    Shapes with curved sides

    Karl- Level 1

      I think I might be (hopefully) working too hard....

       

      I know I can draw a triangle with the polygon tool. But I want the sides of my triangle to be curved (both concaved and convex). Is their an easy way to achieve this?  Or do I have to use the arc tool?  (I also need a pin cushion shape. So hopefully the same technique works with the rectangle tool too?)

       

      (Or if I have to use the arc tool and draw individual lines, is there a tool in Photoshop or Fireworks that would make this easier?)

       

      TIA.

          Karl,

           

          The pin cushion shape may be created using the Effect>Warp>Bulge with negative value, first horizontally then vertically, or in reverse order. Positive value for actual bulging.

           

          Bulge does not work as nicely with a triangle. Maybe new options have emerged since 10.

            Found what I (at least) need....

             

             

            Object -> Envelope Distort -> Make with Warp

              On the Triangle try the Warp>Inflate and use a neg. number.

                As far as I can see, all options result in different curvatures for horizontal/vertical and slanting sides, at least in 10, so that it will look funny for a triangle even if you use different valus for horizontal and vertical bend/whatever, including different curvatures at either end of slanting lines.

                 

                Has that changed?

                  To find the centroid (geometric center) of a triangle (or any other path, for that matter):

                   

                  1. Copy.

                  2. Paste In Front.

                  3. Object>Path>Average.

                  4. Snap a horizontal and a vertical Ruler Guide to the position of the points.

                  5. Delete.

                  6.Use the intersection of the two Guides as the center of scale transformations on the points and/or the handles (Object>Select>Handles).

                   

                  Here's a method for making your bulging triangle using Transform Effect:

                   

                   

                  After step 7, an alternative way to join the figure into one path is: Expand Appearance, Ungroup, Divide Pathfinder. (The Pathfinder will stupidly remove the fill and stroke.)

                    James,

                     

                    When will step 7 be released?
