Descrizione
Macro per visualizzare una sezione trasversale degli oggetti nella scena: il piano di sezione può essere spostato tramite una barra di scorrimento.
Uso
- Scaricare la macro da questa pagina e installarla nella directory delle macro,
- quindi utilizzare il menu per richiamare l'elenco delle macro e fare doppio clic su questa macro.
- Si visualizza una sezione di default e si apre una finestra che consente di impostare i parametri del sezionamento.
- Chiudendo la finestra pop-up si ripristina la scena allo stato precedente all'avvio della macro.

***************************************************************************
* *
* This widget makes an interactively moveable cross-section of the *
* currently visible objects in the currently active document. The *
* cross-sectioning plane is specified by its normal, and the cross- *
* section can be moved along that normal using a slider bar. It can *
* show the cross-section either as an outline or a view of the sliced *
* objects. To run the macro, first download it from this site and *
* install it in your macros directory, then use the menu to call up *
* your list of macros and double-click on this one. It will display *
* a default cross-section and pop up a window to enable you to set *
* the cross-sectioning parameters. Closing the pop-up window will *
* restore the scene to its previous state before the macro was *
* started. *
