The Earth - MEC

thingiverse

Hi all, I designed this globe for the MEC Challenge as a great way to memorize earth geography, major cities location, and learn latitude/longitude locations. How I Designed This Equator, Arctic and Antarctic lines and Capricorn and Tropic lines are represented on the globe. Google Earth drawing pictures were used as references. Top, rear, right, and left drawing pictures show how the different parts fit together. Continent's contour is defined by the borders between each landmass. The Globe Project Introduction This project aims to improve 3D vision, geography, 3D drawing skills, conception interest, and some engineering skills by studying globe's part assembly. Makers of this project can easily modify scale and located cities, add major mountains, and add typography on the globe. The Globe could be hung (A wire could lock the four parts together?) or placed on a desk with a soft flat bottom. 0° 0' is located near the western African coast and is represented by a small extrusion. Greenwich meridian is represented by a ring. Each 10° latitude are represented by half rings. Equator, Arctic and Antarctic lines and Capricorn and Tropic lines materialized by rings. Cities can be materialized on the globe by moving (copy/move) this body to the desired location: For example: London is at 51° 30' 26" North - 0° 07' 39" West So I copied/rotated the "Zero Point body" to 51.30° UP to the origin. Then, (with a second function) I rotated (no copy) the body to 0.07° LEFT to the origin. This technique easily allows makers to improve their continent's drawing contour. Google Earth's distortion could also be skipped by sketch picture adjustment after cities placements. I'm Still working on it Thanks for your interest.
