You can change the coordinates of points as long as you don't change the topology of the arrangement.
Scaling does not change the topology. You need to scale all points by traversing them one at a time.
Naturally, an intermediate state might be invalid.

Hello,

is there any way to apply a global transformation to an arrangment (i.e.
scaling or translation)?

I tried to modify the point-references of the arrangements vertices (Point2&
point()), and it works somehow, but finally invalidates (?) the mesh. I
guess, this reference should not be used for modification of the underlying
point coordinates.

At least, I need a scaling of the point coordinates. Any idea?

Thank you
