18.1 Edit and transform

Edit and transform

Some special functions of track can help you establish experiments more quickly . These special functions can be used after selecting a track , Enter by clicking the right mouse button . Please note that , When drawing or inheriting paths freely , The options available are different .

Free draw path menu

A menu like this will show the free drawing path ：                          

Fixed to the construction area

Insert additional way points

reverse

Convert an arc into a Bezier curve

Fixed to the construction area

The track will be fixed in the construction area , Once checked , The track will be fixed on the build area , Prevent it from inadvertently sliding over the construction area .

Insert additional path points

After manually creating a path or converting to a freely drawn path , Additional path points can be inserted . The path point will be inserted into （ Or close to ） Mouse position . By " Split in two " The attributes of the line segment will be inherited by the two new line segments . Once a path point is inserted , Edit mode will open automatically , Easy to drag control points . You can insert control points on all 2D line segments . The first road section with banking function drawn on the road is 3D Section （ Intersections and roundabouts have no banking function ）. Cannot be in 3D Insert a waypoint on the road segment .

reverse

Reverse the driving direction on the track .

Convert an arc into a Bayesian curve

In order to make the lateral acceleration transition between the two sections smoother , You can make an arc
