opBoolean FS Question

papawo

Can I do opBoolean without user selecting the "targets"?

konstantin_shiriazdanov

if you want to boolean with every solid body of part studio then use
"targets":qBodyType(qEverything(EntityType.BODY), BodyType.SOLID)

konstantin_shiriazdanov

since you want to union opBoolean should have only "tools" and "operationType" filelds in this case -

}]"tools": qUnion[{qCreatedBy(), <code>qBodyType(qEverything(EntityType.BODY), BodyType.SOLID)

sorry, my fault - round brackets for qUnion() and square brackets for argument list
qUnion([qCreatedBy(), qBodyType(qEverything(EntityType.BODY), BodyType.SOLID)])

papawo

thank you for your explanation. it works now.
howabout instead of qUnion , i will use qSubtraction. do i have to use targets?

konstantin_shiriazdanov

if you want boolean operation of subtraction type you would have
{"tools": qCreatedBy(),
"targets": qBodyType(qEverything(EntityType.BODY), BodyType.SOLID),
"operationType": BooleanOperationType.SUBTRACTION}

@konstantin_shiriazdanov --i tried the code below but I get an error saying "cannot subtract from it self". can somebody explain pls.

konstantin_shiriazdanov

it possibly means that targets contains the body created by sweep among other. so in this case
"targets": qSubtraction( qBodyType(qEverything(EntityType.BODY), BodyType.SOLID), qCreatedBy(id+"sweep", EntityType.BODY))

papawo

it works now! thanks. i get your explanation about the sweep.
in qsubtraction (query1,query2)
by doing this query, it separate the 2 bodies so i can subtract it?
while the previous code , query all the bodies including the body created by sweep hence cannot subtract to itself?
am i understanding this correctly?

yes, looks like this is what happens inside boolean
