==Usage==

# Select a View or a collection of Edges in a View.
# Press the {{Button|[[Image:TechDraw_VerticalExtentDimension.svg|16px]] [[TechDraw_VerticalExtentDimension|Vertical Extent Dimension]]}} button
# A dimension will be added to the View. The dimension may be dragged to the desired position.

== Limitations ==

Dimension objects are vulnerable to the "[[Topological_naming_problem|topological naming problem]]". See [[TechDraw_LengthDimension|TechDraw LengthDimension]] for more information.

==Properties==

See [[TechDraw_LengthDimension#Properties|TechDraw LengthDimension]]. Exceptions noted below.

=== Data ===

* {{PropertyData|MeasureType}}: {{TRUE}} - based on 3D geometry or "Projected" - based on the drawing. Not normally manipulated directly by the end user. Not yet implemented for Dimension Vertical Extent.

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

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