Step 3: Follow the tutorial How to Merge Dot3D Frames Into a Single Unified Point Cloud in CloudCompare to prepare your e57 file to be imported.

Step 4: Select "Content Drawer" in the bottom left hand of your project, then select "Import"

Step 5: Select your file, then press "Open"

Step 6: You can now drag your imported point cloud into the viewport to put it in your project

Your scan should now be viewable and editable in your projects viewport
