How to get the "Part_Number" with FeatureScript?

sebastian_glanzner

Hello Everyone,

I need to name my configurations parts automatically. 
The "Part_Name" should be "Part_Number" + "Part_Description"
The reason is when I export the part as a STEP-File it should contain the Number and Description in the File Name.

I managed to automatically create the "Part_Description", but I can't request the actual "Part_Number".
The number is assigned with Configured Part Properties. But I only get "PART_NUMBER" and not the actual number



Does anyone know a solution? Thanks in advance!

FeatureScript 782;

import(path : "onshape/std/geometry.fs", version : "782.0");

annotation { "Feature Type Name" : "Set Name" }

export const setName = defineFeature(function(context is Context, id is Id, definition is map)

    precondition

    {

        annotation { "Name" : "Part", "Filter" : EntityType.BODY, "MaxNumberOfPicks" : 1 }

        definition.myPart is Query;

        annotation { "Name" : "Prefix" }

        definition.prefix is string;

        annotation { "Name" : "Segment 1" }

        definition.segment1 is string;

        annotation { "Name" : "Segment 2" }

        definition.segment2 is string;

        annotation { "Name" : "Segment 3" }

        definition.segment3 is string;

    }

    {

        var partDescription is string = definition.prefix;

        for (var i = 1; i <= 3; i += 1)

        {

            partDescription ~= toString(" ");

            partDescription ~= toString(definition["segment" ~ i]);

        }

        setProperty(context, {

                    "entities" : definition.myPart,

                    "propertyType" : PropertyType.DESCRIPTION,

                    "value" : partDescription

                });

        var partNumber is string = PropertyType.PART_NUMBER;

        var partName is string = partNumber;

        partName ~= toString(" ");

        partName ~= toString(partDescription);

        setProperty(context, {

                    "entities" : definition.myPart,

                    "propertyType" : PropertyType.NAME,

                    "value" : partName

                });

    });

@sebastian_egner Unfortunately, part properties like the part number cannot be gotten from FeatureScript.

Conceptually, part properties are applied by several sources. The FeatureScript properties are applied first (during regeneration). Then, on the fully created parts, properties set through the properties dialog are applied. Finally, properties in the "Configured Part Properties" table are applied to specific configurations.

This means that the "context" passed into your feature is in a rolled back state which does not have the part properties.

For your case I see two possibilities:

1. If you need this done programmatically right now, the right solution is the Onshape API. You can create a private app which will use the "Get Part Metadata" endpoint to get the part number and descriptions, and use the "Update Metadata" endpoint to set the part number based on that.
   
   
2. You can submit an improvement request for a non-programming way to set part properties based on other part properties in a Part Studio

Let me know if you have further questions!

@kevin_o_toole_1 Thanks for the explanations! The suggested workaround with the API sounds interesting!

Set a pair of text variables in part studio and configure them for the values of desired part number and part description. then use some renaming feature, which would set values of variables to the corresponding properties and the value of #partNumber~#partDescription to the part name property.
Or combine all this in one feature which should have tho configured fields for part number and part descr. and then evaluate part name internally and assign it to the corresponding property. Sounds bulky but this is the only way of such automation which works on part studio level.

@konstantin_shiriazdanov Yeah, that sounds like another good solution, where everything is set via FeatureScript!

@sebastian_glanzner If you go that route, make sure to delete your Configured Part Properties table, since the values in that table will override anything set with FeatureScript.

You can verify the property values are being set by switching to a configuration, right clicking a part in the parts list, and selecting properties. All the part properties will be listed there. However, be sure to be careful in that dialog – if you change property values through the dialog and save the changes, those values will be permanently set, and as I mentioned above, they will override any values set in FeatureScript. Unlike configured part properties, there is currently no way to undo this. You can change the value to something else, but right now, the only way to completely unset those values is to contact Onshape support.
