
        If you start with a core part (i.e. a part from the Fritzing
        distro), saving from the Parts Editor is disabled. You must use
        <b>Save as new part</b>, because you cannot change a core part.
        <b>Save as new part</b> creates a new part in your local storage
        area (explained below) and this part is added to the "My Parts"
        Bin--it is a copy of the original part (plus whatever changes
        you have already made so far using the Parts Editor). If you are
        editing a custom part that was in a sketch, the part will be
        updated whenever you save. If you want the new part to display
        in the My Parts Bin the next time you run Fritzing, remember to
        save the bin (use the drop down menu at the upper left of the
        bin). If you start editing from a part in the My Parts Bin you
        have a choice between <b>Save </b>(which will overwrite the
        part), and <b>Save As New Part</b> (which will create a new
        part and add it to the My Parts Bin). If you copy a part into My
        Parts Bin from some other bin, then probably <b>Save </b>will
        be disabled.<br>
        <br>
        On Windows the local storage folder is something like
        C:\Users\[username]\AppData\Roaming\Fritzing\parts\user\, and
        SVGs are stored in
        C:\Users\[username]\AppData\Roaming\Fritzing\parts\svg\user\. On
        Linux and Mac this would be ~/.config/Fritzing/parts/user/ and
        ~/.config/Fritzing/parts/svg/user/. <br>
        <br>
        To find the SVG image for the current view on the desktop,
        choose <b>File &gt; Show in Folder</b>. On Mac and Windows this
        will open a folder on your desktop with the SVG file selected.
        Under Linux you get the folder but no file selection (if anyone
        has advice about how to get selection to work, we would be
        grateful).<br>
        <big><big><br>
            <b>Associating a connector with its SVG counterpart</b></big></big><br>
        <br>
        The next task will be to associate each connector with its
        counterpart in the SVG for each view. This is handled very
        differently from before. For an example, I am going to use
        images from a part created by Shunichi Yamamoto (who graciously
        gave us permission to include them in this tutorial, and who
        also helped beta test the new Parts Editor).&nbsp; <br>
        <br>
        The new part will have 39 pins, so we begin with a Generic IC
        part and drag it into an empty sketch. There we use the
        Inspector to change it a to SIP and give it 39 pins. Then we
        open that in the new Parts Editor with a right-click.&nbsp; <br>
        <br>
        <img alt="starting up" src="images/start.png" height="363"
          width="599"><br>
        <br>
        Next we load the new breadboard image using <b>File &gt; Load
          image for view</b>.&nbsp; In the Tools widget at the upper
        right, you see a list of connectors. Choose one to make it the <b>current


        </b>or <b>active</b> <b>connector</b>. If it has already been
        associated with an SVG element, that element will display a
        marquee highlight. Since we are just starting out, we will
        choose pin1 which is not currently associated with any SVG
        element.<br>
        <br>
        <img alt="pin1" src="images/pin1.png" height="319" width="419"><br>
        <br>
        To create the actual association click the "Select graphic"
        button over in the Connectors widget. This basically puts you in
        a "mode" that lasts until the next time you mouse down. If you
        want to escape the mode, click anywhere outside the part or use
        the escape key. You can only make the association when you are
        in this mode (this keeps you from accidentally associating a
        connector to a graphic when you didn't intend to). <br>
        <br>
        In the mode, move your mouse over the SVG. As you do so,
        different SVG elements will highlight. It is often the case that
        any given mouse location can refer to multiple SVG elements (or
        groups of elements). Use the shift-key plus the mouse wheel to
        highlight other elements above or beneath the currently
        highlighted one (in the z-order)--the mouse wheel without the
        shift key will pan or zoom as usual (depending on your
        preferences setting for wheel events). If you are already on the
        bottom layer then the next wheel "downward" will make the
        element flash white; a similar white flash will occur if you are
        already at the top layer and wheel "upward". In other words, the
        flash signifies you can't move any further in the z-order in
        that direction.<br>
        <br>
        Here are three highlights from the same mouse position, using
        the mouse wheel + shift:<br>
        <br>
        <img alt="highlight1" src="images/highlight1.png" height="161"
          width="348"><br>
        <img alt="highlight2" src="images/highlight2.png" height="160"
          width="350"><br>
        <img alt="highlight3" src="images/highlight3.png" height="159"
          width="349"><br>
        <br>
        The first highlight is the one we want so we mouse down when the
        wheel gets us back to that small rectangle. Now the element has
        a marquee to show that it is the current pin, and you also see
        the <b>terminal point</b> as a crosshair which defaults to the
        center. The terminal point is the place where a wire attaches to
        the connector.<br>
        <br>
        <img alt="assoc1" src="images/assoc1.png" height="161"
          width="349"><br>
        <br>
        After associating pin2 and pin3 we have:<br>
        <br>
        <img alt="pin3" src="images/pin3.png" height="160" width="347"><br>
        <br>
        <big><big><b>Adjusting terminal points</b></big></big><br>
        <br>
        In PCB and Breadboard view the terminal point is usually the
        center of the connector so you don't have to do any thing
        else.&nbsp; But in schematic view the terminal point is usually
        near the end of the connector. So let's go to schematic
        view.&nbsp; We start with the original SVG image. Note how the
        connectors are already showing their anchor points. Pin3 is the
        current connector.<br>
        <br>
        <img alt="schematic" src="images/schematic1.png" height="573"
          width="718"><br>
        <br>
        Now we load the new schematic image and start associating pins.<br>
        <br>
        <img alt="schematic2" src="images/schematic2.png" height="640"
          width="519"><br>
        <br>
        Here is what the Connectors widget looks like with pin3 as the
        current connector:<br>
        <br>
        <img alt="tools1" src="images/tools1.png" height="463"
          width="348"><br>
        <br>
        Notice that since we have selected graphics for three of the
        connectors, those connectors are checked in the connector list.<br>
        <br>
        You can use the buttons or spinners to adjust the terminal
        point. Here is a close up after hitting the W button, and
        clicking the X spinner twice (look at the pin marked 'AN2'): <br>
        <br>
        <img alt="schematic3" src="images/schematic3.png" height="492"
          width="536"><br>
        <br>
        You can also drag the terminal point directly by mousing down on
        it when its SVG element is highlighted.<br>
        <big><big><br>
            <b>Setting internal connections</b></big></big><br>
        <br>
        An internal connection is when a two or more connectors in a
        part are already connected, for example the GND connectors on
        the Arduino UNO. You can specify and edit internal connections
        by clicking on the "Set internal connections" checkbox in the
        Connectors widget--it's beneath the connectors list (you can see
        it in the image of the Connectors widget, above). Since we are
        talking about the Arduino UNO, here is what it looks like when
        Set internal connections is checked:<br>
        <br>
        <img alt="bus1" src="images/bus1.png" height="319" width="419"><br>
        <br>
        The green lines represent the internal connections. To remove an
        internal connection, right-click the line and choose "Remove
        internal connection". To add a new connection, just drag a line
        out from one connector to another.<br>
        <b><br>
        </b><b><big><big>Known limitations</big></big></b><br>
        <br>
        The following feature are due in phase two: <br>
        <ul>
          <li>adding holes</li>
          <li>mixing THT and SMD connectors--for now you must start with
            an SMD part to create a new SMD part, and start with a

        you've seen. Stay tuned for phase two.<br>
