One way to use arcs and other odd shapes in iWork Apps
I love Keynote and Pages, and find the drawing tools useful for many things I need to draw, but not all. One common problem I have is that I need to draw arcs of circles, for instance when labeling angles in a geometry diagram, which I do a lot. PowerPoint has a tool to do this, but in iWork, the only way to do this is to draw it freehand, which doesn't produce very good results for me. I have, however, found a workaround.

Use the circle tool to draw a full circle that you can trim into the arc you are interested in. Set the color, fill and line style as you want (you won't be able to change it later). Cut or copy the circle into the clipboard. Switch to Preview.app and create a new document (Command-N); a window will open up containing a PDF of what was in your clipboard (i.e. your circle). Copy this PDF to your clipboard (just hit Command-C, and it will copy the entire image) and paste it into Keynote (or Pages). You've now replaced your Keynote-created object with an identical object in PDF format.

Select the free hand drawing tool (or any of the other drawing tools) and draw an object that overlaps your circle such that the overlapping region contains just the arc you want to keep. Now select the PDF circle and your drawing and use the "Mask image with selected shape" function (Command-Shift-M), and you will be left with just the arc.

You could use the same steps to cut other standard shapes into segments as well. Hopefully this will be a helpful workaround for some of you until Apple adds more drawing tools to iWork.

One way to use arcs and other odd shapes in iWork

If you do not need to use iWork there are better tools out there. For making diagrams I recommend OmniGraffle, www.omnigroup.com/applications/omnigraffle/, by the OmniGroup. It's however not free software. If you do mostly geometry drawing check out GeoGebra, www.geogebra.org, which is a Java based application. Really nice, can do lots of stuff and it's free for non-commerical use!

I assume this means that they haven't added arcs to the latest iWork version...grr. That feature might have motivated me to upgrade from '06.

I keep a copy of Appleworks around to draw arcs (one could use some other program). Another idea is to draw a circle in iWork, then use the freehand tool to draw the arc by making some points along the circle's edge; you don't need too many points to get a reasonable approximation. When done, select the curve, choose "Smooth path", and delete the circle. The advantage of this method is that you can change the style and color of the line.

I must say, for all diagrams and schematics, I use Intaglio... The only other app in the world that features the same autoalign graphical tags than Apple's ones, and I even wonder whether they didn't start before Apple.
Best GUI ever, IMHO.

Another method:

Draw a circle, with stroke and no fill. Draw two rectangles, with no stroke and white fill. Rotate/position the rectangles to crop the circle to the angle desired. Put other layers on top of them, such as your diagram's line segments.

If Powerpoint does it, couldn't you just draw it in PowerPoint and then copy it over. Or even AppleWorks, if you still have it.

If people are looking for something to do sketches and such - Rita is the best option I've found.

There's a few around, but most are *worse* than Microsoft Paint (Horrible to use, very rigid and hard to draw with).
Rita has decent drawing tools (It's actually possible to draw curved lines, unlike most other application I tried, where they would look like a series of 50px straight lines)

http://www.frykholm.se/rita.html is it's website - it's effectively free (It's not a 30-day trial or functionally-crippled), and you can pay $20 to register it

I do it this way in Keynote '08. Use "Draw a Shape" and click two points to form a line. Then click on the red circle of one point and drag to stretch to form an arc. Seems easy enough.

Easy enough to make a curve, but much harder to get a perfectly circular arc, hence the other workarounds.
