In the first section of the Steam Iron Product Design tutorial the base of the Steam Iron design was created using the Lofting Through Profiles solid modelling technique. This second section uses the Extrude Profile and Round Edges technique to produce the temperature controller.

The snapshot opposite shows the target design for this section of the Product Design Tutorial.

 
   
 
   
 
 
  Step 1    
    Open the file: loft process

Create a sketch on the underside of the iron called iron base. This sketch will be used to create an offset workplane that contains the sketch for the temperature controller.
   
 
  Step 2    
    Create an Offset workplane at -20mm from the Iron Base sketch.

Create a new sketch called temperature controller.
 
 
 
  Step 3    
    Change the viewpoint to Trimetric.

From the pull down menu select: Workplane and Reverse to flip the workplane to a 'face up' position.
   
 
  Step 4    
    Change the viewpoint to Onto Workplane. Select the 5th vertical line from the right, RC and select Project. RC again and select Toggle Construction. This line will be used to position the circle to produce the Temperature Controller.
 
 
 
  Step 5    
    From the pull down menu select: Workplane and Reposition Axes.

Move the cursor to the Mid Point of the line and LC to reposition the axes to the centre of the line.
   
 
  Step 6    
    Select the Circle icon from the Design Toolbar and draw a circle from the 0,0 position of the green axis (the cursor will snap to Mid Point). Attach a diameter dimension to the circle. Pick Select Constraints and Double Left Click (DLC) on the dimension and change the value to 45mm.
 
 
 
  Step 7    
    Return to a Trimetric viewpoint.

From the pull down menu select: Feature and Extrude Profile. Set the Distance to 17mm Above Workplane. Select OK to complete the command.
   
 
  Step 8    
    Pick Select Face from the Design Toolbar to filter out the line detail.

The snapshot shows the cylinder created from the 45mm circle. The cylinder feature will be further developed to create the finger recesses of the temperature controller.
 
 
 
  Step 9    
    Pick the Select Edge icon from the design toolbar and select the top edge of the cylinder.

From the pull down menu select: Feature and Round Edge, set the Radius to 5mm and click on OK to complete the command.
