+\page transform_fbx_to_dae Transform FBX to Collada
+
+This tutorial shows how to transform a mesh in fbx format to collada with Blender and and change its origin.
+
+You can download Blender +2.81 from [this web site](https://www.blender.org/download/).
+
+# Importing the FBX file
+
+Remove all the elements in the scene. You can select the elements pushing `Ctrl + Shift + left mouse button`
+from the list of elements that you can see in the right top corner of the Blender window.

+
+Then import your FBX model. `File -> Import -> Fbx (.fbx).`

+
+# Modify properties of the model
+
+Now we can edit some of the properties of the object.
+
+## Change the origin of the model
+
+Select the object by pushing the letter `a` and enter to `Edit mode` by pushing `Tab`.
+Select the part of the object at which you’d like to place the origin point (vertex, edge or face).
+When we are ready push `Shift + s` to bring up the *snap menu* and select `Cursor to active` to locate
+the Blender cursor (red/white circle thing) in the selected new place.
+Switch back to `Object Mode` and see the Blender cursor where your future origin is going to be.
+In the `Options` menu select `Origins` and then select in the object menu `Object -> Set Origin -> Origin to 3D Cursor`.
+Now your origin it's the desired place. We can move this origin to another place by editing the
+transform dialog.
