Sine wave function

[Bill Henderson]

Does anyone know how to create a sine wave spline in Solidworks... or at least how to apply the equation?

 

Thanks for any input.

Not sure about Solidworks, but Mastercam can plot a Sine wave (as well as other equations).

 

Try running the 'fplot' chook. There are instructions in the Mastercam Help file on how to use it...

Ok so .. make your sine wave in mastercam save as DXF and import into solidworks..

 

And as for the original question no idea how to do this in solidworks .. kind of doubt there is an easy way without and add on

Have you looked at this:

Here's what one of my Design geeks said, which looks to be along the lines of the post above:

 

 

You can either use the “equation driven curve” sketch tool by clicking on the drop-down menu on the spline button in the sketch window, or write the equation in Excel and import the data points into Solidworks using Insert>>Curve>>Curve Through XYZ Points… Depends on what he’s trying to use it for I guess.

Thank you all. Got it.

Found an easy way if anyone ever needs it.

 

I am currently working with sheet metal.

 

The feature is out in some crazy plane so the spreadsheet driven curve was a pain.

 

Here is what I did.

 

A helix is by all means a sine wave in three dimensions...so I created my circle in the plane I needed tangent to my cut out and exited the sketch.

 

Then I created a helix from that circle with the circumference x PI for my pitch.

 

Picked the plane intersecting my cylinder and projected the helix onto it. Done.

 

Came out perfectly on the unrolled sheet.
