Defines the number of calculation passes when a welded design is generated. The option can be set to 1-PASS or 2-PASS. The number of passes affects the coherence of the design caused by radial line
propagation. Propagation occurs where the radial line of one object intersects another . At the point of
intersection a net line is added to the intersected object, therefore generating a coincident point on each
object. If the weld calculation passes are set to 2-PASS the propagation occurs both forwards and
backwards in the order of object generation, guaranteeing coincident joining points generated throughout
the design. Turning the option to 1-PASS is an efficiency measure which may be helpful during the design
process, but should only be used when needed.
Option: Unfold Side
This defines whether the object unfold commands generate a template from the outside of the design or
the inside.
Option: Parallels
In some cases designs with flat sides intersect with their sides parallel to each other. In these cases there
are options on the way the intersection is handled. They can be treated as equal, or the object higher in
the object order can take the priority. Note: This is a rare occasion when the order of the objects in the
design can affect the welded result.
Option: Default Radials
Define the number of radial divisions to use by default in the objects of the design. The radial divisions
apply to the full 360 degrees of the design. In cases where the design has a number of circular and flat
sided sections the number of radial division used is for the section is proportional to its proportion of a full
360 degree sweep. In other words a section with a 90 degree sweep has one quarter of the number
defined in the 'Default Radials' option. Flat sides also have radial divisions although the radial lines are not
visible. The number of lines affect the accuracy of the generated result. A flat side is always treated as
having the equivalent number of divisions as a 90 section.
Option: Termination Level
The termination level is a model generation option.
Triple points are points at which three objects intersect. These points often do not occur at points
coincident with radial or net lines. If this option is enabled then the exact triple point is determined and
included by adding a net line at the point.
Option: Non-Relative Intersections
Intersections normally occurs between connected objects only. If this option is enabled then the
intersection calculation is extended to objects that have no connection. The intersection of the non-connected objects is determined purely by their proximity. There are occasions where two objects are
connected to opposite ends (or just different nodes) of another object, they have no connection but there
is some physical interference between them. In these cases the non-relative intersection options should be
turned on to generate the correct intersection.
When enabling this option it is often necessary to also raise the 'Termination Level' (see earlier), otherwise
intersections will occur beyond the end/termination limits of the object.
Option: Conserve Points
The default welded object generation generates intersection points at all radial and net lines. This occurs
on flat side and result in intersection points that sequentially lie in a straight line. This option causes the
redundant points to be eliminated to leave a single straight line. In other words all inline mid points are
eliminated.
