 +
Step 8: Right Click the ‘Blue Circle’ (see screenshot) on the object and select ‘normal to’ and again select  ‘new sketch’ option after.

 +
 +
Step 10: Nest, use the line tool to draw a rectangle as shown in the picture. Make sure the ends of the top line are on the circle, and that the line is horizontal.

Step 12: Click on the Features tab and select the ‘Extruded Cut’ option. under "direction 1", select "up to surface" for the depth of the cut. Select the pink face as the surface.
 +
 +
[[Image:Quena_12.png|400px]]
 +
 +
Step 13: Next, create a new sketch on that pink face. on this face, draw 2 lines vertically down from the sides of the notch, and then connect them with 2 arcs. The arc tool is circled in red in the upper left corner.
 +
Dimension the arcs as shown.
 +
 +
[[Image:Quena_13.png|400px]]
 +
 +
Step 14: Next, use the trim tool from earlier to reduce the sketch down to a single loop.
 +
For the upper parts of the 2 vertical lines, trim them to construction geometry. This preserves the relation between the lines and the notch.
 +
For the lower part of the lines, uncheck the "keep trimmed entities as construction geometry" box, and it will delete the overhanging part of the line.
 +
 +
[[Image:Quena_14.png|400px]]

In this TV, we will be creating a quena.

Bill of Materials

  • 1/2" PVC
  • 3D printed parts

CAD

Step 1: Open SolidWorks 2020, and select a new part. Don't forget to save your file frequently as you go. In the bottom-right corner of your Solidworks window, change the units from IPS to MMGS (milimeter, gram, second)

Step 2: Select the Front Plane in the design tree (the left column on your screen) to begin your sketch. Click on the Sketch tab above and click Sketch.

Quena 1.png

Step 3: Draw out the shape below. Start the lower left corner on the origin (the red arrows), and make sure the lines snap to horizontal and vertical. Using the smart dimension tool, which you can get either on the menu at top, or by holding your right mouse button and dragging up. If done correctly, the entire sketch should be black, indicating that it is fully defined.

Step 4: In the top left corner, click Exit Sketch (your sketch should turn light grey). Click on the Features tab and select the Revolved Boss/Base option. Click on the "axis of revolution" box, and select the bottom line. The preview should match the picture below.

Click the green checkmark in the left column if everything looks good.

Step 5: Select the Front Plane in the design tree (the left column on your screen) to begin a new sketch. Click on the Sketch tab above and click Sketch.

Step 6: On the new sketch, select the ‘Ellipse’ option to draw the same shape as the screenshot. Place the corner of the eclipse on the corner of the object, and add dimensions to constrain it.

Step 7: Click on the Features tab and select the ‘Extruded Cut’ option. Select ‘Through All- Both’. Click the green checkmark in the left column if everything looks good like the screenshot.

Step 8: Right Click the ‘Blue Circle’ (see screenshot) on the object and select ‘normal to’ and again select ‘new sketch’ option after.

Step 8: Select the round end face, and create a new sketch. To make that sketch become parallel to the screen, press space, and click on the appropriate face of the cube.

Next, select the "trim entities" tool on the top bar. Select "trim to closest", and make sure "keep trimmed entities as construction geometry" is checked.

Trim the 2 inside lines, so that the solid lines form 1 loop.

Step 12: Click on the Features tab and select the ‘Extruded Cut’ option. under "direction 1", select "up to surface" for the depth of the cut. Select the pink face as the surface.

Quena 12.png

Step 13: Next, create a new sketch on that pink face. on this face, draw 2 lines vertically down from the sides of the notch, and then connect them with 2 arcs. The arc tool is circled in red in the upper left corner. Dimension the arcs as shown.

Quena 13.png

Step 14: Next, use the trim tool from earlier to reduce the sketch down to a single loop. For the upper parts of the 2 vertical lines, trim them to construction geometry. This preserves the relation between the lines and the notch. For the lower part of the lines, uncheck the "keep trimmed entities as construction geometry" box, and it will delete the overhanging part of the line.

Step 15: Now, extrude cut with this sketch. the cut should go all the way through

And you're done!
