Select the end face or edge and use convert entities to create the sketch for the helix.

How to create knurling!Īfter creating the Extruded rod, start a sketch on the end face or plane. Lets finish by take a look at a conventional helix’s and a common request seen on the SOLIDWORKS Forum. This simple surfacing technique is a handy trick for creating path’s on many a irregular face. A 3D sketch tangent to the helix gives the direction for a cut extrude to taper the cut to the surface. This leaves the the spiral cut with a square ends. Once more create the sketch on the required plane to provide the profile to use with a Cut Sweep. I used the Trim Surface method using the face as the Trim tool. The Swept Surface is created as before by a horizontal sketch as the profile, with the Helix once more as the Path. Once more I used the Height and Revolutions to define the created Helix. The circle again is dimension to fit inside the smallest radius of the revolved shape. The Helix is created via the normal method of a sketching a circle on the created plane. With this model we can start with a simple sketch and use the Revolve Boss to create this shaped.Ĭreating a plane at the require height in which to position the Helix for the spiral cut. This technique is not restricted to only geometric profiles. Hide the Swept Surface and as simple as that, you have a non-circular helix swept part !īy using these Surface features it is a simple process to be able to create the non-circular profile. Using the Swept Boss, select the sketch as the profile and the outer edge of the Swept Surface (Open Group) You will see some people create a 3D Sketch by selecting the outer edge of the Swept Surface, then Convert Entities but this is an unnecessary step. In this case a couple of circles for the profile of the tube. Create a sketch of the required profile to be swept along the created non-circular Helix. Once the Swept Surface is trimmed the Extrude Surface is no longer required and can be hidden. Select the Surface Trim feature and use the Extruded Surface as the Trim Tool, select the Swept Surface (outside of the Extruded Surface) as the section to be removed. Ensure that the profile of the sweep fully extends outside of the Extruded Surface. Use the Swept Surface with the line as the profile and the Helix as the Path. This sketch is a horizontal line from the start point of the helix that extend out past the created Extrude Surface. Your design would determine this from model to model.Ĭreate a sketch on the Plane which intersects the start point of the Helix. For this design I set the start angle to one of the main planes. I tend to use Height and Revolutions but it matters little to how the Helix is defined. In this case to the height if the Extrude Surface. This should be kept inside the shape of the profile sketch. On the same plane as the profile sketch, sketch a circle for the diameter of the Helix. Extrude Surface the sketch to the required height. In this case a square with filleted corners. Start with a sketch of the finished shape of the non-circular helix profile. Lets take a detailed look at how to create the above non-circular helix! So an Extrude acts the same regardless of if you are using a Feature or a Surface. The basic features of Surface tools work in similar ways as Solid modeling. For those who have not used Surface tools, this will be a good introduction, to the use of a few of the basic Surfacing features.

Like all things in SOLIDWORKS there would be a few different ways to create this style of component. What is the point of having a Swept Cut feature if you are not going to cut some threads with it? Again, it is a straight forward creation of the Helix and the profile to be Swept along it.īut what if you require a non-circular helix? Maybe a better description maybe a non-continuous curved helix! By definition I think it still qualities! “tangent line at any point makes a constant angle” What if you require something like this? Let’s be honest, what’s not to like about springs!īefore the Thread feature was introduced in SOLIDWORKS 2016, most, I suggest, once they have conquered the spring would have moved onto creating threads.

You have worked out the basics of the Swept Boss feature and have discover the Helix tool, slightly hidden under Curves.Ĭreate the Helix, sketch a circle and Sweep it along the Helix.

I would take a good guess that the first thing that many model after they have learned basic modeling in SOLIDWORKS would be a spring!
