Fusion Sketch Practice — Object Bank
A reusable list of 2D sketch objects to practice with in Fusion. Pick whatever category interests you and work at whichever tier matches how comfortable you are. All of these are 2D sketch only — no extrude yet; that comes later in the unit.
See Fusion Training for video walkthroughs of the tools these objects use, and Fusion in This Class for access, files, and units. Not sure which tool fits a given object? Check the Fusion Sketch Tools quick reference.
How to use this
- Every object has a version at all three tiers, so you can move up in complexity on the same object instead of switching to something unrelated — start a robot head at Floor Tier and keep adding to that exact sketch as you get more comfortable, rather than starting over on a different shape.
- Floor Tier is a closed profile with 3+ connected lines, 2+ dimensional constraints, and 1+ geometric constraint — start here if you're still building basic fluency.
- Stretch Tier 1 adds one new mechanic — usually tangent arcs, a cutout, or an equal/symmetric constraint — try this once the Floor Tier version feels comfortable.
- Stretch Tier 2 combines several mechanics (nested cutouts, repeated or patterned features, symmetry across a centerline) — reach for this if you're moving fast and want a real design problem instead of more of the same.
- Categories are deliberately mixed (sports, gaming, vehicles, architecture, music, everyday objects) — pick whatever interests you, there's no requirement to work through them in order.
Object Bank
| Object | Category | Floor Tier | Stretch Tier 1 | Stretch Tier 2 |
|---|---|---|---|---|
| House side | Architecture | Walls + triangular roof, no cutouts — closed profile combining a rectangle and a triangle, one parallel/perpendicular constraint | + one door cutout and one window cutout — nested closed profiles inside a closed profile | + two or more evenly-spaced windows — nested cutouts, equal-spacing between repeated features, likely a symmetry constraint across the door |
| Car side profile | Vehicles | Boxy silhouette — rectangle body with two circle wheels, no wheel-well cutouts yet — closed profile plus circle placement | + two tangent wheel-well arcs cut into the body — arc-tangent-to-line constraints | + one door line and one window cutout, tangent wheel wells — combines tangent arcs with a nested cutout, a genuinely hard sketch |
| Skateboard deck | Sports | Elongated rounded rectangle outline — basic closed profile, length/width dimensions | + truck-mounting holes (small circles) — circle placement with dimensional constraints from an edge, repeated similar features | + tangent-arc kicktails at both ends and a patterned cutout graphic/logo shape — tangent arcs plus a nested cutout and repeated features |
| Phone / tablet | Tech | Rounded rectangle outline — rectangle + fillet-style corners, dimensional constraints on both sides | Phone case with one camera-cutout circle — circle-in-a-closed-profile cutout, positioned with two dimension constraints | + a patterned multi-camera cluster and a charging-port cutout — repeated circle pattern plus a second nested cutout |
| Guitar | Music | Guitar pick (rounded triangle) — closed profile with a mix of lines, one symmetry or equal constraint | Simplified guitar body outline, single tangent-arc curve, no waist — one tangent arc transition, a step toward the full body shape | Full guitar body outline (tangent-arc "figure 8" curve) with a sound-hole circle — multiple tangent arcs in sequence, plus a positioned cutout circle |
| Shield | Gaming | Flat top, pointed bottom — closed profile with angled lines, symmetry constraint down the centerline | + a crest/emblem cutout in the center — nested closed profile inside the shield | + a patterned ring of rivets around the edge, plus the crest cutout — circular pattern combined with a nested cutout |
| Stop sign | Everyday objects | Regular octagon — equal-length-side constraint across multiple edges | + lettering across the face (sketch text or simple line-built letters) — introduces the text/sketch-letter tool alongside the equal-side octagon | + lettering plus a patterned ring of mounting-pole bolt holes — text tool combined with a circular pattern |
| Envelope | Everyday objects | Rectangle + triangular flap — same shape family as the house, good for a theme change without new mechanics | + a windowed address cutout (rounded rectangle) — nested cutout plus a fillet | + a patterned row of stamps in the corner — repeated equal-sized rectangles, an early pattern exercise |
