SOLIDWORKS Creating a Helix

Tuesday July 30, 2013 at 9:24am
 
SOLIDWORKS - Creating a Helix/Spiral
 
The Helix and Spiral tool can be cleverly used to generate 3D curves which can be then used as a sweep path. Ideal for creating springs!
The tool will create your desired helix or spiral based on an initial circle sketch and definition values e.g. Pitch and Number of revolutions. 
 
To begin, sketch a circle of the desired initial diameter of the first revolution. Select this sketch and click: Insert > Curve > Helix/Spiral 
 
 
 
 
Now select from the drop-down menu “Pitch and revolution”. This allows you to customise these two variables in the helix and the rest of the data will be calculated for you. Similarly you can define the helix by its height and pitch or height and revolutions depending on which values you know. 
 
 
If you wish to obtain a variable pitch you can select this option. A table will now appear and you can now add in your desired values. Choose the starting angle as well as the preferred direction and click OK.
 
    
 
Have a go!
