Getting the surface area of a face (like the measure tool) in Code

[NachoShaw]

Hi

i need to be able to get the surface area of a part. i can get it using the measure tool and selecting the 'Measure Area' command but can i get the value i need via code only?

i actually need to iterate all faces on a part to find the largest one. 

Does anyboby have any ideas or can help?

Thanks

Something like so (VB.NET). Covers parts with multiple solid bodies.

Dim doc As PartDocument = Nothing

Dim bodies As SurfaceBodies = Nothing

Dim faces As Faces = Nothing

Dim maxArea AsDouble = 0.0

Dim faceArea AsDouble = 0.0

Dim bigFace As Face = Nothing

doc = <get a reference to part document>

bodies = doc.ComponentDefinition.SurfaceBodies

For Each body As SurfaceBody In bodies

    For Each bodyFace As Face In body.Faces

        faceArea = bodyFace.Evaluator.Area

        If faceArea > maxArea Then

            bigFace = bodyFace

            maxArea = faceArea

        End If

    Next

Next

Hi

Thanks for that. I had managed to muster up a routine and I had found the evaluator.area about 2 hours ago. I made a variable to store the area on a condition that it could only be stored if the value was higher than the previously stored area. That way I would filter the highest (largest) face. Your code looks smaller than mine 🙂

I added in a small routine to highlight the largest face at the end but I'm struggling with making it a selected face 🙂


Thanks for the code
