When I create a thick outline my square edges get cut off in CorelDraw

Here is our original image. You can see that all the corners are sharp. I have two 45 degree corners (1, 2) and I have 1 90 degree corner (3).

If I place a wider line on the original line my two 45 degree corners get cut off or mitered by Corel. This is no good for me so I need to change this.

Let us change the miter level so that Corel will not cut the corners. Select the Outline Pen tool (1).

To change the miter level we need to go into our outline pen dialog box. Select the Outline Pen dialog command from the menu.

Change the Width to 0.125 width (1). Change the Miter level to 44 degrees. Note: by default Corel will miter anything that is 45 degrees or less. By changing the miter level to 44 means that it will not adjust my 45 degree corners on my image.

You can see that my corners have not changed they are still the same. This is because I told CorelDraw not to miter any corners more than 44 degrees. I did this in the previous step. Thus if you find that you are creating thicker lines make sure that you also change the miter level so that the corners do not change.

If you want to set this as a default go to TOOLS (1) | OPTIONS (2)

Select Styles (1) and than Default Graphic (2)

Select Edit (1)

Change the miter level to say 1 (1) and click Ok (2).

Select Document (1). Than Save Options as Defaults (2). Than Styles (3). Than Click on OK (4).
