There seems to be some problem with the drawing of the polygons

I used the same array of points to draw a line and a polygon, and the polygons didn’t look quite right.How to fix this…

Hi @Aoi, your Sandcastle looks like another example of this open issue:

Until that is resolved, one option is to split your polygon into smaller pieces. Here is an updated Sandcastle with the polygon in 2 pieces.

Thank You :grinning:
