I am trying to initialize an empty GeometryBasics.Point{2, Float32}, could anyone help?

What would a point without coordinates look like? How do you want to use it?

I think is just ` point = Point2f0[]` .

You can’t initialize an empty point, but you can initialize an empty array of points, which is what @lazarusA suggested.

Note that with the latest version it’s now `Point2f[]`.

thank you!
is there document of Point2f function? was trying to search but didn’t find it…

Note that that is a syntax sugar for
```julia
GeometryBasics.Point{2, Float32}[]
```
It is not something different. Maybe that was not clear.

GeometryBasics is still underdocumented unfortunately. As pointed by @lmiq `Point2f` is an alias for `Point{2, Float32}`. You can see this easily in the REPL:
```julia
julia> Point2f
Point{2, Float32}
```
Typing `?Point2f` or `?Point` shows the help:
```julia
help?> Point2f
search: Point2f Point2 Pointf Point4f Point3f Point1f Point4 Point3 Point1 Point pointer PointMeta pointmeta PointWithUV
No documentation found.
Summary
≡≡≡≡≡≡≡≡≡
struct Point{S, T}
...
```
So although there is no documentation written for `Point`, we can see it’s the name of a struct type. The type name can be used as a function to instantiate the type, it’s called a constructor (see the manual [here](https://docs.julialang.org/en/v1/manual/constructors/)). But when you write `Point2f[]` you don’t use `Point2f` as a function (constructor), but simply as a type name, just like we write `Int[]` to declare an empty array of `Int`.
