Rig In 5 (Reset Tools Tab)

so, here we are!! now its time to talk about the Reset Tools, as i mentioned before
the porpuse of this features are to manage more faster our imported model to be rigged
to keep think organize i will work on the same Police Raptor Car Model imported earlier showed in Import Tab

what can we see here? if we compare World Coordinate Reference and Raptor Police Orientation
we can see the model has wrong orientation because the nose of the Raptor Police should be pointing
at -Y not +Y, so for this kind of issues we use the Turn Left and Right buttons

as you can see below:

this is because here we need the ROOT Empty of the Police Raptor Car Model name as
Sketchfab_model instead of the original name which is Ford F150 Raptor Police,
we can achieve this typing it by hand (a Boring Task) or by clicking Rename ROOT Empty
that is the only porpuse of this Operator, result is we save time avoiding to type it by hand:

Once we solve that Naming "rule" we can now fix the Raptor Police Orientation with easy

Fixing the model Orientation with 90 degress rotation:

after that in this case which is perfect to show the next Button call Fit Model

this operator is a bit more complex than just change the name of an Empty what it does create a new ROOT Empty base on bounding box of the selected object in our scene we only need always keep as active object one object "Wheel", i mean object we recognize as wheel shape why?, because this new ROOT empty created will Replace the Original One, positioned in the Lowest Vertex and Centered in the bounding box of the selected objects, so we this we can move all the model pieces an putting the plane(x, y) where this work as the ground of the world.

to see this better let see the World Axis Reference we already have in the scene as the ground so the Raptor Police should be over this, as shown below:

here is a closer view to see what is happening and taking a closer look, you may notice i used the Operator Twice because is flexible and you can used this as much as need to get the better result, which mean get that New ROOT empty as centered and align with the line where the "WHEELS" will be touching the ground

Now we can use Reset World Position and what it does is Apply the transform to the entire Empty Heriarchy so to see better which is the convenient in the case of our Raptor Police model is what you can see below:

by using the "Reset Wolrd Position" we can position the model above the ground in this case I said the ground is the World Axis Reference which is already in our scene:

Now Finally lets talk about the Clean Mesh Button

if we want to see better what Clean Mesh does we need to activate a property we don't mentioned yet because in our process we don't need to until now, what is that property? well the Live 3D view

Activating Live 3D View:

when we activate that property what happen is blender run a bunch of shading option at once for us:

now with live 3D View shading setting applied we can see better the shading issues that could come with the model we imported this is just to keep thinks clean in terms of geometry because this just do the following:
