Rhino 3D V6 : designing a catapult Level 1

Navigate the Rhino 3D v6 interface and four viewports, learn basic drawing and surfacing tools, and build a simple catapult using snapping and essential commands.

Set up Rhino with imperial inches or millimeters, enable snap, and dock layers and properties for the chassis. Draft accurate geometry by drawing, offsetting, trimming, and extruding to a solid.

Create stand in Rhino by selecting parts, drawing lines at 3 in height and 0.9 in, snapping, offsetting curves, projecting, joining into a closed surface, extruding to 0.25, and mirroring.

Strengthen the catapult arm by adding material, creating a solid through revolve, caps, and boolean operations in Rhino 3D v6, then rotate and align parts into a sturdy union.

Refine the catapult arm by adding cavities and holes for torsion cables and a back hook for the winch, then simulate rotation and refine with sweep and boolean operations.

Design torsion cables for a catapult in Rhino 3D v6 by building 3D curves from points, shaping cross sections with circle around curve, and sweeping them toward rapid prototyping.

Explore adding notches and fillets in Rhino 3D v6, using variable radius fills and precise corner snapping, then apply boolean union and difference to shape the chassis.

Learn to adjust holes and notches in Rhino 3D v6 using solid edit tools and control points, applying tolerances for accurate fits in CNC and rapid prototyping.

Apply textures and materials in Rhino 6, using ground plane, wood and metal textures, and gloss control. Master non-destructive sub-element selection, texture mapping methods, and match mapping for aligned grains.

Create a rope for a catapult in Rhino 3D V6 by modeling a curved path and using match curve, helix, and sweep rail to form a tangential rope around winch.
