Here's how to make the pen clip in Pro Desktop


Open a new design in Pro Desktop.

Change the units to Millimeters

Move the Initial sketch to the Frontal workplane


Draw a rectangle that is 44 mm long by 2 mm tall

Use the rectangle sketch to extrude it 4 mm

Show it in isometric (shift i)

Your sketch must be on the Frontal workplane.

The end to the left is going to have the circle parts.

The end to the right is going to have the clippy part.

Select the left side with the Select Faces Tool.

Make a new sketch and workplane. (Control K)

Call the sketch "circles"

Call the workplane top


The new sketch should be the active sketch.

You are going to draw the profile of the circles on the sketch.

Choose View onto Workplane (Shift w)

This will have you looking at the very end of the clip.

Move the mouse over the top line. You should see the attraction point change in size. It should be large at both ends and the center of the line, and smaller in other parts of the line.


Make a vertical line from the center of the top line.

Toggle the line construction by either right clicking on it (or choosing Control g)


Use the construction line as the center of the two circles you need to make.


Make sure your active sketch is Circles sketch on the Top workplane.

The inner circle is 6.5 mm

The outer circle is 8.5 mm


From the top of the block, draw a straight line up from each side. Hold the shift key when you make the line and it will attract to the circle.

Complete the sketch by drawing a straight line from the bottom of the two lines you just made.

Dimension one of the vertical lines 1.5 mm


You should now have a valid sketch (filled) that is the shape of the top of the clip and ready to extrude.

Extrude the sketch.

Add material

Thickness is .5 mm

Below the workplane

View the design in isometric.

Survey all you control.

Make the profile of the clip

Activate the Initial sketch

View "onto workplane" shift w

Use straight lines to make something that looks roughly like the profile of the clip. It should bump up at the end.

Basically, make a triangle at the end and a long thin part that leads to the end with the circles.

Delete the extra segments of the profile. Make sure you get all the crumbs and don't leave any gaps.

Update the document, the new profile should be the extrusion.

Deal with any problems before moving on.

Round the clippy part.

Use the spline tool to round the straight lines of the triangle.

With the spline tool (B key) Click once on the line you want to cause to curve. Then click and hold it, the line should curve. Make it so that both lines curve evenly.

Update the document, deal with any problems before moving on.

Shift I, Shift A

You should see that you have something that looks pretty close to the clip.

Using the Select Faces Tool, select the flat area between the circle end and the clippy end.

Choose Shell solids, use .5 mm as your distance.

The part is designed now.

Print your design in four views, base, frontal, lateral and isometric.

Import any sketch dimensions, add any others you need.
