-====== Clean up a 3D scan ======
+====== Clean up a 3D scan made with the Occipital Structure scanner ======
+The 3D files from the Structure scanner often have holes and unwanted geometry. After following this guide you'll get a watertight model that is ready for (colour) 3D printing. A basic understanding of mesh manipulation in Blender is necessary.
+This guide uses Meshmixer, but here is a [[3d_modeling:blender:clean_up_occipital_3d_scan|guide]] that describes this process for Blender.
-==== Occipital Structure 3D scanner ====
+===== Open the file =====
-Cleaning up a 3D scan with Meshmixer is easy. Alternatively use [[3d_modeling:blender:clean_up_occipital_3d_scan|Blender]] for a more manual procedure with more control.
+The structure scanner delivers the 3D object in 3 parts:
+  - ''Model.obj'' is the 3D object
+  - ''Model.jpg'' is the texture file
+  - ''Model.mtl'' is a file that links the object to the texture.
+{{:structure_3d_scanner:cleanup_files.jpg?nolink|}}
+You only have to open the ''.obj'' file. The program will find the other files on its own:
+  - Click 'Import' and select the ''.obj'' file. Alternatively go to ''File > Import''.
 === Prepare model ===
-  - Import & orient the model upright: ''Edit > Transform''.
+  - Orient the model upright: ''Edit > Transform''.
   - Cut away unwanted geometry: ''Edit > Plane Cut''.

 === Join disconnected sections ===
+Objects from the structure scanner come in overlapping parts. This might cause problems for 3D printing.
   - Join the disconnected sections (blue lines indicate boundaries): ''Edit > Close Cracks''.
