I’ve downloaded and edited a cloud processed project. I want to now upload the edited pointcloud which I did on PIX4D Desktop. When I click the replace button (in cloud) and go to upload the las file, there are more than one las files, 7 in fact (………part\_1.obj …….part\_2.obj etc) Do I click replace and upload each one separately? Thanks ---

Hi Kyle, you will need to merge the tiles of the point cloud and then upload as Pix4D cloud only accepts one las file when you upload: [https://support.pix4d.com/hc/en-us/articles/206364863-How-to-merge-the-Tiles-of-the-Point-Cloud](https://support.pix4d.com/hc/en-us/articles/206364863-How-to-merge-the-Tiles-of-the-Point-Cloud). Since you have already edited the point cloud, you have to save the project and then export cloud with the second method: 1. Click **View \> rayCloud**. 2. On the left sidebar, expand the Point Clouds layer and then the Densified Point Cloud list and right click on the densified point cloud to be merged. 3. Click **Export Point Cloud…** , the _Export Point Cloud_ pop-up appears. 4. Select _Merge Tiles Into One File_ to export the point cloud into one file.
