Learn to create and assemble a functional scissor lift mechanism in this 19-minute video tutorial focusing on FreeCAD's new Assembly workbench introduced in version 0.22. Master the process of designing individual components like bases, arms, and pins using the Part Design workbench before exploring how to combine them using various joints and constraints. Discover how to apply revolute and cylindrical joints to simulate realistic movement between parts, organize assemblies effectively, and ground components properly. Follow along with provided FreeCAD files from the GitHub repository as the instructor demonstrates essential assembly concepts crucial for CAD designers working with multiple moving parts. Take on the challenge of implementing constraints to limit pin movement within slots, testing your understanding of FreeCAD's assembly capabilities. Access additional resources through the accompanying written guide, which includes detailed instructions and supplementary materials for both hobbyists and professionals exploring open-source CAD solutions.
