I changing marker\_line\_width value. There is no effect.

```auto
x = np.arange(10)
y = np.arange(10)
z = np.arange(10)
go.Figure(go.Scatter3d(x=x, y=y, z=z, mode='markers', marker_line_width=1000))

```

version=4.5.4  
using jupyter notebook

Hi @unfinity,

You have to tell plotly to draw the line and also remove `marker` in the `line_width` parameter, see below.

```auto
import numpy as np
import plotly.graph_objects as go

x = np.arange(10)
y = np.arange(10)
z = np.arange(10)
go.Figure(go.Scatter3d(x=x, y=y, z=z, mode='markers+lines', line_width=1000))

maybe don`t use `1000`as line width now ^^

Alex-
```

Thanks for reply! But I wanted to increase the border width of markers, that is, to make them more thicker and eye-catching. Like this:

As far as I checked, you can only set the line width to zero or positive non-zero. Any positive non-zero value ends up showing the same width.  
Maybe it is a bug or not a feature.
