Creating a new 3D view with section box aligned to 2D crob box and depth

Here’s a section from a similar script I’ve written.

elevation = view.GenLevel.LookupParameter('Elevation').AsDouble()
vCrop = list(view.GetCropRegionShapeManager().GetCropShape())[0]
vCropPointsX = []
vCropPointsY = []
for x in vCrop:
    vCropPointsX.append(x.GetEndPoint(0).X)
    vCropPointsY.append(x.GetEndPoint(0).Y)
    vCropPointsX.append(x.GetEndPoint(1).X)
    vCropPointsY.append(x.GetEndPoint(1).Y)
minX = min(vCropPointsX)
minY = min(vCropPointsY)
maxX = max(vCropPointsX)
maxY = max(vCropPointsY)           

new_box = BoundingBoxXYZ()
new_box.Min = XYZ(minX, minY, elevation - 10)
new_box.Max = XYZ(maxX, maxY, elevation + 10)
v_name = view.Name
new_iso = DB.View3D.CreateIsometric(doc,threeDTypes[0].Id)
new_iso.SetSectionBox(new_box)
name_param = new_iso.LookupParameter('View Name')
name_param.Set('{} ISOMETRIC'.format(v_name))

This creates a 3D view cropped to the maximum extents of the view. The section box is always orthogonal to project north in the above code, if you want to look into rotated section boxes, you can dive into BoundingBoxXYZ.Transform.
