I would very much appreciate any advice on the best way to divide a circle into three equal segments, such as the one that can be seen here: http://www.visualfractions.com/EnterCircle.html. I need to divide the circle with Object > Path > Divide objects below.

Thanks!

    Thanks Kurt! You are so smart.

    I'll give it a go.

    I did try Transform first. I just did not come up with the right numbers.

    I used the Transform effect, Kathryn.

    1) Draw a circle, diameter: 3 mm

    2) Effect > Distort and Transform > Transform:

    - Reference point: Bottom centre
    - Copies: 360
    - Scale horizontal: 100,4 %
    - Scale vertical: 100,4 %
    - Move horizontal: 6 mm
    - Rotate: 16°

    I love your yellow pattern design!
    Can you share some of your steps as to how you created that perfect spiral pattern?

    Thank you in advance.

    Office productivity programs like Office apps do not natively support vector formats beyond the OS meta formats like WMF and EMF. Office cannot use PDF as spot vector graphics. Nor does it import .ai files and translate their contents into native vector artwork.

    Office apps support the now rather dated EPS as an embedded or linked graphic object. But EPS assumes a PostScript printer, and is represented on screen and in non-PostScript print as the low-res raster preview it contains.

    So you can try exporting the vector artwork as EMF. Whether the results are satisfactory will depend upon the specific content involved. If you do not find it to be satisfactory, then you are stuck with a raster format, the most versatile of which nowadays is PNG because it includes lossless compression, is not limited to an indexed color depth, and supports alpha channel masking for so-called "transparency".

    By the way...

    I'm creating some simple icons to distinguish different type of sites from a client on the map of Europe. These icons, as well as the map of Europe, will be used in Word and Excel.

    Now that the icons are ready (in Illustrator), when I convert them to .png or .bmp (to be used in Word and Excel), they look completely pixelated. Is there any other format that I can use to preserve the vector images and the transparencies? Or is there something I should do in Illustrator before converting them into .png or .bmp?

    Thanks!

    OK Jacob:

    With the Ellipse tool make a circle (e.g. W- 50pt, H- 50 pt).

    With the Polygon Tool make a larger 6 sided polygon (e.g. radius 50pt).

    With View> Smart Guides on (Ctrl + u) and the polygon selected, use the Direct Select Tool (white arrow) to click drag the polygon by one of its anchors to the center of the circle. Smart Guides will say center when you are on.

    Select both the circle and the polygon and alt + click Intersect shape areas (top row, three from left) in the Pathfinder Palette. Now you have one piece.

    Select the piece, select the Rotate Tool and alt + click the center anchor point. Enter 120 deg and click copy. Repeat this by Ctrl + D to get the third piece.

    The thread lives.

    There must be other ways.

    Here's an idea...
    1. Draw your circle.
    2. Activate your star tool. Draw a 3 point star.
    3. Place your 3 point star exactly inside your circle, where the points touch the circle.
    4. Get out your scissors tool. Clip each segment at the point.
    5. Delete the star. Voila! 3 perfect segments.

    > That would be Rotate Tool in step 8?

    Oops. Yep.
