Descriere

Constrângerea de egalitate forțează două sau mai multe segmente de linie, o poli-linie sau un dreptunghi să aibă o lungime egală. Dacă se aplică la arce sau cercuri, razele sunt constrânse să fie egale. Nu poate fi aplicată primitivelor geometrice care nu sunt de același tip (de exemplu, segmente de linie și arcuri de cerc).

Usage

See also: Drawing aids.

Continue mode

  1. Make sure there is no selection.
  2. There are several ways to invoke the tool:
    • Press the Equal Constraint button.
    • Select the Sketch → Constraints → Equal Constraint option from the menu.
    • introduced in 1.0: Right-click in the 3D View and select the Constrain → Equal Constraint option from the context menu.
    • Use the keyboard shortcut: E.
  3. The cursor changes to a cross with the tool icon.
  4. Select two edges of the same type.
  5. A constraint is added.
  6. Optionally keep creating constraints.
  7. To finish, right-click or press Esc, or start another geometry or constraint creation tool.

Run-once mode

  1. Select two or more edges of the same type.
  2. Invoke the tool as described above, or with one of the following additional options:
    • introduced in 1.0: Right-click in the 3D View and select the Equal Constraint option from the context menu.
    • Right-click in the Elements section of the Sketcher Dialog and select the Equal Constraint option from the context menu.
  3. Depending on the selection one or more constraints are added.

Scripting

Sketch.addConstraint(Sketcher.Constraint('Equal', Edge1, Edge2))

The Sketcher scripting page explains the values which can be used for Edge1 and Edge2 and contains further examples on how to create constraints from Python scripts.

Notes

  • Using horizontal and vertical dimensions instead of equal constraints can prevent flipping. Points constrained by these dimensions will only switch places if the sign of their value is changed. To keep the dimensions equal the constraints can be linked to each other with an expression, or to the same value in a VarSet or spreadsheet.
