PrintLab have a new lesson coming soon that will allow anyone to turn a contour map of their chosen area into a 3D contour model! The lesson is an extension of their first lesson "Make a 3D Contour Model of Mt Everest" and goes through the entire process from calculating distances and scale to tracing contours on CAD and creating a 3D model to be 3D printed.
Check out this example, where PrintLab created a 3D model of Mount Taranaki in New Zealand.
If you'd like the new lesson plan to be sent to you as soon as it's completed, just let them know by emailing hello@weareprintlab.com
