Working with Corners in CorelDRAW Designer

Modifying corners in CorelDraw drawings are easy and simple even when working on more than two combined objects.

Before beginning, display the Grid in order to facilitate accurate positioning and editing.  Click View then Grid or press F10.

In this example, three rounded squares will be welded together as depicted on the voltage adapter below.

Step 1: Modify the corners of Square Objects

1. Select the Square object using the Pick Tool. 
2. On the Property Bar, select Rounded, Chamfered, or Scalloped Corner. 
3. Set the Corner Radius.  Use the Edit Corners Together padlock to set the same corner radius for all corners.

Step 2: Position the Square objects and weld them together

1. Fill all the three squares with any color using the Palette and change the thickness of the Outline using the Outline Pen so it is more visible. 
2. Align the squares to form a pyramid.  Use the grid to ensure consistency. 
3. Click Window then Shaping to display the Shaping Dock. 
4. In the Shaping Dock, select Weld from the list. 
5. Select the top square using the Pick Tool.  Click the Indicate Target button on the Shaping Dock.  The two objects are now welded together while retaining the rounded corners.

Step 3: Modify the curves to create reverse corner

1. Zoom in to the corner where the two squares had been welded. 

2. Select the Shape Tool on the Toolbox. 

3. Using the Shape Tool create two nodes equidistant from the corner.  Right-click and then click Add Node.  Alternately, use the Add Node button on the Property Bar. 

4. Select the single node on the corner.  Right-click and Delete Node.  Alternately, use the Delete Node button on the Property Bar.  With the corner node deleted, there is now a straight line running between the two nodes created in Step 3. 

4. Using the Shape Tool, right-click on the line between the two nodes creates in Step 3. Click Convert to Curve. 

5. Drag the curve in line with the top square.  Use the control arrows of the two nodes to modify the smoothness of the curve as needed.

The corners of the top square now flow into the lower-left square.
