Build a drone: payload and sliders
The last parts hang under the frame: a camera on its gimbal and the battery in its straps, placed where they belong without any module. Then the sliders show what the graph was built for.
-
The payload hangs under the frame: a camera on its gimbal at the front, and the battery in two straps. Shapes made of a few primitives are nodes: the camera is a box with its edges rounded joined with a cylinder for the barrel, the battery a rounded box, the lens a glass cylinder. The gimbal's bracket is a profile of six points and the straps a pair placed by a loop, so those two are code components.
-
Add typescript editor as gimbal: hidden, with the code below.
-
Add box as camera box: width 24, length 20, height 18, center [0, -26, 55], hidden.
-
Add fillet edges as camera body: radius 3, hidden.
-
Wire camera box › result into camera body › shape.
-
Add cylinder as lens barrel: radius 6.5, height 9, center [0, -26, 63], direction [0, 0, 1], hidden.
-
Add create list as camera parts.
-
Wire camera body › result into camera parts › listElements.
-
Wire lens barrel › result into camera parts › listElements.
-
Add union as camera: hidden.
-
Wire camera parts › list into camera › shapes.
-
Add cylinder as lens: radius 5.2, height 1.5, center [0, -26, 71.5], direction [0, 0, 1], hidden.
-
Add box as battery box: width 36, length 72, height 26, center [0, -16, -20], hidden.
-
Add fillet edges as battery: radius 3, hidden.
-
Wire battery box › result into battery › shape.
-
Add typescript editor as straps: hidden, with the code below.
-
Wire gimbal › result into aluminium › entity.
-
Wire camera › result into polymer › entity.
-
Wire battery › result into polymer › entity.
-
Wire straps › result into accent › entity.
-
Add pbr metallic roughness as glass material: name glass, base color #0c1522, metallic 0.1, roughness 0.05, z offset 2, in the Materials group.
-
Add options occt shape as glass look: precision 0.05, draw two sided off, edge colour #f2f2f2, edge width 4, in the Materials group.
-
Wire glass material › result into glass look › faceMaterial.
-
Add draw any async as glass in the Materials group.
-
Wire glass look › result into glass › options.
-
Wire lens › result into glass › entity.

Press Add a comment, double-click the comment and write:
Payload
A camera on a gimbal at the front and the battery in two straps underneath, placed directly without modules.
-
Select the comment, gimbal, camera box, camera body, lens barrel, camera parts, camera, lens, battery box, battery and straps, press Group selected components and title the group Payload.

Move the sliders: six arms rebuild the drone, every Around follows the arms slider, and the propeller shrinks to fit between its neighbours.
- On arms, number 6.
