Descriere
Instrumentul pentru cote tip diametrue adaugă o cotă diametru unei imagini. Cota poate fi aplicată la orice cerc din desen. Distanța va fi inițial distanța proiectată(adică așa cum este reprezentată în desen), dar această distanță poate fi înlocuită prin distanța 3D reală utilizând instrumentul Link Dimension 
.
The Dimension Diameter 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 
Link Dimension tool.
Measuring a circle, indicating the diameter
Cum se folosește
- Selectați un cerc sau un arc de cerc în desen. (Notați că anumite arce de cerc apar ca fiind circulare dar de fapt sunt elipse sau curbe BSplines. Nu puteți realiza diametru dimension în aceste cazuri)
- Apăsați butonul
Dimension Diameter - O cotă/distanță va fi adăugată în View. Cota poate fi glisată până în poziția dorită.
- 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
Dimension Diameter 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 this page.
To change the properties of a dimension object either double-clicking it in the drawing or in the Tree view. This will open the dimension dialog.
Limitations
Dimension objects are vulnerable to "topological naming" issues. See the information in the TechDraw Dimension Length tool for more information.
Proprietăți
This object has the same properties as the TechDraw Dimension Length tool. See that tool for details.

Script
Cotele tip diametru pot fi adăugate la Pages utilizând Python.

The Dimension Diameter tool can be used in macros and from the Python console by using the following functions:
dim1 = FreeCAD.ActiveDocument.addObject('TechDraw::DrawViewDimension','Dimension')
dim1.Type = "Diameter"
dim1.References2D=[(view1, 'Edge1')]
rc = page.addView(dim1)
