How Do You Curve in SolidWorks?

In SolidWorks, there are several ways to create curves that can be used for various purposes such as creating complex shapes or defining paths for motion. In this tutorial, we will explore different methods to curve in SolidWorks and understand their applications.

Sketching Curves

Sketching curves is one of the fundamental methods to create curves in SolidWorks. To start, you need to activate the Sketch mode by selecting a plane or a surface on which you want to sketch the curve. Once in the Sketch mode, you can use various sketching tools like lines, arcs, splines, and ellipses to draw the desired curve.

When sketching curves, it’s essential to pay attention to control points and constraints. Control points allow you to manipulate the shape of the curve by modifying their positions. Constraints help ensure that the curve remains aligned or tangent to other geometry in your design.

Note: It’s important to keep in mind that sketching curves is limited to 2D space and may not provide the desired results for complex 3D shapes.

3D Sketching

If you need more control over your curves or want to create 3D shapes directly, using 3D sketching is a powerful option. To start a 3D sketch, select the “3D Sketch” option from the “Sketch” menu.

In a 3D sketch, you can create curves by using multiple planes or surfaces as references. You can also add dimensions and relations between different elements of your sketch to define precise relationships between them.

Spline Curves

Spline curves are smooth and continuous curves that can be used for creating organic shapes or complex geometries. SolidWorks provides several types of spline tools:

  • Style Spline: This tool allows you to create a free-form curve by specifying control points and tangents.
  • B-Spline: B-Splines are mathematical curves that pass through control points. They provide more control over the shape than Style Splines.
  • Composite Curve: Composite curves are created by combining multiple entities like lines, arcs, and splines. They can be useful for creating complex shapes.

Spline curves can be modified by adjusting the position of control points or manipulating tangents. Additionally, you can add constraints to spline curves to ensure specific relationships with other geometry in your design.

Wrap Curves

The Wrap feature in SolidWorks allows you to project a 2D sketch onto a non-planar surface or face. By using the Wrap feature, you can create curves that follow the contours of complex surfaces.

To create a wrap curve, start by activating the Wrap feature from the “Features” menu. Select the desired sketch and Target surface or face. SolidWorks will then project the sketch onto the selected surface, creating a curve that matches its shape.


In SolidWorks, there are multiple ways to create curves depending on your design requirements. Sketching curves provides a simple and intuitive method for creating basic shapes, while 3D sketching allows for more control over complex geometries. Spline curves offer smooth and continuous shapes, whereas wrap curves enable you to project sketches onto non-planar surfaces.

By utilizing these various methods, you can effectively incorporate curves into your SolidWorks designs and bring your ideas to life with precision and creativity.
