Dynamo version

2.16.1.2727

Operating system

Windows 10

What did you do?

Tried to create a simple polygon by points (see attached picture).

What did you expect to see?

A polygon

What did you see instead?

I got a Failed to construct a Polygon from the input points: ACIS_EXCEPTION_FLT_OVERFLOW – Floating point overflow Note that the same issue appears when writing a simple code block, for example this:

point1=Point.ByCoordinates(0,0,0); point2=Point.ByCoordinates(0,10,0); point3=Point.ByCoordinates(10,10,0); point4=Point.ByCoordinates(10,0,0); t1=[point1, point2, point3, point4]; polygon1=Polygon.ByPoints(t1);

....gets the same failure message.

Note also that:

• other curves are created without problems (including Regular Polygons)
• when using older version 2.6.2.15705 there is no failure message

I wasn't able to reproduce this error. Are there any packages installed?

@pantoniadis this is a bug with our geometry kernel that will be fixed at the next Revit hotfix and in the upcoming Revit 2024 global launch release. We sincerely apologize for missing this.

This unfortunately means we cannot resolve it in Dynamo alone, and have to wait for said fix to propagate outwards.

It should also be fixed in Revit 2023.1.2.

Thank you!
