Draft upgrade makes a face but calls it wire

[bernd]

- start FreeCAD
- make a sketch (a rectangle)
- use Draft upgrade on this sketch
- it will change to a face but it is still called wire

This is confusing IMHO. The tool Part --> make face from wire names the new object face.

Confirmed. But it upgrade to a Draft Wire with MakeFace = True.

Turn it to False, and it is a Draft Wire with 4 edges

First of all, the Draft Upgrade tool is a bit magical. By that I mean, it does things, but there is no defined behavior. What does "upgrade" mean? It means it tries to transform something into something "better". In most cases, this is intended to transform simple Part_Features (edges, wires, faces) into more complex Draft objects, like Draft Wires.

What you see is that the tool takes the shape of the sketch, extracts its points, and then creates a Draft Wire with those points. So the result is not just a Part.Face, it's a Draft Wire. A Draft Wire can be closed or open, and it can make a face or not. So, from the point of view of the tool, it does its work, because it creates a Wire (polyline). However you use that wire, whether you use its face or not, is a different question.
