Feature script: Circular pattern + Torrodial rotation by steps around secondary axis.

Code by clause on preplexity, I helped .

import(path : "onshape/std/common.fs", version : "2752.0");

// Define custom angle bounds
export const CUSTOM_ANGLE_BOUNDS = {
(degree) : [0, 15, 360] // [min, default, max] in degrees
} as AngleBoundSpec;

export const TOTAL_ANGLE_BOUNDS = {
(degree) : [1, 360, 1080] // [min, default, max] - allows up to 2 full rotations
} as AngleBoundSpec;

annotation { "Feature Type Name" : "Dual Axis Pattern" }
export const dualAxisPattern = defineFeature(function(context is Context, id is Id, definition is map)
precondition
{
annotation { "Name" : "Bodies to pattern", "Filter" : EntityType.BODY }
definition.entities is Query;

    annotation { "Name" : "Circular pattern axis", "Filter" : GeometryType.LINE }
    definition.circularAxis is Query;
    
    annotation { "Name" : "Step rotation axis", "Filter" : GeometryType.LINE }
    definition.stepAxis is Query;
    
    annotation { "Name" : "Number of instances" }
    isInteger(definition.instanceCount, POSITIVE_COUNT_BOUNDS);
    
    annotation { "Name" : "Total rotation around main axis" }
    isAngle(definition.totalRotation, TOTAL_ANGLE_BOUNDS);
    
    annotation { "Name" : "Step angle per instance" }
    isAngle(definition.stepAngle, CUSTOM_ANGLE_BOUNDS);
}
{
    var circularAxisLine = evAxis(context, { "axis" : definition.circularAxis });
    var stepAxisLine = evAxis(context, { "axis" : definition.stepAxis });
    
    // Calculate angle between instances: totalRotation / instanceCount
    var anglePerInstance = definition.totalRotation / definition.instanceCount;
    
    var transforms = [];
    var instanceNames = [];
    
    for (var i = 1; i < definition.instanceCount; i += 1)
    {
        // Step 1: rotate around secondary axis by stepAngle * i
        var stepRotation = rotationAround(stepAxisLine, definition.stepAngle * i);
        
        // Step 2: rotate around main axis by anglePerInstance * i 
        var circularRotation = rotationAround(circularAxisLine, anglePerInstance * i);
        
        // Combine: main rotation AFTER step rotation
        var combinedTransform = circularRotation * stepRotation;
        
        transforms = append(transforms, combinedTransform);
        instanceNames = append(instanceNames, "instance_" ~ i);
    }
    
    if (size(transforms) > 0)
    {
        opPattern(context, id, {
            "entities" : definition.entities,
            "transforms" : transforms,
            "instanceNames" : instanceNames
        });
    }
}

);

Hi @nitai_ierushalmi,
Do you have a specific question or are you just showing off your feature? It's hard to tell from your post.
