Picture of Making Turbine blades on solid works
In the .instructables i will show you how to make the turbine blades for a wind turbine on solid works 
the skills from the .instructable can be used for making many different things on Solid Works.

Step 1: Step 1 - outline

Open a new part on Solid Works. To achieve an accurate outline shape of a turbine blade a good cheat is to import a profile drawing of one into the Solid Works sketch then sketch over it tracing its curves using splines and lines.

Use the image attached or another image or the desired blade.
Resize the image to the size of blade yo want

To make it easier to draw round the shape of the blade it is a good idea to split it into 6 sections using the linear sketch pattern.

Where the vertical lines cross the outline of the blade insert sketch points.

You can then delete the lines leaving only the sketch points

Using the spline tool you can draw round the outline of the shape
Use the arrows to adjust the lines to fit the outline of the picture
once you have done this you can delete the picture leaving only the outline

Step 2: Step 2 - New drawing planes

Using the sketch points as reference add a new drawing plane. To add a new drawing plane go to “reference geometry” and click “plane” then select the plane that is at a cross section across the blade
