Line Jump App
AutoCAD® Command WCSLJ
This app automates drawing Line Jumps, like Visio. There are four supported Jump styles: Arc, Gap, Square and 2 Sides. Line Jumps can be placed on any horizontal or vertical Lines or Polylines quickly by simply selecting the intersecting objects either directly or using a window/crossing. The app remembers your settings, making them the default settings for the next time when you use the app.
