Dome
Menu access: Shape | Other shapes | Dome
Description:
Allows you to create a dome shape with one guide curve and one (or more) section curve(s).
General philosophy:
Select the guide curve (that will be the base of the dome).
Select the section(s) curve(s) and confirm with OK .
Available option(s):
When curves are closed, you can choose
the type of shape to create with the option Type=
SOLID or
SURFACE
TYPE . When you choose the solid type, the created shape will be
solid if possible. If not, not any message will appear.
The option Curves=
VISIBLE or
HIDDEN
allows
you to keep visible or not the curves after the dome is created.
The list 
allows you
to choose the correspondence between the curves
The option 
allows
you to choose the type of synchronization
between the curves.
The option MAKE
SECTIONS allows
you to generate the sections (non associative) that would be used
to create the dome. In this case the dome is not made. These sections
can be used to give you an idea of the shape that would be generated.
They can as well be used as section curves to improve or modify the dome.
The DIRECTION
allows
you to choose another direction for the dome axis (represented by a red
dotted line).
TopSolid automatically choose an
axis by the following way:
If the guide curve is planar, the dome axis is define by the normal of this plane.
If the guide curve is not planar, 3 guide curves will be necessary to define the axis.The plane that will define it will be the average of the planes define at the top of the dome by the tangent to the section curves on this point.
Example(s):
Specific point(s):
The dome axis is used as reference
to calculate the sections of the dome. It can be compared with a revolution
axis.
The section curves can be selected
in any order.
The section curves
must meet together at the same point: the top of the dome.
If the guide curve is open:
If the section curves number is superior to 2, the dome will be made between the first and the last section curve; so it would not inevitably be made all along the guide curve.
If there is only one section curve, the dome will be made all along the guide curve.
Available modification(s):
By using the icon 
,
you can:
Create the section of the shape.
Change the correspondence and the synchronization with the CORRESPONDENCE button.
Change the direction of the dome.
Change the shape type ( solid or surface type).
