1. Watch the videos
Dassault Systèmes videos hosted on MySolidWorks: they open in a new tab and a free account is enough. Watch them in order.
Basic SplinesCreate and edit splines with points, handles and the control polygon.↗ Projected CurvesProject one sketch onto another to get a 3D curve.↗ Intersection CurvesCapture the intersection between faces and planes as a sketch.↗ Curve Through XYZ PointsCreate a curve from typed or imported coordinates.↗ Equation Driven CurvesCreate a 2D or 3D curve defined by an equation.↗ Curvature: Analyze and Assess the Quality of Curves and SurfacesAssess the quality of curves and surfaces with curvature combs.↗
2. Key takeaways
A spline is driven by few points: the more points, the more the curve wiggles.
A projected curve combines two 2D views into a 3D curve, ideal as a sweep path.
A curve through points imports coordinates from a text file: handy for a cam or blade profile.
The curvature comb reveals breaks the eye cannot see: check it before any surfacing work.
Tip
For a profile defined by measurements (cam, blade, contour), import the points from a text file: editing the file is enough to update the shape.
