This
example shows snap on model building. The user is starting with
some imported IGES geometry. Using the icons, it is easy to put
a disk on the bottom, build up a cone, and place a cylinder on the
top.
Create
a disk on the bottom
Start
by selecting the center of the disk.
Next
select the point to define the Z-axis.
The
radius of the disk is input next.
The
user may then input the minimum radius of the disk. In this
example, the default of zero is input by simply selecting the
right mouse button.
The
next input is for the start angle. Again, the default is selected.
The
next input is for the stop angle. Again, the default is selected.
A
form comes up that allows the user to input nodal breakdowns,
optical properties, node ids, and active sides. In the example,
the active side is changed to down.
The
display active sides button is selected next. A blue side is
inactive, green = active, gold = active both, and dark blue
= active none.
We
return to wireframe mode and will next create a cone.
Create
a cone
The
cone is created by first selecting the center of the bottom
of the disk.
The
second input defines the Z-axis and the height of the cone.
The
third input is the radius of the base.
The
fourth is the radius of the top.
The
final inputs are for the start and stop angles. Again, the defaults
are accepted.
The
user changes the optical properties of the cone and also the
active sides (not shown).
The
display active sides button is selected to make sure the cone
is correct.
We
return to wireframe and will now place a cylinder on top of
the cone.
Create
a cylinder on top
The
first input for the cylinder is the center of the base.
This
is followed by the input for the height.
The
radius is selected next.
Again,
the defaults for the start and stop angles are accepted.
