I have to produce a considerable number of accurate, high res, rectified images of the interior elevations of a fire damaged building from data captured with a DJI drone. First test looks promising but learning curve looks steep to get from there to finished product. Main stmbling block so far is orientation of the model and control/revision of wrongly stitched images. Can anyone suggest online learning resource or workflow examples for this task? Thanks, William. ---

Hi William, Thank you for contacting the Pix4D Support. Orientation is a common issue when you are doing indoor mapping/ vertical wall or so on. However, after processing step 1, you can orient the project to your requirement by using the " _ **New Orientation Constraint** _ " feature available on the software. For more information, I would recommend you to go through our support article on [How to orient a project](https://support.pix4d.com/hc/en-us/articles/205360385-How-to-orient-a-project?source=search).
