Arrow Heads on Rounded Rectangles


When I draw a Round Rectangle in PowerCADD on the X, Y axis it looks correct. However, when I rotate the Round Rectangle it now renders to screen with arrow heads. Why did this happen and how do I fix it?

It is possible to assign an arrow style to a Round Rectangle after it's drawn. You can also assign arrow attributes to the Round Rectangle Tool itself. The same rules hold true for Rotated Rectangles and other PowerCADD objects.

Round Rectangles typically do not render to screen with arrow styles. There is, however, a unique condition that occurs when a Round Rectangles is rotated -- it becomes a Polygon. The Polygon is composed of numerous vertices which follow the shape of the original Round Rectangle. Like all closed polygons, there is a start point and an end point which are in the same X, Y position (obviously required to close the shape).

How could this happen?

There are two typical situations which can cause this condition. First, the Round Rectangle was accidentally assigned an arrow attribute after it was created. This might happen by using the PowerCADD Eye Dropper Tool, or WildTOOLs Needle Tool and you accidentally clicked on the Round Rectangle in the drawing. Another common situation is the object may have been accidentally selected as part of other objects to which the arrow style needed to be applied. Second, arrow attributes could have been assigned to the Round Rectangle Tool before drawing. In either case, you will not see the problem when a Round Rectangle is drawn on the X,Y axis since, when on axis, it is not described with the start and end points like a Polygon.

What to do

The fix is easy and there are two choices:

  1. Select the Round Rectangle object that was rotated and exhibits the problem (which is now a Polygon) and assign an Arrow pattern of none.
  2. Double click on the Round Rectangle Tool in the Tool Palette (this will deselect all objects) and make sure the tool is assigned an arrow style of none.

quicktime We've prepared this quick demonstration movie (1.7MB download) which shows many of the various conditions and the fixes. In this demonstration movie we are pressing the Control key and clicking on the objects or tool palette to assign attributes but you can also use the Default Window, Attributes Window or Attributes menu. In the end, it comes down to PowerCADD showing you exactly what attributes were assigned for the type of object created. (need movie help?)

We hope that helps
