Potrebujem casto krat zmerat dlzku polyline. Pokial je len jedna tak to nieje problem. V Properties si pozriem hodnotu length. Pokial ich je viac a potrebujem sucet ich dlzok, tak ich najprv cez pEdit spojim do jednej a potom si pozriem vyslednu hodnotu length. Toto sa vsak da robit len za predpokladu ze tieto samostatne polyline nadvazuju na seba.

 

Ako mozem zistit sucet dlzok viacerych polyline, ktore niesu na seba priamo  nadvazujuce a vo vykrese tvoria samostatne useky?

 

Da sa to aj jednoduchsie ako naprogramovat to neako cez lisp?

Ak je jedina moznost lisp, vie mi niekto pomoct so scriptom pre takyto lisp?

 

Dakujem za ochotu a rady!

 

je to pomocou lispu a tu je script

 

je to z ineho fora, takze vdaka povodnemu autorovi.

 

;;;=======================[ Length.lsp ]=========================
;;; Author: Copyright© 2005 Charles Alan Butler

;;; Purpose: display the length of a selected objects
;;; and a running total
;;; Sub_Routines: -None
;;; Returns: -NA
;;;=============================================== ===============

I know there are many fine "Length" routines around.
This is my version and it allows the user to pick each object & displays
the length & a running total on the command line.
An option at start up lets the user optionally put the result in the drawing.
The text is placed at the user pick point and the current text style & layer are used.
The options for text insert are:
None - No text is inserted, this is the default
Each - Text is inserted after each object is selected
Total - Text is inserted only at the end of all selections & only the total is inserted.

Exit the routine by pressing Enter or picking nothing
Pressing C enter will clear the total
Pressing Enter while placing the text will skip the insert for that object.
