Bug: Arch creation issues in Hammer

[HugoBDesigner]

1. When creating arches in Hammer, depending on the 2D view you have in focus during creation, its faces may have its normals inverted.

2. After resizing, sometimes an arch may become "offset" in such a way that aligning it to the grid requires resizing it.

3. The size of the arches entirely determines its accuracy and precision. Making a small arch will often provide subpar and imprecise geometry, with wonky angles. Creating an arch that is proportionally identical, but with much larger dimensions, then scaling it down, will create significantly better results. Their results should be consistent and uniform regardless of scale.
