Linear dimensions based on edges and radial dimensions are parametric. This means that they will update if the measured edge is modified. Measured edges can belong to Draft objects but also to solid bodies. Angular dimensions are not parametric.
The tool can measure edges or lines directly attached to solid bodies; if the body changes, the dimension updates itself. The tool can also measure a diameter or radius of curvature such as those produced by a [[Draft Arc]], or by the [[Part Fillet]], [[Sketcher CreateFillet]], and [[PartDesign Fillet]] operations.


The resulting dimension is placed in the 3D view, and is considered a Draft object. This object can be displayed on a [[TechDraw Workbench]] Page, using the [[TechDraw NewDraft]] or [[TechDraw NewArch]] tools. Alternatively, TechDraw has its own tools to display dimensions, such as [[TechDraw Dimension Length]] and [[TechDraw Dimension Radius]]; however, these tools are meant for preparing technical drawings, so they create the dimensions only in the drawing page, and not in the 3D view.
Draft Dimensions can be displayed on a [[TechDraw_Workbench|TechDraw Workbench]] page using the [[TechDraw_DraftView|TechDraw DraftView]] or [[TechDraw_ArchView|TechDraw ArchView]] commands. Alternatively the [[TechDraw_Workbench|TechDraw Workbench]] offer its own dimension commands. But these create dimensions that are only displayed on the drawing page and not in the [[3D_view|3D view]].

=== Usage radial dimension ===
The dimension can be edited by double clicking on the element in the tree view, or by pressing the {{Button|[[Image:Draft Edit.svg|16px]] [[Draft Edit]]}} button. Then you can move the points to a new position.


# Optionally select a circular edge in the [[3D_view|3D view]].
The measuring points can be changed after creation by changing the start and end properties.
# There are several ways to invoke the command:
#* Press the {{Button|[[Image:Draft_Dimension.svg|16px]] [[Draft_Dimension|Draft Dimension]]}} button.
#* Select the {{MenuCommand|Annotation → [[Image:Draft_Dimension.svg|16px]] Dimension}} option from the menu.
#* Use the keyboard shortcut: {{KEY|D}} then {{KEY|I}}.
# The {{MenuCommand|Dimension}} task panel opens. See [[#Options|Options]] for more information.
# If you have not yet selected an edge do one of the following:
#* Press {{KEY|E}} or the {{Button|[[Image:view-select.svg|16px]] Select edge}} button and select a circular edge in the [[3D_view|3D view]].
#* Hold down the {{KEY|Alt}} key, select a circular edge in the [[3D_view|3D view]] and release the {{KEY|Alt}} key.
# To position the dimension line do one of the following:
#* For a diameter dimension:
#** Pick a point in the [[3D_view|3D view]], or type coordinates and press the {{Button|[[Image:Draft_AddPoint.svg|16px]] Enter point}} button.
#* For a radial dimension:
#** Hold down the {{KEY|Shift}} key and pick a point in the [[3D_view|3D view]].


=== Usage angular dimension ===
The position of the measurement line can also be changed after creation by changing its direction property.


