FreeCAD for Mechanical Engineers : Technical 2D Drawing

Master the sketcher workbench basics by using the documentation to define geometry and constraints, create and edit sketches on the x y plane, and customize toolbars.

Learn how to reorient a sketch and transfer it between planes in FreeCAD, then use sketcher geometries to create points, lines, arcs, and circles with constraints.

Explore sketcher conic sections in FreeCAD by creating ellipses, parabolas, hyperbolas, and ellipse by center or three points, using construction geometry and baseline.

Use construction mode in FreeCAD to turn lines into construction lines for precise constraints, enabling distance and angle between centers. Ensure sketches are closed to enable extrusion for 3D objects.

Learn how to apply dimensional constraints in FreeCAD's sketcher to fully constrain a 2d drawing, using origin references, lengths, distances, angles, construction lines, and parallelism.

Apply FreeCAD sketching techniques to build a multi-circle mechanism, using construction geometry, tangent circles, arcs, and constraints while exploring degrees of freedom, polar patterns, and trimming challenges.

Build a fully defined FreeCAD 2D sketch by arranging symmetric circles with precise diameters, setting center distances and angles, and applying tangency and parallel constraints.

Construct a symmetric 2D sketch in FreeCAD for exercise six, placing a central rectangle, equal diameter holes, arcs, and tangent constraints, while using dimension control and y-axis symmetry.

Practice creating a precise 2d sketch in freecad for mechanical engineers by applying trimming, constraints, parallel and equal lines, arcs and circles, and defining distances and diameters.

Develop a 2D FreeCAD sketch by building a central circle and two tangent circles, converting arcs, and applying tangency, mirroring about the origin, and symmetry constraints.

Practice exercise nine builds a circle with slots and tangencies, using construction lines, symmetry, trimming, and constraints; it covers mirror issues and managing degrees of freedom for 2D drawing.

In this Ex10 exercise, learn to build a smiley-like sketch with tangents, circles, and arcs in FreeCAD, define centers, radii, and tangency constraints, and finalize the outer frame.
