How Do I Project a Surface in SolidWorks?

Are you looking to project a surface in SolidWorks? This powerful software allows you to create accurate 3D models and simulate real-world conditions. In this tutorial, I will guide you through the steps of projecting a surface in SolidWorks using various techniques.

Using the Projected Curve Feature

The Projected Curve feature in SolidWorks allows you to project the outline of a face or surface onto another face or surface. This can be particularly useful when you need to create complex geometry or when you want to transfer the shape of one surface onto another.

Step 1: Selecting the Faces

To start, open your SolidWorks model and navigate to the top menu. Click on ‘Insert’ and select ‘Curve’ from the dropdown menu. Then, choose ‘Projected Curve’ from the submenu.

A dialog box will appear, prompting you to select the faces that you want to project. Use your mouse to select the desired faces by clicking on them. You can select multiple faces by holding down the Ctrl key while clicking.

Step 2: Adjusting Projection Settings

After selecting the faces, click on ‘Next’ in the dialog box. Here, you can adjust various settings related to the projection.

  • Projection Type: Choose between ‘Normal To Surface’ or ‘Along Vector.’ The former projects perpendicular to the selected face(s), while the latter allows projection along a specified direction.
  • Projection Direction: If you chose ‘Along Vector,’ enter a vector direction for projection.
  • Tangent Edge Length: Define a length for tangency control along edges.
  • Simplify Results: Enable this option if you want SolidWorks to simplify the projected curves.

Once you have adjusted the settings, click on ‘Next’ to proceed.

Step 3: Defining Projection Parameters

In this step, you need to define additional parameters for the projection. These parameters include:

  • Projection Distance: Specify the distance by which you want to project the curves.
  • Curve Type: Choose between ‘Intersection Curve’ or ‘Split Line.’ The former creates a single curve at the intersection of projected faces, while the latter splits the selected face(s) into separate regions.
  • Ruled Surface: Enable this option if you want to create ruled surfaces between projected curves.

After setting these parameters, click on ‘Finish’ to complete the projection process.

Alternative Method: Using Sketch Tools

If you prefer a more manual approach, SolidWorks also offers sketch tools that allow you to project a surface onto a sketch plane. Here’s how you can do it:

Step 1: Creating a Sketch Plane

In your SolidWorks model, go to ‘Insert’ in the top menu and select ‘Reference Geometry.’ From there, choose ‘Plane.’

A dialog box will appear, prompting you to select references for creating a new plane. Select an existing face or surface that you want to project onto.

Step 2: Projecting onto Sketch Plane

Create a new sketch on the newly created plane by clicking on ‘Sketch’ in the top menu and selecting ‘New Sketch.’

In the sketching environment, go to ‘Tools’ in the top menu and choose ‘Sketch Tools.’ From there, select ‘Convert Entities.’

A dialog box will appear, showing you all the available faces and surfaces for projection. Select the desired surface by clicking on it, and click on ‘OK’ to project it onto the sketch plane.

You can now use the projected surface as a reference to create new sketch entities or perform further operations in your SolidWorks model.


Projecting a surface in SolidWorks is a powerful technique that allows you to transfer the shape of one face onto another. Whether you choose to use the Projected Curve feature or the sketch tools, both methods offer flexibility in creating complex geometry and enhancing your 3D models.

Remember to experiment with different settings and techniques to achieve the desired projection results. With practice, you will become proficient in projecting surfaces and harnessing the full potential of SolidWorks for your design projects.