# There are several ways to invoke the command:
<div class="mw-translate-fuzzy">
#* Press the {{Button|[[Image:Draft_Dimension.svg|16px]] [[Draft_Dimension|Draft Dimension]]}} button.
== Tipuri de cote care pot fi alese ==
#* Select the {{MenuCommand|Annotation → [[Image:Draft_Dimension.svg|16px]] Dimension}} option from the menu.
* '''Dimensiuni liniare''': alegeţi oricare 2 puncte sau orice margine dreaptă în vreme ce apăsaţi tasta {{KEY|ALT}}.
#* Use the keyboard shortcut: {{KEY|D}} then {{KEY|I}}.
* '''Dimensiuni orizontale/verticale''': prin apăsarea tastei {{KEY|SHIFT}} după selectarea primului punct.
# The {{MenuCommand|Dimension}} task panel opens. See [[#Options|Options]] for more information.
* '''Dimensiunea diametrului''': prin alegerea unei margini curbe când se apasă tasta {{KEY|ALT}}.
# Do one of the following:
* '''Dimensiunea razei''': prin alegerea unei margini curbe când se apasă tasta {{KEY|ALT}}, iar apoi se apasă tasta {{KEY|SHIFT}}.
#* Press {{KEY|E}} or the {{Button|[[Image:view-select.svg|16px]] Select edge}} button and select a first straight edge in the [[3D_view|3D view]]. Repeat this to select a second straight edge.
* '''Dimensiuni ale unghiurilor''': prin alegerea a două margini drepte când se apasă tasta {{KEY|ALT}}.
#* Hold down the {{KEY|Alt}} key, select two straight edges in the [[3D_view|3D view]] and release the {{KEY|Alt}} key.
</div>
# To position the dimension arc pick a point in the [[3D_view|3D view]].
# The displayed angle depends on the edges and the picked point.


=== Options ===
* Linear dimensions: hold the {{KEY|Alt}} key, or click on the {{Button|[[Image:view-select.svg|16px]] select edge}} button, and pick a straight edge, then pick a second point to draw the dimension line parallel to that edge.
:{{emphasis|Note:}} you can also pre-select the edge before calling the tool.
* Horizontal and vertical dimensions: pick one point, then pick a second point, then hold the {{KEY|Shift}} key and move the pointer horizontally or vertically, then pick a third point to draw the dimension line parallel to either the X axis or the Y axis.
:{{emphasis|Note 1:}} click and hold {{KEY|Shift}} and move the pointer in different directions many times until the dimension line aligns to the desired axis. Clicking {{KEY|Shift}} while the pointer is far from the first point will usually align the dimension to the X axis; if the pointer is close to the first point it will usually align the dimension to the Y axis.
:{{emphasis|Note 2:}} instead of picking two points, pick an edge while holding {{KEY|Alt}}.
* Diameter dimensions: hold the {{KEY|Alt}} key and pick a curved edge, then pick a second point to draw the dimension line.
** Radius dimensions: hold the {{KEY|Alt}} key and pick a curved edge, then hold the {{KEY|Shift}} key and pick a second point to draw the dimension line.
* Angular dimensions: hold the {{KEY|Alt}} key and then pick two straight edges, then pick a point between the two edges to show the acute or obtuse angle, or elsewhere to show a supplementary or explementary angle.
:{{Emphasis|Note:}} the displayed angle largely depends on the original position of the selected edges. If you would like to display a particular angle, you may have to add auxiliary [[Draft Line]]s that extend from the original edges, and measure these extensions.


The single character keyboard shortcuts available in the task panel can be changed. See [[Draft_Preferences|Draft Preferences]]. The shortcuts mentioned here are the default shortcuts (for version 0.22).
{{Emphasis|Note:}} by pre-selecting an edge, or by picking it with {{KEY|Alt}} or {{Button|[[Image:view-select.svg|16px]] select edge}}, the dimension will become {{emphasis|parametric}}, that is, it will remember which edge it is bound to. If the endpoints of that edge move later on, the dimension will follow them, and adjust the displayed measurement.

To create a Draft Dimension use the {{incode|make_dimension}} method ({{Version|0.19}}) of the Draft module. This method replaces the deprecated {{incode|makeDimension}} method.
The Dimension tool can be used in [[macros]] and from the [[Python]] console by using the following function:

{{Code|code=
{{Code|code=
Dimension = makeDimension(p1, p2, p3=None, p4=None)}}
dimension = make_dimension(p1, p2, p3=None, p4=None)}}

There are various ways to invoke this function, depending on the arguments passed to it:

Description

Descriere

Unealta Dimensiune trasează o dimensiune de cotare în documentul curent prin desemnarea a două puncte care definesc distanţa de măsurat şi un alt treilea punct, care determină locul pe unde trece linia de cotare.

