Descriere
Această constrângere obligă valoarea razei unui cerc sau a unui arc de cerc să aibă o valoare specifică. Dacă este selectat mai mult de un cerc sau un arc de cerc înainte de lansarea comenzii, un dialog contextual vă va întreba dacă toate elementele selectate ar trebui să partajeze aceeași rază. În cazul unui răspuns afirmativ, se va adăuga o constrângere de rază și o equal length va fi adăugată la toate elementele. În negativ, vor fi create constrângeri separate de rază pentru fiecare cerc / arc, dar cu valori egale care vor fi editate separat după crearea.
The 
Sketcher ConstrainRadius tool fixes the radius of circles, arcs and B-spline weight circles.
Cum se folosește

Continue mode
- Selectați una sau mai multe cercuri sau arce e cerc.
- Apăsați butonul
Constrain radius . - Un dialog contextual se deschide pentru a edita sau a confirma vloarea. Apăsați OK pentru a valida.În cazul în care au fost selectate mai multe cercuri/arce, toate constrângerile vor adopta această valoare. Editați valorile lor separat făcând dublu clic pe cota/eticheta de dimensiuni din vizualizarea 3D; sau în lista Constrângeri, faceți dublu clic pe constrângere sau faceți clic dreapta și selectațiChange value.
- Opțional, eticheta/cota și linia de cotă pot fi mutate și rotite în vizualizarea 3D făcând clic pe valoare și tragând în timp ce mențineți apăsat butonul stânga al mouse-ului.

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.
