    Default How to Divide Circle into Slices?

    I need to divide a circle shape into 8 slices (like you would slice a pizza pie into wedges). I saw instructions for this while ago, but can't for the life of me find them now. There was some kind of mathematical formula used, if I recall. Can anyone point me in the right direction or provide the steps here? Thank you!

    I would start by dragging two guidelines though the horizontal and vertical center of the circle.Then using the Shape Editor Tool (set to Line not curve) draw from the center a slice triangle. Click the last control point on top of the first to create a closed shape (it will fill black). Select both the slice shape and the circle and press Ctrl + 4 or Arrange > Combine Shapes > Slice Shapes.

    This will maintain the circle but create a new shape for the slice.

    Thanks. The instructions I'm looking for seemed more mathematical and allowed you to create very precise and equally portioned wedge slices just by changing the numerical value. I need to slice a circle into 8 exact wedges. There was a whole thread on it a long while back and I had saved the link, but when the forum got updated or whatever, none of my saved links worked any longer. Do you know anything about that?

    Draw a Circle
    Draw a vertical Line
    Set the 'Snap To Objects' to on
    Centre/Snap the line onto the centre of the Circle
    Clone the Line and enter 45 into the 'Angle of selection' box
    Select the line and the circle and apply 'Slice (cut) Shapes'

    Thanks for reposting this. After the horizontal and vertical guidelines are set, if I clone the vertical line, then enter 90 in the angle box on the infobar, the line does not match up with the horizon guide. It's just a little off. The line thickness is .25pt, it doesn't matter if the scale line widths button is on or off. I did check the help file and this doesn't seem to be covered. Also, does it matter if the 'cutting' line is drawn from the shape tool or the other line tools? Thanks for comments.

    Once you've drawn the circle and the line, you can select both and press and CTRL+SHIFT + L, and select Align centrally for Horizontal and Vertical positions. Click the Apply button.

    Then when the line is aligned centrally over the circle, now clone it, then rotate it.

    In the image attached, 'Apply' has not yet been clicked.

    Hi emcat. Here's an update that should make things clear to you. I've included the Xara.file so you can pull all a part, both beginning and finish. Hope it helps.