Linear dimensions based on edges and radial dimensions are parametric. This means that they will update if the measured edge is modified. Measured edges can belong to Draft objects but also to solid bodies. Angular dimensions are not parametric.

Draft Dimensions can be displayed on a TechDraw Workbench page using the TechDraw DraftView or TechDraw ArchView commands. Alternatively the TechDraw Workbench offer its own dimension commands. But these create dimensions that are only displayed on the drawing page and not in the 3D view.

Usage linear dimension

Instrucţiuni de folosire

  1. Apăsaţi butonul (Ciornă Dimensiune) ori tastele D, apoi I.
  2. Alegeţi cu un clic un punct din vederea 3D sau introduceţi manual coordonatele de la tastatură.
  3. Daţi un clic în spaţiul 3D ca să alegeţi al doilea punct ori introduceţi coordonatele manual.
  4. Alegeţi al treilea punct cu un clic ori introduceţi-i coordonatele.

Usage radial dimension

  1. Optionally select a circular edge in the 3D view.
  2. There are several ways to invoke the command:
    • Press the Draft Dimension button.
    • Select the Annotation → Dimension option from the menu.
    • Use the keyboard shortcut: D then I.
  3. The Dimension task panel opens. See Options for more information.
  4. If you have not yet selected an edge do one of the following:
    • Press E or the Select edge button and select a circular edge in the 3D view.
    • Hold down the Alt key, select a circular edge in the 3D view and release the Alt key.
  5. To position the dimension line do one of the following:
    • For a diameter dimension:
      • Pick a point in the 3D view, or type coordinates and press the Enter point button.
    • For a radial dimension:
      • Hold down the Shift key and pick a point in the 3D view.

Usage angular dimension

  1. There are several ways to invoke the command:
    • Press the Draft Dimension button.
    • Select the Annotation → Dimension option from the menu.
    • Use the keyboard shortcut: D then I.
  2. The Dimension task panel opens. See Options for more information.
  3. Do one of the following:
    • Press E or the Select edge button and select a first straight edge in the 3D view. Repeat this to select a second straight edge.
    • Hold down the Alt key, select two straight edges in the 3D view and release the Alt key.
  4. To position the dimension arc pick a point in the 3D view.
  5. The displayed angle depends on the edges and the picked point.

Options

The single character keyboard shortcuts available in the task panel can be changed. See Draft Preferences. The shortcuts mentioned here are the default shortcuts (for version 0.22).

Opţiuni

  • Apăsaţi tasta X, Y sau Z după alegerea unui punct ca să constrângeţi următorul punct pe axele de coordonate date.
  • Ca să introduceţi coordonatele manual, pur şi simplu tastaţi numerele, apoi apăsaţi tasta ENTER după fiecare desemnare a componentei X, Y şi Z.
  • Când desenaţi, apăsaţi tasta CTRL ca să forţaţi ancorarea punctului în cea mai apropiată locaţie de ancorare, independent de distanţă.
  • Apăsând SHIFT creaţi o constrângere a dimensiunii orizontale sau verticale sau, când operaţi cu linii curbe, puteţi să comutaţi între diametru şi rază.
  • Apăsaţi tasta R sau daţi un clic pe pătrăţel ca să bifaţi/anulaţi butonul Relativ. Dacă modul Relativ este pornit, coordonatele următorului punct se relaţionează faţă de cele ale ultimului punct. Dacă opţiunea nu este selectată, coordonatele sunt absolute şi se referă la punctul de origine (0,0,0).
  • Apăsaţi tasta T sau daţi un clic pe pătrăţel ca să bifaţi/anulaţi butonul Continuă. Dacă modul Continuă este pornit, veţi putea continua să desenaţi dimensiuni de cotare, una după alta, care împart aceeaşi linie de bază.
  • Apăsaţi tasta ESC ori butonul Cancel ca să abandonaţi utilizarea comenzii Linie.
  • Prin alegerea cu tasta ALT a unei margini existente, în locul introducerii valorilor punctelor de măsurare, dimensiunea devine parametrică şi îşi va aminti de care margine este legată. Dacă, ulterior, marginea se va schimba, dimensiunea o va urmări.
  • Dacă o margine este selectată înainte de demararea comenzii Dimensiune, cotarea creată va fi de asemenea parametrică.
  • Direcţia liniei de cotare poate fi schimbată ulterior, prin modificarea proprietăţilor din caseta "Direcţie".

