Macro Easy cutouts for Enclosure Design/it

Descrizione

Permette di creare delle aperture nei contenitori in un modo molto pratico
Basta selezionare una faccia dell'oggetto di base del ritaglio e la macro crea un clone del suo contorno esterno con un margine di 0,5 millimetri (impostato nella macro)
qui una demo con un contenitore Arduino Uno

Uso

Selezionare una faccia dell'oggetto di base del ritaglio e la macro crea un clone del suo contorno esterno con un margine di 0,5 millimetri (impostato nella macro)

Script
