Splitting Parts Removes Attributes

Cappie_Pomeroy

According to the docs at https://cad.onshape.com/FsDoc/library.html#module-attributes.fs

"Attributes stay with the entity they are defined on, even as the Part Studio changes. An attribute on a face, edge, or body which is split in two will be set with the same name and value on both split pieces."

However, the following feature script.

FeatureScript 1403;
import(path : "onshape/std/geometry.fs", version : "1403.0");
annotation { "Feature Type Name" : "My Feature" }
export const myFeature = defineFeature(function(context is Context, id is Id, definition is map)
precondition
    {
        // Define the parameters of the feature type 
       annotation { "Name" : "My Query", "Filter" : EntityType.BODY, "MaxNumberOfPicks" : 1 }
        definition.myQuery is Query;
    }
    {
        // Define the function's action
        setAttribute(context, {
                "entities" : definition.myQuery,
                "name" : "myName",
                "attribute" : "myValue"
        });
        debug(context, getAttributes(context, {
                "entities" : qEverything(EntityType.BODY),
                "name" : "myName"
        }), DebugColor.BLUE);
        opPlane(context, id + "plane1", {
                "plane" : plane(XY_PLANE.origin, XY_PLANE.normal)
        });
        opSplitPart(context, id + "splitPart1", {
                "targets" : definition.myQuery,
                "tool" : qCreatedBy(id + "plane1", EntityType.BODY)
        });
        debug(context, getAttributes(context, {
                "entities" : qEverything(EntityType.BODY),
                "name" : "myName"
        }), DebugColor.BLUE);
    });

Will log:

debug: [ "myValue" ]
debug: []
  Result: Regeneration complete

What am I missing?  The attribute is being completely removed it doesn't stay on either body after the split let alone both like the docs say.  I hope that I'm doing something wrong or that this is a bug because it would be very useful for me if the attributes stay on both bodies.

Here's a link to a document that shows the issue if that helps at all, be sure to turn on the debug console to the see the logged outputs!

This has been identified as a bug. We have a fix in QA testing now but it may be too late to make it into the next release. The “legacy” way of creating attributes still works if it is an urgent job. 

Cappie_Pomeroy

Oh thanks!  It isn't super urgent we have ways of doing something similar to what this featurescript will eventually accomplish it will just save a lot of time when it works.

Cappie_Pomeroy

Hi, this still doesn't seem to be working.  Are there any updates?  Do I need to do anything besides change the imported FeatureScript version?

It looks like the fix has been reported prematurely. I'll write a bug to make sure it does not get lost. 

George_Anderson

I am seeing the same behavior through an opTransform. I assume this is the same underlying issue, and the bug is still active?

Alex_Kempen

It seems to work fine for me. Maybe there's a bug in your code somewhere?
