The Diameter Dimension tool adds a diameter dimension to a View. The dimension may be applied to any circular in the drawing. The distance will initially be the projected distance (ie as shown on the drawing), but this may be changed to the actual 3D distance using the {{Button|[[Image:TechDraw_LinkDimension.svg|16px]] [[TechDraw_LinkDimension|TechDraw LinkDimension]]}} tool.
The '''TechDraw DiameterDimension''' tool adds a diameter dimension to a View. The dimension may be applied to any edge which is a circle or circular arc.

==Применение==

# Select a circular edge in the drawing. (Note some arcs which appear to be circular are actually ellipses or BSplines. You cannot make a diameter dimension in these cases)
# Press the {{Button|[[Image:TechDraw_DiameterDimension.svg|16px]] [[TechDraw_DiameterDimension|Diameter Dimension]]}} button
# A dimension will be added to the View. The dimension may be dragged to the desired position.
# If needed, add tolerances as described in [[TechDraw_Geometric_dimensioning_and_tolerancing#Tolerances|this page]].

To change the properties of a dimension object either double-clicking it in the drawing or in the [[Tree_view|Tree view]]. This will open the [[TechDraw_LengthDimension#Dimension_dialog|dimension dialog]].

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

{{Code|code=
