3D lines

drawing tool this geometry shape is drawn using the 3d line tool it is mainly used for outlining areas drawing process select a class, move along the line or edge and place points where you want to have control points the points will be placed at the lowest point in the point cloud at that location continue placing points until you feel done with the object editing tools 3d add/ remove nodes docid\ bhregnctpdtc1nypmv4ra 3d scissor docid\ v1cqjjutnq7cfgbnzxire 3d detach nodes docid\ yc5hyhdj8rb6wbfcgq0 r adjust use the 3d transformation controls docid\ wnyknwuzumlisdj36t4k0 to adjust the placement of the line point to change the entire line, press shift before moving the controls see node and shape edit docid 9y0ax8qabl5ceikmqxrde and multiple nodes edit docid\ umf1ixrqo2cpgel0yqttl for more information extend the line you can extend a line from the start or end with keyboard shortcuts press 0 to extend the line from the end or shift+0 to extend the line from the beginning read more about an alternative way to extend the line here zoom to selected zoom to selected to quickly review the points along a line by pressing k step between points step between points using alt+n and alt+p reverse direction you can reverse the line direction by clicking on the 3d lane with the right mouse button and selecting "reverse direction " see direction indicator docid\ vg0rqvtpdkrett4osvwch for how to view lane direction indicators options closed lines 3d lines can be configured to automatically be closed this way the last node will always connect to the first and is visualized while drawing automation when in bird's eye view, the vertical position of created nodes will be set to the ground level derived classes the derived classes docid\ t7pvih7 6 q3nbueccdgf feature is a way to automatically generate 3d lines based on other lines, such as lane connections and centerlines
