SolidWorks tutorial: Using the LOFT command

The LOFT tool is one the many Solidworks that help you create smooth and organic shapes. It creates a shape by making transitions between multiple profiles and guides curves thus allowing you to create complex geometry with a single tool.

Solidworks LOFT

Let’s take a look at how we can create a model like the one on the picture below using with Loft command.


Step 1

First Create a New Part


Step 2

We need to select the desired plane.

Click on the Top plane and select sketch


Step 3

Make a circle with the origin of the sketch as the origin of the circle and click on smart dimension and give 150 mm for diameter.


Step 4

Click on the Top-Plane, go to features and select Reference/Geometry and select Plane (Features >> Reference Geometry >> Plane)


Step 5

Select the Top-Plane as the first reference and then specify 100 mm in the dimension box.


Step 6

Make another circle with the origin of the sketch as the origin of the circle on a new plane and then click on Smart Dimension and enter 200 mm as its diameter.


Step 7

Click on Plane1 and then go to features and select Reference/Geometry and enter 100 mm as dimension to help create the object on Plane2


Step 8

Then make another circle on plane2 and use Smart Dimension to give 100 mm as diameter.


Step 9

Now, we are going to create a line that will help guide the shape of the 3D object we are trying to end up with. Click on Front Plane and then select Sketch


Step 10

In the next step, use the Spline command and draw lines like shown on the picture below


Step 11

Then Use the Mirror command like shown on the picture below


Step 12

Go to Features, select Lofted Boss/Base and in the Profiles tab select three sketches. The most basic method of controlling the LOFT is affected by where you click when selecting your profiles.

When creating this complex geometry, SolidWorks will attempt to line up the loft profiles based on the entities you choose. You can change the positions of green points to alter the shape of the final object.


Here is one geometry we can end up with using this technique. Feel free to experiment, that will help understand the LOFT command better.


You can also use the guidelines to have additional degrees of control over the geometry’s shape.

This feature is similar to the sweep feature. You can also use a single sketch or various sketches as guidelines for the loft command. Here, we are using two guidelines. To do so, go to Guide Curves and select two guidelines and click on Okay.


This tool is very valuable for organic surface modeling but takes some practice to get accustomed with. You might want to create a totally different object following this tutorial to grasp it a little bit more.
