The option
bool_type works with
sweep_to_body to specify what should be done with the pieces of the profile that were removed during the sweep. This specifies how the selective Booleans are used within sweeping.
|
|
|
LIMIT
|
creates a body which is the result of the sweep up to the location of the intersection between the sweep and the fixed body. This the default setting.
|
|
|
UNITE
|
creates one body out of the fixed body and the result of the sweep up to the location of the intersection between the sweep and the fixed body.
|
|
|
INTERSECT
|
creates one or more pieces resulting from the intersection of the fixed body with the swept body.
|
|
|
SUBTRACT
|
modifies the fixed body by removing material equivalent to the swept body.
|
|
|
KEEP_BOTH
|
creates a body equivalent to the limit type without deleting the original body.
|
|
|
bool_type returns the created body, which is the result of the sweep up to the location of the intersection between the sweep and the fixed body, without deleting the fixed body.
bool_type also controls the numbering on the cells of the tool body and the blank body. The number of cells can affect the results of a defined
keep_law.

Figure 1-9 illustrates the results of defining the bool_type as "limit". What was thrown away in Figure 1-8, is precisely what is kept here.
