First
things first, this tutorial requires
the basic knowledge of rhino and
if you know more than that, well,
thats good for you. ;)
When
i start i always start with my template
set to milimeters.
My
grid snap spacing set to 0.25.
My
tolerances set to (from top to down)
0.001, 0.001, 0.01.
And
finally the custom render settings
of (again, top to down) 20, 6, 0.025,
2, 0, 0.
Now,
on to the modeling!
Setup
two circles, which should be the
wheels and ofcourse maintain the
distance between em (wheelbase).
Ok, now in the side view, draw a
curve for the lower shape of the
car. Now on a sidenote, since im
makin an exotic type of car, the
lower part of the car is close to
the ground but if youre makin a
normal type of car simply put that
line higher.
Make
sure you got your curves setup
like mine. If you wonder how
i got my curves to touch eachother,
well, most of the time i got
osnap "near" and
"end" on.
Draw
a profile curve from the top
curve to the bottom curve
somewhat like mine and sweep2rail
it.
Draw
another front curve starting
at the end of the lower part
of the profile curve and sweep2rail
that too.
Now
select the front curve and
split it with the 2nd top
curve.
Draw
2 profile curves on both top
curves and sweep2 rail em.
Now,
i joined the 3 made surfaces
but since my fillet from the
front to side surface failed
were gon have to find a way
to make it nice and smooth
anyway, if it works for you
you can skip this part. Explode
the surface. Since we still
got the profile curve, select
the profile curve and rebuild
it, make sure it has about
15 points, turn the points
on (f10) select the lower
point and drag it to make
the curve longer, do this
also on with the top poiint
but make sure its still the
shape of the original curve,
just slightly longer on both
sides.
Now
that we done that, select
the pipe tool and for thickness
on both sides select 1 (which
originally would be the size
of my fillet) select the front
and side surface and split
the pipe surface out of it,
select the splitted out surface
and delete it, now blend the
edge curves, NOT blendsrf
but just blend, do this on
the lower part and top part.
When
you got the 2 curves, select
the top surface and split
the upper curve out of it,
now select sweep2rail, select
both edge curves and use the
blend curves as profile curves,
in the box select tangency
for a and b so the made surface
flows nicely without any seems.
Now
join all 4 surfaces mirror
em so you got both sides and
it should look something like
this.
Select
dup edge cope the edges shown
in the image and join em since
we need to use this as a profile
curve.
