Corner Rounding

Corner rounding options :

Round corners: or .

If this box is checked ( ), radiused corners as defined by the field Radius will be applied to the most recently located point at the time you left-click ( Locate ) to define the next point. For hatches or fills defined by drawing an area box, Round corners (when checked) applies the Radius to all four corners.

If the box is not checked ( ), then pointed corners will be generated. The vertex of the corner will be where you left-click ( Locate ) to define the point.

Radius: A distance that defines the amount of rounding that takes place when the box is checked for Round corners.

The corner radius is the radius of a circle. Two lines that are tangent to that circle meet at the located point. The corner's arc ends at the points of tangency of these two lines.
  • A larger Radius designates a larger corner arc.
  • You can set a different Radius for each corner you lay out. For instance, if 1/2 is entered when you locate corner point C, but before you locate corner point D you input 1 as a radius, then a corner radius of 1 will be applied to corner point C.
  • Increasing the size of the Radius moves the edge of the rounded corner back from the corner point. This is because the Radius defines a circle that is tangent to both lines to the corner point. The arc of the rounded corner begins and ends at the tangent points.

Examples of corner rounding :

Two fills added using Hatches Add Define Polygon . Corner rounding was turned on for the left example. The radius for each corner was 1/2 the distance of any side of the square, which thus resulted in a circle.

The Cut Layout on the left has four points laid out in a square, but the result is a circle since corner rounding is checked AND the radius for corner rounding is 1/2 the distance of any side of the square.
