For (var i = .. Sketch and Plane and Circular pattern

Fda · August 2019

How could you create a with a "for (var i = ...." a Sketch in each plane.

And how Extrude each Sketch.

Please could you give a complete example with a code, perhaps more users will help you with the operation of "opPattern".

opPattern documentation:
https://cad.onshape.com/FsDoc/library.html#opPattern-Context-Id-map

Just typing this up directly on the forum, so there may be some slight typos, but the general idea is:

const lineToRotateAround = line(WORLD_ORIGIN, Z_DIRECTION);
const angleIncrement = (360 * degree) / definition.count;

var transforms = [];
var instanceNames = [];
for (var i = 1; i < definition.count; i += 1) // Iterate from 1 -> (definition.count - 1) because we have already created the base (0) instance
{
    const currAngle = i * angleIncrement;
    const currTransform = rotationAround(lineToRotateAround, i * angleIncrement);
    // Append the currTransform to the transforms list
    transforms = append(transforms, currTransform);
    // instance names don't matter, they just need to be unique strings
    instanceNames = append(instanceNames, toString(i));
}

const patternId = id + "pattern";
opPattern(context, patternId, {
    "entities" : qCreatedBy(originExtrudeId, EntityType.BODY),
    "transforms" : transforms,
    "instanceNames" : instanceNames
});

const booleanId = id + "boolean"; 
opBoolean(context, booleanId, {
    "tools" : qUnion([qCreatedBy(originalExtrudeId, EntityType.BODY), qCreatedBy(patternId, EntityType.BODY)]),

@fermin_fermin_1
You should use var <b>originExtrudeId</b> = id + "extrude1";
where you had var originExtrudeId = qCreatedBy(id + "extrude1", EntityType.FACE);// originExtrudeId ???????

and leave the rest of the code the same.

Jake_Rosenfeld · August 2019

@fermin_fermin_1

The reason it is saying "variable originalExtrudeId not found" is because you are trying to use the variable "originalExtrudeId", and earlier you declared it as "var originExtrudeId = ...". These two names aren't the same.

Otherwise, @MBartlett21 is correct:

const originalExtrudeId = id + "extrude";
opExtrude(context, originalExtrudeId, {
    ...
});

...

const patternId = id + "pattern";
opPattern(context, patternId, {
    "entities" : qCreatedBy(originalExtrudeId, EntityType.BODY)
});

@Jake_Rosenfeld
That is exactly what I didn't notice.
I thought that his feature was failing because it would have been qCreatedBy(qCreatedBy(id + "extrude", EntityType.FACE), EntityType.BODY)
