Bram's Sphere Generator This script generates an LDraw .ldr or .mpd file of the shape of a LEGO® sphere constructed of six identical panels of plates around a Studs-Not-On-Top core. For example, choosing a diameter of 6.6-6.8 studs with the "Jumpers" option turned on will create a sphere like Bruce Lowell's.



Diameter: Enter the desired diameter for the completed sphere.

Options

On Off

Jumpers:



Turn on this option to use jumper tiles (1×2 Plate with Center Stud) to smooth the shape.

Colors:



Turn on this option to add alternating bands of color to the sphere to improve contrast between layers.

Studs:



Turn off this option to see what the sphere would look like built with tiles instead of plates.

Sphere:



Turn off this option to see how a single panel (of the six which make up the sphere) is shaped.

Advanced Options

Small Large

Core size:



Some sphere diameters can be built with two different size cubic cores (for example, 3×3×3 studs or 4×4×4 studs), one of which may look better than the other. Choose whether to use the smaller or larger core.

Plate height: This option specifies where in the height of the plate to measure the distance to the desired spherical surface. A height of 0 corresponds to the bottom of the plate, while 1.5 corresponds to the tops of the studs. Choose 0.5 to discount the stud height for a tiled sphere.
