Date: 2020-09-30

Part 1 of 3 discussing the second phase of the Fusion 360 Marble Run exercise by continuing the sample design. Please note that several mistakes are included which are fixed later in the process. Some time points in the video:

01:18 creating the foot component
01:28 using isolate to hide parts
02:45 using a long click to select hidden features
04:00 adding slots for tabs
07:13 creating the central vertical strut
07:40 using a midline sketch plane for a symmetrically extruded part
08:38 roughly drawing the contour
09:30 adding constraints to locate the contour
11:25 associatively locating the tabs using projected geometry
12:10 dimensioning a press-fit wedge tab in laser-cut plywood
13:23 drawing parts with deliberate overlap to represent press-fits
14:12 jump cut after detailing three more tabs
15:04 extruding strut symmetrically around drawing plane
15:55 beginning the side barrier part
16:15 creating the sketch plane, somewhat incorrectly (later replaced)
16:44 creating the barrier component
18:44 drawing the contour with lines and arcs
20:09 projecting the tab center lines, at which point I fail to notice a perpendicularity problem (later fixed)
22:55 extruding the barrier part
23:32 considering the need for a cross-brace, but postponing creation
24:40 adding a section view
25:19 tab section view, at which point I fail to notice an parallelism inconsistency (later fixed)
27:05 recap and summary
27:41 demonstration of associative changes as parameters are changed
