Home » How to use SolidWorks Lofted Boss?

In SolidWorks, we have many features which we use more often, and one such feature is the lofted boss. It’s a very common feature present in almost all CAD software. It is slightly different from the extruded boss and Sweep boss feature. It is mostly used to make more interplane geometries. Unlike extrude, revolve, and sweep, loft uses two or more sketches to complete the operation. This feature’s particular property helps us make more complex geometries. The loft feature is also present in surface design.

There are mainly two ways to use this feature and they are as follows:

  • Using Profiles
  • Using guided curves.

We shall be looking into each way closely.

In this article, we will learn to make airplane wings using the loft feature. The steps to be followed are as follows:

  1.  We need to make a sketch first by importing the curve of the airfoil. Here we have imported NACA2415 airfoil.
  2. Now make a reference plane to make another sketch. Since we need to make a taper wing we need 3 planes and 3 different sketches.
  3. Once the sketches are made select the loft base option.
  4. Choose all 3 sketches as a profile.
  5. Here we can modify the shape based on the position of green pointer.

Now let us use the guided curve method.  Start with a 3d Sketch to make a guided curve.

Now simply select the guided curve along with the 2 sketch profiles. The two profile should be the boundary sketches.

Above are the steps to use loft base in SolidWorks.
