In
order
to
get
code
calculations,
RISA-3D
and
RISA-2D
need
to
know
what
type
of
shape
would
be
most
similar
to
yours.
This
is
because
the
program
needs
to
use
the
correct
code
equations
for
your
shape
type.
You
can
easily
add
your
custom
shape
to
the
Cold
Formed
library
of
shapes.
First,
pick
a
similar
shape
type
(Channel,
Hat,
Zee,
etc.)
and
then
add
the
section
properties
into
the
Shape
Database.
You
can
calculate
the
section
properties
manually
or
use
RISASection
to
calculate
the
section
properties
for
you.
Step
1:
Select
a
similar
shape
type.
Step
2:
Click
Add
to
create
new
section.
Step
3:
Create
a
name
and
add
section
properties
to
the
start
shape.
Then,
click
OK.
Note:
This
step
is
the
first
attempt
at
creating
the
shape
and
the
section
properties
do
not
need
to
be
exact
just
yet
Step
4:
Select
the
new
shape
and
click
Edit.
Now
you
can
enter
in
all
the
section
proprieties
from
your
hand
calculations
or
the
RISASection
calculations…
