In Loq Airou you do not draw surfaces but rather edges that create surfaces when connected. Any edges that forms a triangle or quad will create a surface. When a polygon is created it will be turned in the same direction as its neighboring polygons. If there are no neighboring polygons it will be created facing the camera. If the neighboring polygons are facing different directions the modeler will create the polygon facing the direction of the majority of the neighbors (or towards the camera if there is tie). When a polygon is created it will delete neighboring polygons facing the wrong direction or polygons that break the two polygons per edge rule. This takes some time to get used to but turns out to be fairly intuitive. It is recommended that you as a user only use this creation tool to begin with until you are comfortable using it.

By clicking and dragging with the left mouse button you can create an edge. Both ends can be snapped to existing geometry to make connected edges. The edges are by default created in the view plane, perpendicular to your view point, the depth is depending on the last drawn point. However when you draw you can see three lines representing X, Y And Z and by drawing close to them you can draw in a specific dimensions and not just in the view plane.

If you which to draw in a plane perpendicular or one of the three axis (x/y, y/z or x/z) you can do by placing the camera in roughly one of the 3 axis. The software will then snap the drawing plane to the closest axis.

Note: at this time there is no indication to when the view is directed close enough to axis for the snap to be active, this will be addressed in future versions.

To create a continuous line consisting of multiple edges you can tap the middle mouse button while creating an edge to leave off vertexes.
