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 .

How to use

  1. 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)
  2. Press the File:Dimension Diameter.png Dimension Diameter button
  3. A dimension will be added to the View. The dimension may be dragged to the desired position.

Options

None.

Properties

Template:TechDraw DimProps

Scripting

Diameter dimensions can be added to Pages using Python.

dim1 = FreeCAD.ActiveDocument.addObject('TechDraw::DrawViewDimension','Dimension')
dim1.Type = "Diameter"
dim1.References2D=[(view1, 'Edge1')]
rc = page.addView(dim1)

Notes

  • All Dimensions are extremely vulnerable to the infamous "topological naming" issue. It is not possible at this time to keep references to 2D (projected) or 3D (actual) geometrical objects in sync with changes in the model. It is recommended that Dimensions be added towards the end of the drawing creation process.
