# Polygon w radius corners, aka 6 cornered rectangle with radii?

Hi Folks,

CS5/Win is the platform.

I have a "calendar" design that must have groups of days outlined (generally considered a "rectangle with rounded corners"), however due to the calendar sometimes the days being "outlined" are on separate rows. Picture regular corners in the upper left and upper right corner, but the row of the "bottom left" and "bottom right" are not the same. Generally the "bottom left" is one row lower than the "bottom right". Imagine the lower row looking like a "stair step" with one step.

The problem seems to be that when drawing a "rectangle" with more than 4 corners, some type of "radius management" is occurring, and one corner's radius gets changed (reduced) so that the radii are inconsistent in the object.

Has anyone else experienced this? Any workarounds? FWIW, the available distance between the two corners (one of which is affected) does have adequate distance to create the expected radius...

Help, anybody?

How about telling us how you are making these shapes? Are you trying to use the "LIve Corner Effects" to add the rounded corners? Do you want a radius on the "inside" corner of the step?

Is the effect that you are seeing with the corner radii, due to an irregular hexagon?

I've used various methods but the pen tool has been the best for making these more unusual boxes. After drawing the stairstep box with the pen tool and closing the path, I then choose Object->Corner Options, set the corner type as "rounded" and set the radius value. Of course, the Corner Options box only provides radii setting for four corners, so that could be an issue. And yes, both inside corners and outside corners should have a consistent radius value.

The problem areas are shown with red circles in the image provided.

Just hold the shift key while dragging.

I always do use the shift key when dragging, but when simply drawing with pen tool (click, click, click, not click & drag) then applying corner effects, there is no dragging, but this is when the irregular corner radii are presented.

I am able to reproduce this, but it seems to only happen when you reach a certain threshold relative to the size of the sides on your shape. My suspicion is it is realted tot he way live corner effects are handled (you can't, for example,  get a true pair of .25" radii corners on a .5" dimension using corner effects -- ID just won't go beyond the max radius that will allow the small required flat spot between corners), which is different from the way corners were handled in previous versions. I think you may need to adtually draw the curves yourself with the pen, or go through a fairly complex series of pathfinder operations to combine various rounded and square cornered rectangles:

The cyan, magenta and yellow shapes were alldrawn with the rectangle tool, then seleted together and a corner option applied. Use the pathfinder to combine the Cyan, Yellow and Green shapes, then subtract the Magenta from the combined shape in a second step. Colors are for illustration only -- you dont need fills for this to work.

For what it's worth, I think it may look better visually if the inside corner has a smaller radius, but you can combine things any way you like using this method.

That worked really well, thanks!
