With new type of elements to create any shape chassis, fuel consumption engines, randomly generated environment and bug fixes with saving
-Multi selecting elements is work with different way, now is visible with elements is select and can be select one, two or three elements.
When two or three elements are selected and key  is pressed new connection is create, with two element creating a bar and with three creating a plate.
Is same situation but with  key pressed, editor removing bar or plate connection, when are selected 2 or 3 elements.
-Now torque connectors is lost, if in vehicle is combustion or electric engine it got a torque, total sum of torque from all engines is split between wheels with selected 'is motor' option and propellers.
-Engines and rockets now need fuel to run, combustion and rocket use fuel from tank nodes and electric engine use power from batteries. In simulation mode is two strips, blue shows electric charge level and green fuel level. Its simple rule, more tanks more fuel supplies. Fuel tanks have different mass when they are full or empty. To refuel / recharge use cheaty key .
-Map is now random generated, on top of screen is number and button 'Generate terrain' when is pressed map change shape. Number is seed to map generator, one number create unique map shape, seed can be change by selected number and write own. To create random seed and map press  key.
-Calculation centre of mass and inertia tensor was changed, vehicle can dynamically change own mass.
-Bug with saving model with joints and connectors is fixed.
-Other bug fixes, graphics and functional improvements.