| Basketball backboard | Sports | Rectangle with one small notch — introduces a single simple cutout/notch as a coincident-point exercise | + a ring of mounting screw holes around the edge — circular pattern of small circles | + screw-hole pattern, a camera-mount cutout on top, and a nested shooter's-square outline — pattern, nested cutout, and a second nested profile combined |
| Robot head | Gaming/Tech | Rectangle head outline, no eye cutouts yet — basic closed profile | Rectangle with two circular "eye" cutouts — symmetry constraint across a centerline, applied to two separate circles | + an antenna (tangent arc) on top and a patterned mouth-grille of rectangle slats — tangent arc plus a rectangular pattern, on top of the existing symmetric eyes |
| Picture frame | Everyday objects | Single rectangle outline, no mat opening yet — basic closed profile with dimensions | Two nested rectangles (frame + mat opening) — offset/parallel nested profiles | + a patterned decorative border (small evenly-spaced notches) and filleted inner mat corners — pattern plus fillet added to the existing nested profile |
| Home plate | Sports | Simple rectangle placeholder, no angled point yet — basic closed profile, straightforward dimensions | Pentagon with specific angles — angle dimensional constraints, not just length | + a pair of batter's-box rectangles placed symmetrically on either side — symmetry constraint applied across the centerline to a second shape |
| Skate ramp / quarter-pipe | Sports | Straight ramp outline, two straight lines only, no arc yet — basic angled closed profile | Line into a tangent arc — single tangent arc-to-line transition, the core skill for any curved surface | + a second tangent arc back to flat (a full S-curve) plus a thin coping-rail cutout along the top edge — multiple tangent arcs plus a nested cutout |
| Castle turret | Architecture/Gaming | Simple rectangular tower outline, no crenellations yet — basic closed profile | + a few individually-placed notches along the top edge, not yet patterned — introduces the notch shape before patterning | Evenly-spaced crenellations along the top — equal + collinear constraints applied to a repeated pattern of notches |
| Game controller | Gaming | Simple rounded rectangle body outline, no buttons yet — basic closed profile with fillet corners | + one joystick circle and a single D-pad cross shape — introduces a circle and a compound line shape before symmetry is applied | Rounded body, two joystick circles, a D-pad cross, symmetric button circles — symmetry constraint across a centerline applied to several feature types at once |
| Window with mullions | Architecture | Single windowpane outline, no mullions yet — basic rectangle profile | + one mullion crossbar (a single divider), not yet a full grid — one nested divider before patterning | A grid of small rectangle cutouts — repeated equal-spacing constraint practice, a real test of "fully constrained" |
| Box-end wrench | Tools/Vehicles | Simple rectangular shaft outline, no hex cutouts yet — basic closed profile with length/width | + one hexagonal cutout at a single end (Polygon tool) — introduces the polygon tool before both ends are added | Hexagonal cutout at each end, tangent arcs on the shaft — hexagon (equal-side + equal-angle) plus tangent arcs in one sketch |
| Rocket / spaceship | Gaming/Sci-fi | Simple triangular nose body outline, straight-sided, no tangent arc yet — basic closed profile | + a tangent-arc nose cone replacing the straight point — introduces the tangent arc before fins and cutouts are added | Tangent nose-cone arc, fin cutouts, one window circle — tangent arc at the nose, plus symmetric fin shapes off a centerline |
Tips
- Tangent arcs show up the most across Stretch Tier 1 and 2 (wheel wells, ramps, guitar bodies, rocket nose cones) — it's worth getting comfortable with them since they come up constantly.
- Nested cutouts (a closed profile inside a closed profile) are the second most common mechanic — houses, picture frames, phone cases, windows — and preview work you'll do later in the course when you design a CNC-cut project — where the clearance between the two profiles stops being cosmetic and starts deciding whether parts fit. See Tolerance and Fit.
- Patterns (Rectangular/Circular Pattern) show up a lot at Stretch Tier 2 — screw holes, rivets, stamps, mullions, crenellations. A clean repeated feature is one of the clearest signs your sketch is actually fully constrained, not just "looks right by luck."
