This editing mode allows you to draw your geometry. Draw lines by clicking with the left mouse button (<b>LMB</b>) where you want your vertices. Depending on the toolbar buttons, the vertex you are drawing next will snap to the grid and/or to nearby geometry. You can change this behavior by holding down Shift and/or Control. Your drawing ends when you draw onto the first drawn vertex (making a closed polygon) or when you press your right mouse button (<b>RMB</b>).<br/>
Contrary to drawing in older editors, it is not required to draw in any specific way, such as drawing clockwise or drawing a complete polygon. You also do not need to traverse your existing lines when drawing a sector adjacent to existing geometry. The editor will solve any lines your drawing crosses, split sector you draw across and creates new sectors where needed.<br/>
This editing mode is one of the classic (2D) editing modes. This mode is volatile, which means that this mode returns to the previous stable mode when the map is saved or closed, either accepting or discarding your preview changes. You can access this mode by pressing <b>Control+D</b> in any classic mode.
