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 > 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.
