 Create text and calculations
  
 Created Object:
  • Text
 
  offers the possibility to create dynamical texts. These texts can contain calculations, which automatically adjust when objects are moved.

After  Text has been clicked, an input dialogue for text opens up. If the dialogue gets closed it can be reopened by clicking on the board, as long as the symbol is still marked.

 

Text-dialogue

Input of text is done in the input field. Using the button "preview" either displays the preliminary text or returns an error message. The inital text position on the board can be specified in the input fields "x =" and "y =". If in addition an object is choosen from the list "position relative to" the text moves relative to this object. In this case the x,y-position will be a relative one.

In  Move-mode texts can be moved.
Texts can be changed using the dialogue  object properties. In this dialogue the position of text can be fixed by clicking "Text unmovable". Furthermore with the list "precision" the number of decimal digits of Calculations can be controlled.

Examples

  • <value>Dist(A,B)</value> produces 3.25
  • The distance is <value>Dist(A,B)</value>! produces The distance is 3.25!
