Teaching Tech via YouTube

Overview

Save Big on Coursera Plus. 7,000+ courses at $160 off. Limited Time Only!
Dive into an in-depth tutorial on sketch constraints for 3D design and 3D printing. Learn to design a mainboard adaptor mount using dimensioned diagrams and build a frame around it. Master various constraints including equal, horizontal, vertical, tangent, normal, concentric, coincident, midpoint, symmetry, parallel, pierce, and perpendicular. Explore the use of construction lines, the mirror tool, and how to handle over-constrained geometry. Perfect for those looking to enhance their 3D CAD skills using free software like Onshape, this comprehensive guide covers everything from basic sketching to advanced constraint techniques, preparing you to tackle more complex designs in future projects.
