Geometric Constraints Visible

The geometric constraints are displayed as dimension constraints or graphical symbols between elements, in points, or between points and elements. The dimension constraint or symbol indicates that there is a geometric constraint between the elements.

  • The dimension constraints are always visible. The dimension constraint is highlighted in blue when the geometric constraint is in effect. The fixed line is also highlighted in blue.

  • Other geometric constraints, for example, such as Parallel constraint, is displayed as graphical a symbol.

    The displayed symbol is highlighted in blue when the geometric constraint is in effect.

  • Set constraints visible as follows:

    Select > User Preferences > Drawings, Models.

    Select View > Show Constraints.

    Press the F9 key to toggle the visibility of the symbols.

    Meaning Symbol
    Midpoint
    Perpendicular
    Equal distance
    Equal radius
    Concentric
    Symmetry
    Tangential
    Parallel
  • In the drawing, unresolved constraints will be highlighted in red color. For example, if too many constraints are defined for the elements, the drawing is overdefined and the color of the constraint changes red.

    In the image below, the other dimension constraint is extra. Compare to the figure above. You can fix the situation by deleting the extra constraint.

Note:
  • If necessary, zoom the drawing in order to see the symbol.
  • View elements related to a constraint, by selecting Delete constraint in a Drawing
  • Select a graphical constraint symbol by clicking it. You can delete a constraint by using the Delete function or pressing the Delete key.