A Draft Dimension object is derived from an App FeaturePython object and inherits all its properties. The following properties are additional unless otherwise stated:

Data linear and radial dimension

Dimension

  • DateDimline (VectorDistance): specifies the point through which the dimension line passes.
  • DateLinked Geometry (LinkSubList): specifies the object and its subelement(s) the dimension is linked to.
  • DateNormal (Vector): specifies the normal of the plane of the text.
  • Date (hidden)Support (Link): specifies the measured object.

Linear/radial dimension

  • DateDirection (Vector): specifies the direction of the measurement.
  • DateDistance (Length): (read-only) specifies the value of the measurement.
  • DateEnd (VectorDistance): specifies the end point of the measurement.
  • DateStart (VectorDistance): specifies the start point of the measurement.

Radial dimension

  • DateDiameter (Bool): specifies if a radial dimension is displayed as a diameter dimension. Not used for linear dimensions.

Data angular dimension

Angular dimension

  • DateAngle (Angle): (read-only) specifies the value of the measurement.
  • DateCenter (VectorDistance): specifies the center of the measurement.
  • DateFirst Angle (Angle): specifies the start angle of the measurement.
  • DateLast Angle (Angle): specifies the end angle of the measurement.

Dimension

  • DateDimline (VectorDistance): specifies the point through which the dimension arc passes.
  • Date (hidden)Linked Geometry (LinkSubList): not used.
  • Date (hidden)Normal (Vector): specifies the normal of the plane of the dimension.
  • Date (hidden)Support (Link): not used.

View

Annotation

  • VizualizareAnnotation Style (Enumeration): specifies the annotation style applied to the dimension. See Draft AnnotationStyleEditor.
  • VizualizareScale Multiplier (Float): specifies the general scaling factor applied to the dimension.

Display Options

  • VizualizareDisplay Mode (Enumeration): specifies how the text is displayed. If it is World the text will be displayed on a plane defined by the DateNormal of the measurement. If it is Screen the text will always face the screen. This is an inherited property. The mentioned options are the renamed options (introduced in version 0.21).

Graphics

  • VizualizareArrow Size (Length): specifies the size of the symbols displayed at the ends of the dimension line or arc.
  • VizualizareArrow Type (Enumeration): specifies the type of symbol displayed at the ends of the dimension line or arc, which can be Dot, Circle, Arrow, Tick or Tick-2.
  • VizualizareDim Overshoot (Distance): specifies the additional length added to the dimension line. Not used for angular dimensions.
  • VizualizareExt Lines (Distance): specifies the length of the extension lines that go from the dimension line to the measured points. Use 0 for full extension lines. A negative value defines the gap between the ends of the extension lines and the measured points. A positive value defines the maximum length of the extension lines. Only used for linear dimensions.
  • VizualizareExt Overshoot (Distance): specifies the additional length of the extension lines beyond the dimension line. Not used for angular dimensions.
  • VizualizareFlip Arrows (Bool): specifies whether to flip the orientation of the symbols at the ends of the dimension line or arc. Only works if the symbols are arrows.
  • VizualizareLine Color (Color): specifies the color of the dimension line or arc, and the arrows.
  • VizualizareLine Width (Float): specifies the width of the lines or arc belonging to the dimension.
  • VizualizareShow Line (Bool): specifies whether to display the dimension line. Does not affect the display of extension lines and overshoots. Not used for angular dimensions.

