Functional Details #!N #!N This module is intended for use with 
any module that creates lines (e.g., Streamline). #!N #!I0 #!N #!N 
#!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   line #!EF #!EF #!I50 #!N specifies the 
line that is to be changed into a tube. If a 
"normals" component is present (as would occur if the input field 
 #!F-adobe-times-bold-r-normal--18*   curl #!EF were used with Streamline or if the  #!F-adobe-times-bold-r-normal--18*   
flag #!EF parameter is set in Streamline), the tube shows a 
corresponding twist. To show the twist most effectively, use the Ribbon 
module. Excessive amounts of twist can produce a pinching effect. #!N 
#!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   diameter #!EF #!EF #!I50 #!N specifies the 
tube diameter in the same units as those of the original 
space. If this parameter is not specified, the module provides an 
appropriate value (1/50 of the diagonal of the boundary box of 
 #!F-adobe-times-bold-r-normal--18*   line #!EF . This value is attached to the output 
 #!F-adobe-times-bold-r-normal--18*   tube #!EF as an attribute called "Tube diameter," which can 
be extracted with the Attribute module. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   
ngon #!EF #!EF #!I50 #!N specifies the number of sides of 
the cross-sectional polygon of the tube. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*

Explorer has no effect. #!I0 #!N #!N #!N #!N Components #!N 
#!N Creates new "positions," "connections," and "normals" components. All other components 
are propagated to the output. #!N #!N Example Visual Programs #!CForestGreen
