How do I Create a Rectangle with a Filleted (radius) or Scallop Box in CorelDraw X3 or Higher
This article will discuss the technique involved in creating a Filleted box that we would use to cut out plates on a laser.
First of all we need to select the rectangle tool in CorelDraw
Select your rectangle tool by by clicking on the rectangle tool in the Tool Box. Your cursor will turn into a “plus”
Draw your rectangle
To draw the box hold your left mouse down and drag your mouse. Do not worry about the size
Size the Box
Let us say that we want to create a filleted box that is 1 by 3 in size. To do this first you need to type in 3 inches for the width (1) and 1 inch for the height (2)
Next we need to change our rectangle to 3 by 1 in size
Select the rectangle. We need to size the rectangle to say 3 by 1. To do this we can enter in the size via the property bar. First though we need to make sure that the lock button is unlocked (1). Next we need to enter in 3 for the width (2) and 1 for the height (3).
Here is the box as a 3 by 1
Our rectangle is now 3 by 1
Open up the Fillet Docker
Select WINDOW | DOCKERS | FILLET / SCALLOP / CHAMFER
Create a .25 inch Fillet
Select the rectangle (1). Select the Fillet (2). Select the Radius (3) in this case .25 inches. Than click the apply button (4).
Our rectangle now has a .25 inch fillet or radius
We now have a .25 inch fillet on our rectangle
How to create a Scallop edge
Click the undo button. We have our rectangle back. To do a scallop edge select the rectangle (1). Next select Scallop (2). Next select the radius of .15 (3). Click the apply button
Our Fillet is finished
Now we can cut out the filleted box on our laser
What about if we want to resize the scallop or filleted box?
As you can see from the image our first box in black has been resized to the red box. The scallop size has changed. Note: the rectangle has been made longer but not taller.
Resized Scallops
You can see from the image that the two scallops are different even though all I have done is stretched the rectangle out. I have not changed the height
Select the Shape tool
The easiest way to resize this rectangle is to stretch the rectangle via the nodes. To do this we need to activate the shape tool (1)
Activate the nodes on the rectangle
With your cursor now a black triangle click on the rectangle (1). You will have a number of nodes appear.
Select the nodes
While holding down your left mouse button draw a selection box around the 4 nodes on the right side
Nodes Selected
Our nodes are selected because they are solid black
Drag your selected nodes
Now while holding down the left mouse button drag the four selected nodes to the right. If you want to keep the line straight hold the ctrl key down as you drag. I have dragged the rectangle to the same width as the rectangle that i resized at the beginning, which is signified by the guideline.
Comparing the scallops
In this figure the black line (1) represents the original rectangle the red line (2) represents the original stretched rectangle the blur line (3) represents the rectangle stretched via the nodes. You can see that the radius has not changed based on the first rectangle when I use the nodes to stretch the rectangle on the blue rectangle
Note: In X5 you do not have to worry about this issue as when you stretch an object the radius will stay the same
