5. Now, let's perform a few more extrusions and scales in order to shape the exterior
part of the ire according to the blueprint. The inner part of the ire can be modeled
by following the same steps as explained for the exterior.
With the ire modeled, we now need to add the rim.
6. For that we just need to select the inner circle of the exterior part of the ire,
duplicate it, and press
Escape
to leave it posiioned exactly where the border of the
ire is. Then perform three extrusions and scales to shape the outer ring of the rim;
make sure to finish this "ring" with an extrusion that goes inside the wheel.
7. Now is a good ime to check the shape of the ire and the part of the rim that we
created and perform any necessary tweaks.
To finish the process, we just need to create the cover of the rim, which has a star
shape.
8. For this, we select one of the circles belonging to the ring of the rim, duplicate
it, scale it down to be just a bit smaller than the ring of the rim that we already
created, and move it in the posiive direcion of the X axis (in front view is easier).
9. Next, we select all the edges in this duplicated circle, extrude them, press
Escape
and then scale them down by a factor of 0.3.
10. After that, we select every other edge in the outer circle of the patch that we are
working in, and then delete them (
Mesh → Delete → Edges
).
11. The inner part has to be illed. We start illing by selecing two opposite edges
on the inner circle and creaing a face between them. Then coninue creaing faces
parallel to this irst one unil the inner part gets completely illed with faces.
If we take a look at the blueprint, we will see that the shape of each arm of this
"star" is more even than the one we have now.
12. To get the arms to look more even, let's go selecing and scaling by a factor of 0.5 for
each one of the five edges that remain from the outer circle.
13. Once that is done, we coninue by adding a trivial edge loop (with the
Loop Cut
and Slide
tool) cuing each arm across into two secions; once the ive arms
have this new edge inside, let's just select all these new edges and move them
slightly in the posiive direcion of the X axis. Now we can see the nice curved
shape that appears.
14. To inish the cover of the rim, we only need to sharpen the ip of each arm by adding
an edge loop parallel, and very close, to the rim.
15. With the shape completed, we just need to select all the edges that form
the enire border of this patch of polygons and then extrude them inwards,
just enough to give a good shape to the arms.
