The Vertical Extent Dimension tool adds a linear dimension to a View. The dimension extends from the bottom most point on the selected objects to the top most point. A CosmeticVertex will be placed at each point.

The Vertical Extent Dimension tool can be used in macros and from the Python console by using the following functions:

selection = [(view1, 'Edge1'), (view1, 'Edge2')]  #or [] for all
hExtentDim = TechDraw.Dimension.makeExtentDim(selection, VERTICAL)
rc = page.addView(hExtentDim)
