The fit spline tool in SOLIDWORKS is a powerful feature that allows users to create smooth and precise curves that accurately represent a desired shape. The fit spline tool is particularly useful for creating organic and complex shapes, such as those found in product design or industrial design.
Step 1: Activate Fit Spline
To use the fit spline tool in SOLIDWORKS, simply select the fit spline command from the spline tool dropdown menu or from the spline tools toolbar. Then, select the points on the sketch where you want the spline to pass through. It is possible to preselect your desired geometry as well before activating the tool. It’s important to choose points that accurately represent the desired shape of the curve, as the fit spline tool will create a curve that passes through these points.
Once you have selected the points, SOLIDWORKS will automatically create a spline that passes through them. You can then adjust the shape of the spline by manipulating the spline handles and control polygons. Spline handles are used to adjust the curvature of the spline at a particular point, while control polygons are used to adjust the overall shape of the spline.
Step 2: Adjust Fit Spline Parameters
One of the key benefits of the tool is that it creates a smooth curve that accurately represents the desired shape. This can be particularly useful when creating parts with complex or organic shapes, as it allows you to create a curve that follows the contours of the design. Additionally, the fit spline tool can be used in conjunction with other sketching tools, such as arcs and lines, to create more complex shapes.
Once activated you can adjust the parameters of the spline through the property manager. Fit splines have the ability to replace existing geometry. Toggling on the delete geometry option will completely remove the original geometry. The closed spline option will create a closed loop regardless of the selected entities. The constrained, unconstrained, and tolerance options are used to compare the converted geometry to the original geometry.
The fit spline tool in SOLIDWORKS is a powerful feature that allows users to create smooth and precise curves that accurately represent a desired shape. Additionally, it’s important to remember that splines can be computationally expensive, so using too many splines or creating overly complex shapes can impact performance. While it can be complex to use, it is a valuable tool for creating organic and complex shapes in product design and industrial design.
