You can configure settings that control how lines display when they cross each other and the behavior of grips for a selected schematic line. 
Drawing behaviors you can configure include:
- End connection behavior for valves and inline instruments
- Display style of crossing lines
- Behavior of a gap symbol and scale
- Standoff distance between a line and a component
- Orthogonal and implied cornering behavior of schematic lines
- Display behavior of vertex grips
- Connection behavior of inline components when the component moves
