You can make your clocks in wood, metal or plastics OR a combination of these materials. Above are some examples. The instructions below will help you model your clock in Pro/DESKTOP but BE WARNED - you may have to go back over some of the other worksheets to revise individual techniques.
Open a new design.
Click on Workplane then New Sketch. Type Clock Face into the Name box and Frontal in the Add to Workplane box.
Draw a circle of 140mm diameter.
Extrude the circle to 4mm.
Click on Select then Edges. Select the top edge of the disc. Click on Feature then Round Edges. Type 1 into the Radius box. Click on OK.
Click on Select then Faces. Highlight the top face of the disc.
Press Shift and W to go onto the workplane.
Click on Workplane then New Sketch. Type Time Marker into the Name box. Click OK.
Draw a circle of 6mm diameter in the "twelve o'clock" position on the clock face.
Click on Select then Lines and highlight the small circle.
Click on Edit then Duplicate. In the menu box that appears select Circular then type 12 into the Number box. Check that the angle box says 360 degrees and click on OK. Twelve circles should appear around the perimeter of the disc.
Extrude these circles to 2mm.
Click on Select then Edges. Hold down the Shift key and select all the top edges of the small circles.
Click on Feature then Round Edges. Type 2 into the Radius box. Click on OK.
Click on Select then Faces. Highlight the top face of the disc.
Click on Workplane then New Sketch. Type Hole into the Name box. Click OK.
Draw a circle of 10mm diameter exactly in the middle of the clock face (to do this select the circle tool and bring it towards the large circle. Click and drag inwards when a square lights up in the centre.)
Extrude this circle 4mm below the workplane subtracting material.
Save your design.
Open a new album and render your design.
To design a vacuum-formed clock you need to know how to use the Shell Solid tool. The page entitled Circuit Box shows you how to do this. Otherwise:
Open a new design.
Click on Workplane then New Sketch. Type Clock 1 into the Name box and Frontal in the Add to Workplane box.
Hold down Shift and press W to go onto the Workplane.
Use the drawing tools to design the shape of your clock. Use the scissors tool to ensure that you have a shape that can be extruded. Check this by clicking on Line then Toggle Sketch Filled. If you need help on any of the drawing techniques go back to worksheets 1 and 2.
Extrude the shape. You will need to extrude to about 40 or 50 mm. Make sure that you taper the sides slightly as vacuum-formed products need to have a "draw angle".
Round all the edges to 2 or 3 mm. (Vacuum-formed products tend to have no sharp edges.)
Roll the object around so that you can see the back.
Click on Select then Faces. Highlight the back face of the clock.
Click on Feature then Shell Solid. Type 2 into the Offsets box. Click on OK.
Add any other details that you require to the front of the clock.
Save your work.
These are relatively easy to shape. Use the first two worksheets to create the shape you want and if you need to add a clock face look at the worksheet on assembly procedures (ProDESKTOP 4).
This is probably the most difficult to draw. You have to design the profile or cross-section of the clock and extrude it from this as it is difficult to do it in any other way. (This is like the red clock in the pictures at the top of this sheet.)
Open a new design.
Click on Workplane then New Sketch. Type Clock Profile into the Name box and Lateral in the Add to Workplane box.
Press Shift and W to go onto the Workplane.
Draw a rectangle 180mm. high by 4mm. wide.
Click on Select then Lines. Highlight the rectangle.
Right click the mouse. A menu should appear. Click on Transform.
in the dialogue box, click on Rotate. Enter 20 into the Angle box. Click on OK. The rectangle should tilt by 20 degrees.
Draw another rectangle: 80mm. by 4mm. so that one of its ends intersects the bottom of the first rectangle. it should look a bit like this:
Click on View then Zoom in. Zoom in on the corner where both rectangles overlap.
Use the Arc or Fillet tool to join the rectangles with smooth curves:
Snip away the remainder of the rectangles with the scissors tool and click on Line then Toggle Sketch Filled to check that it will extrude.
Extrude the shape to 80mm.
Save your work.
You can now personalise this basic shape to your own design.
