of the objects point towards the inside. This also means that any other objects cluttering the inner space will not be considered during this specific computation. Measure mesh area Similarly to the "measure mesh" function, clicking this button will compute the area of a given mesh. Just select the mesh and click the "Compute" button. Measure Angles When at least three control points have been selected, you can compute the angle between control points. The interface of the window that will appear will allow you to set control points as A,B and C and then compute the angles between the vectors BA and BC. A checkbox will allow to change the output to radiants or degrees. Drawing panel These functions are available only in 3DF Zephyr Aerial. Fromt he "Drawing" tab it is possible to create drwaing elements directly on the 3D model, which then can be exported into .DXF or .SHP. To create a new drawing elemnt, simply click the "Create new" (1) button - the new element will be automatically added to the "Drawing elements" section in the Project tab (2). Once an element has been created, the dropdown menu to select the current drawing element will be enabled (in this case, showing the only available drawing element, "Drawing Element 0", just below the "Create new" button). This allows to select and edit previously created drawing elements. When the drawing element has been selected, it is possible to navigate the scene to the desired position (eventually by making use of the "align orthographic camera" checkbox). When ready, it is possible to select the middle points that will define the shape of the drawn element, by picking them directly on the mesh using the "Select" button (3). You may also use the "continuous mode" checkbox that won't ask for many clicks (each for every middle point) but instead it will draw the line as long as the left click is kept pressed and the cursor is on top of the mesh. Press "ESC" to exit the drawing mode. It is possible to change the color of one (or more) drawing elements by selecting the desired elements from the "drawing elements" section in project tab (2) by right clicking on the selection and then selecting "Change color selected"