Text

  • VizualizareFlip Text (Bool): specifies whether to flip the orientation of the text.
  • VizualizareFont Name (Font): specifies the font used to draw the text. It can be a font name, such as Arial, a default style such as sans, serif or mono, a family such as Arial,Helvetica,sans, or a name with a style such as Arial:Bold. If the given font is not found on the system, a default font is used instead.
  • VizualizareFont Size (Length): specifies the size of the letters. The text can be invisible in the 3D view if this value is very small.
  • VizualizareOverride (String): specifies a custom text to display instead of the actual measurement. Use the string $dim inside the text to include the measurement.
  • VizualizareText Color (Color): specifies the color of the text. introduced in version 0.21
  • VizualizareText Position (VectorDistance): specifies the position of the text in absolute coordinates. [0, 0, 0] will display the text in its default position near the dimension line or arc.

Units

  • VizualizareDecimals (Integer): specifies the number of decimal places to display for the measurement.
  • VizualizareShow Unit (Bool): specifies whether to display the unit next to the numerical value of the measurement. Not used for angular dimensions.
  • VizualizareUnit Override (String): specifies the unit in which to express the measurement, for example, km, m, cm, mm, mi, ft, in or arch for arch units. Leave this blank to use the default unit. Not used for angular dimensions.

Scripting

Scripturi

Unealta Dimensiune poate fi folosită în macro-uri şi de la consola python cu ajutorul funcţiei următoare:

To create a Draft Dimension use the make_dimension method (introduced in version 0.19) of the Draft module. This method replaces the deprecated makeDimension method. 

dimension = make_dimension(p1, p2, p3=None, p4=None)

There are various ways to invoke this method, depending on the arguments passed to it: 

dimension = make_dimension(p1, p2, p3=None)
dimension = make_dimension(object, i1, i2, p4=None)
dimension = make_dimension(object, i1, mode, p4=None)
  • Creează un obiect Dimensiune a cărui linie de dimensiune trece prin punctul p3.
  • Obiectul Dimensiune preia lăţimea şi culoarea de trasare setate în bara de comandă.
  • Există mai multe căi de a crea o dimensiune, în funcţie de necesităţile dorite de utilizator:
  1. (p1,p2,p3): creează o dimensiune standard de la p1 la p2.
  2. (object,i1,i2,p3): creează o dimensiune legată de un obiect dat, măsurând distanța dintre vârfurile indexate i1 și i2.
  3. (object,i1,mod,p3): creează o dimensiune legată de un obiect dat, i1 reprezintă indicele marginii (curbei) de dimensionat, iar modul este fie "rază", fie "diametru". Redă obiectul nou creat.

To create an angular dimension use the following method: 

dimension = make_angular_dimension(center, angles, p3, normal=None)
dimension = make_angular_dimension(center, [angle1, angle2], p3, normal=None)
  • din centrul dat, creează o dimensiune unghiulară, bazată pe o listă de unghiuri prestabilite, care trece prin p3.
  • redă obiectul nou creat.

The view properties of dimension can be changed by overwriting its attributes; for example, overwrite ViewObject.FontSize with the new size in millimeters.

Exempluː 

import FreeCAD as App
import Draft

doc = App.newDocument()

p1 = App.Vector(0, 0, 0)
p2 = App.Vector(1000, 1000, 0)
p3 = App.Vector(-2500, 0, 0)
dimension1 = Draft.make_dimension(p1, p2, p3)
dimension1.ViewObject.FontSize = 200

polygon = Draft.make_polygon(3, radius=1000)
doc.recompute()

p4 = App.Vector(-2000, 1500, 0)
dimension2 = Draft.make_dimension(polygon, 1, 2, p4)
dimension2.ViewObject.FontSize = 200

center = App.Vector(2000, 0, 0)
p5 = App.Vector(3000, 1000, 0)
angle1 = 45
angle2 = 10
dimension3 = Draft.make_angular_dimension(center, [angle1, angle2], p5)
dimension3.ViewObject.FontSize = 200

dimension4 = Draft.make_angular_dimension(center, [angle2, angle1], p5*1.2)
dimension4.ViewObject.FontSize = 200

doc.recompute()
