Assignment 6: Douglas DC-3
Objectives:
Removing Material & Adding Complexity
• Use the shell and the cut operations (extruded, revolved,
swept, and lofted) to remove material from a solid part
• Use mirrored features, linear patterns, and circular
patterns to create a solid part
• Use fillets, chamfers, and 3D text to add detail to a solid
part
• Use geometric and parametric dimensional constraints to
fully define sketches
• Use good techniques to make sketches efficient, dynamic,
and fully defined

Douglas DC-3
• Use shell, cuts,
patterns, mirrors,
edge treatments, and
text to finish the
model of the DC-3
• Use the provided
drawing and images
for reference and
approximate
dimensions
• Use geometric and parametric constraints to ensure all
sketches are fully defined
Required:
• Airplane
• Full airplane (not half airplane)
• Engines
• Three propeller blades
• Engine nacelle (hollow engine)
• Rounded engine inlet
• Hollow inlet air scoop
• swept or lofted cut, extending into
nacelle
• Hollow exhaust pipe
• swept or lofted cut, extending into
nacelle
• make sure not to have any
extraneous leftover pipe segments
• Engine-to-wing smooth radius
• Fuselage
• Fuselage skin
• hollow fuselage only (nosecone,
cockpit, passenger compartment, tail
section) – not wings or
vertical/horizontal stabilizers.
• Average skin thickness on a DC-3 is
0.050’’
• Cockpit windshield
• cut all the way through the fuselage
skin
• Cabin windows
• cut all the way through the fuselage
skin
• Airline name
• has to be an actual solid feature,
correctly formed on both sides of the
airplane
• Wings
• Wing-to-body fairing (variable
radius fillet)
Douglas DC-3 Solid Model Detail
Optional (possible extra credit):
• Other ideas
• Control surfaces
• Passenger entry/exit door
• Baggage compartment door
• Antennas
• Interior details
• Landing gear
Assignment
• Download the following ZIP archive from Canvas to complete the assignment:
• Files (solid model, drawing, images): Section F - Assignment 6 - DC3 Files.zip
• Submit the following files on T-Square:
• Part: Lastname_Firstname_F_6_DC3_part.sldprt
• Drawing: Lastname_Firstname_F_6_DC3_drawing.slddrw
Lastname_Firstname_F_6_DC3_drawing.pdf
• Drawing should contain the 3 standard orthographic views (front, side, top) and
1 pictorial view of the completed airplane
• Also dimension the outer engine nacelle diameter, overall wing span, and overall length in
the drawing file (refer to the sample image on the next slide)
• Notes on submitting the drawing (.slddrw) file
• (!) Make sure to save your drawing as a Detached Drawing [“Save As” - > “Save as type:” ->
“Detached Drawing (*.slddrw)”] before you submit it in Canvas.
• Failure to do so might result in an unreadable file
• NOTE: Only use the “Detached Drawing” option for drawings intended for digital
submission.
• Due – see Canvas
