The [[Image:Sketcher_ConstrainRadius.svg|24px]] [[Sketcher_ConstrainRadius|Sketcher ConstrainRadius]] tool fixes the radius of circles, arcs and [[Sketcher_CreateBSpline#Notes|B-spline weight circles]].
This constraint constrains the value of the radius of a circle or arc to have a specific value. If more than one circle or arc is selected before launching the command :
* If the constrain is applied in 'Reference' mode, a new reference constrain is added to each object separately according above rules
* If the constrain is applied in 'Normal' (driving) mode, following rules are applied
** A reference constrain is applied separately on each object which is an external geometry
** {{Button|[[File:Sketcher_ConstrainEqual.svg|16px]] [[Sketcher_ConstrainEqual|Equal constrains]]}} are applied sequentially between all real/construction geometry objects and a dimensional constrain is applied to the first selected object according above rules
NB : B-spline poles can't be mixed with other object type in the selection

# Pick one or more circles or arcs.
# Press the {{Button|[[File:Sketcher_ConstrainRadius.svg|16px]] [[Sketcher_ConstrainRadius|Constrain radius]]}} button.
# A pop up dialog opens to edit or confirm the value. Press {{Button|OK}} to validate. In case multiple circles/arcs were selected, all constraints will adopt this value. Edit their separate values by double-clicking on the dimension label in the 3D view; or in the Constraints list, double-click on the constraint or right-click and select '''Change value'''.
# Optionally the dimension label and line can be moved and rotated in the 3D view by clicking on the value and dragging while keeping the left mouse button pressed.

Popis

Tato vazba nastavuje hodnotu poloměru kružnice nebo oblouku na zadanou hodnotu. Najednou může být nastavena hodnota pouze pro jednu kružnici nebo jeden obklouk.

The Sketcher ConstrainRadius tool fixes the radius of circles, arcs and B-spline weight circles.

Postup


Kliknutím vyberte oblouk nebo kružnici v náčrtu ( vybraná položka bude mít tmavězelenou barvu).

Aplikujte vazbu kliknutím na ikonu vazby poloměru v nástrojovém pruhu Náčrtu nebo výběrem položky Vazba poloměru v submenu Vazby náčrtu v menu Náčrtu (nebo Návrhu dílu, závisí ve které pracovní ploše jste - Náčrt nebo Navrh dílu).

Poloměr je zafixován na aktuální hodnotu poloměru.
Hodnotu nastavení změníte buď dvojklikem na vazbu ve 3D zobrazení (změna barvy na červenou indikuje, že vazba je vybrána) nebo dvojklikem na vazbu v panelu vazeb záložky Nástroje v rozbalovacím pohledu.
Tím zobrazíte vyskakovací dialogové okno.

Zadáte požadovanou hodnotu poloměru do dialogového okna a kliknete na OK a tak nastavíte hodnotu vazby.

Vazba je nastavena na hodnotu zadanou v dialogovém okně.

Continue mode

  1. Make sure there is no selection.
  2. There are several ways to invoke the tool:
    • introduced in version 1.0: If the Dimensioning constraints preference is set to Single tool (default): press the down arrow to the right of the button and select the Constrain radius option from the dropdown.
    • If this preference has a different value (and in version 0.21 and below): press the Constrain radius button.
    • Select the Sketch → Sketcher constraints → Constrain radius option from the menu.
    • introduced in version 1.0: Right-click in the 3D view and select the Dimension → Constrain radius option from the context menu.
    • Use the keyboard shortcut: K then R.
  3. For further steps see Sketcher ConstrainRadiam.

Run-once mode

See Sketcher ConstrainRadiam.

Scripting

Sketch.addConstraint(Sketcher.Constraint('Radius', ArcOrCircle, App.Units.Quantity('123.0 mm')))

The Sketcher scripting page explains the values which can be used for ArcOrCircle, and contains further examples on how to create constraints from Python scripts.
