Pipe
Menu access: Shape | Pipe
Description:
Allows you to create a shape by sweeping a section curve along a guide curve.
General philosophy:
Select the guide curve.
Choose its direction.
Select the curve or text that will generate the shape.
Available option(s):
The option Follow=
EXISTING OPERATIONS or
SUBSEQUENT
OPERATIONS allows
you to set the degree of associativity of the resulting shape according
to the evolution of the guide curve.
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 Section
curves= VISIBLE or
HIDDEN
allows
you to keep visible or not the initial curve after the revolved shape
is created.
The option Corner
type= SHARP or
ROUNDED
allows
you to choose the type of the corners on a sharp angle of the guide curve.
The WIRE
SHAPE button allows you to directly create full tubes.
The TUBE
SHAPE button
allows you to directly create tubes with thickness.
Example(s):
Guide curve is blue, the section curve is red.
Specific point(s):
The guide curve can
be made of:
lines and/or arcs. A line and an arc consecutive must be tangent. The ideal function to create the guide curve is the function C-spline.
B-Spline curves, if they are "planar by bit". It is to say that the curve has to be made of a succession of planar curves.
The
section curve must be drawn at the origin
of the guide curve. It
is particularly important for closed guide curves.
You can select a text as initial
section curve.
It's possible to use several curves
either included one in another one either disjoined.
Available modification(s):
By using the icon 
,
you can change:
the diameter and the corner type for a wire shape pipe,
the diameter, the thickness and the corner type for a tube shape pipe,
the corner type for a pipe made on a spline.
