Hi, it seems that most of the THREE.Geometry documentation are wrong.

It says for the PlaneBufferGeometry

> Each of the contructor parameters is accessible as a property of the same name. Any modification of these properties after instantiation does not change the geometry.

But the properties are accessible through the property named **properties**

There is also a typo to the word **constructor**

Have a nice day 🙂

@rroux-gpsw the documentation is created by the community, so if you see an error it would be great if you fixed it. There’s an ‘edit’ button in the top right of each page.

That said, in this case I think it’s just badly worded. As you say, it says:

> Each of the contructor parameters is accessible as a property of the same name

…and yes, you can access each of them via `PlaneBufferGeometry.parameters` property. Also, changing them after instantiation does nothing, so that part _is_ correct.

If you want to rewrite this more clearly, please do!
