In Onshape, the "Loft" feature is a powerful tool used to create smooth and continuous transitions between two or more cross-sectional profiles. It allows designers to create complex 3D shapes by defining a series of 2D sketches, called sections, and then blending or interpolating between them to form a seamless 3D surface.

To use the Loft feature in Onshape, you select two or more sketches representing different cross-sections. Onshape then generates a lofted surface or solid that smoothly connects these sections, creating a continuous and visually appealing shape. You can control the shape of the loft by adjusting parameters like guides, sections' tangency, and weighting factors.

The Loft feature is beneficial in various design scenarios, such as creating organic shapes, aerodynamic surfaces, and complex geometry found in product designs. It allows for the creation of intricate and visually appealing 3D models, helping designers bring their creative ideas to life with precision and efficiency.


In Onshape, the "Sweep" feature is a powerful tool used to create 3D geometry by sweeping a 2D sketch along a specified path. It allows designers to generate complex shapes and profiles by moving the sketch along a defined trajectory, creating a continuous solid or surface.

To use the Sweep feature in Onshape, you start by creating a 2D sketch that serves as the profile to be swept. Then, you select the sketch and choose a path, which can be a 2D or 3D curve or edge. Onshape then sweeps the sketch along the chosen path, creating the 3D geometry.

The Sweep operation is particularly useful for designing components like cables, piping, and intricate molding profiles, where the cross-sectional shape changes as it follows the specified path. It enables the creation of a variety of shapes with ease, making it a valuable tool for designers and engineers working on complex designs in various industries.
