Hello, I have watched a video on Youtube about using a method for getting the 3D coordinates of a 3D blade. The engineer used a sensor and touched the blades surface by it and it was transferred to solidworks....Any help to know this method?
Thanks
Here are some basic info on 3D scanner:

The best way to capture the geometry info is using a 3D scanner.
Other option is to use a digital camera and the Autodesk ReCap software:

You can use a 3D Scanning arm for accuracy. The brand of arm and scanner depends on the accuracy you need. Kreon (a French brand) can be accurate to 37um. You would be able to obtain a point cloud of the blade profile. I would use Geomagic DesignX to convert the point cloud to a sketch for Solidworks.
Hi. The answers do cover what you can do to get the geometry of the blade into solidworks. The technique is 3D scanning. As discussed, you use a 3D scanned to generate a cloud mesh which is then imported into Geomagic Capture(an add in inside solidworks which you have to pay for). You might have the tools and license at your organisation though.
But, I just wanted to add information about what you shared as well. In the video you saw, the person was probably using a CMM (co ordinate measurement machine). These were very popular back in the day, still are for some purposes. They have a ruby tip. The system is basically calibrated first. Then you have to set your part on the bench..tight. it should not move. Then once in place, you make the ruby tip touch the blade anywhere you want to. You have to select what type of measurement you are doing in the CMM manager. Then basically it's the same thing as making a point cloud of the blade outer dimensions. These are 3d co ordinates which can be imported into a CAD software to make the design off those points. Now, it depends on your purpose. Why do you need the blade geometry?
Point to note- when using the 3d scanner, you get the point cloud, but, you are responsible for making features out of that cloud. At best, solidworks will help you make a sketch by recognising regions. This is not accurate at all times, I have experienced It. There are deviations since you are basically tracing it. With a CMM you will have accurate points that you can use in the geometry.
Once again, depends on your purpose.
