Collaboration Time!!!

Dylan_Stewart · August 2016

Okay Ladies and Gents,

I am wanting to create a dummy proof table, meaning that the user is only going to have certain options to choose from and BAM, they get a modeled table. I've got some of the code and some of the parts but really need the support of the community to finish this off. Yes, I admit, I am wanting to use this as a learning experience but I thought this would be a good idea to start using OnShape and FS to it's potential.

I have the table top already made and I have a separate feature to bring in the legs... While this is fine, it's not %100 what I am after.

Here is the link to the document
https://cad.onshape.com/documents/986d7839f605b08daf5b62c4/w/99657d4a66565336c6f8f2ed/e/37a9ad7c057bbfc7f7a76bb5

Here is the code to create the table top

FeatureScript 392;
import(path : "onshape/std/geometry.fs", version : "392.0");

export enum TableTopSize
{
    annotation {"Name" : "24 inch"}
    ONE,
    annotation {"Name" : "30 inch"}
    TWO,
    annotation {"Name" : "36 inch"}
    THREE,
    annotation {"Name" : "42 inch"}
    FOUR,
}
export function evTableTopSize(value is TableTopSize)
{
    return {
        "ONE" : 24*inch,
        "TWO" : 30*inch,
        "THREE" : 36*inch,
        "FOUR"  : 42*inch
    }[value as string];
}
annotation { "Feature Type Name" : "Table Creator" }
export const myTableCreator = defineFeature(function(context is Context, id is Id, definition is map)
    precondition
    {
        annotation { "Name" : "Table Top Size" }
        definition.tableTopSize is TableTopSize;
        
        
    }
    {
        
        var tableTop = evTableTopSize(definition.tableTopSize);
        var legLoc1 = 4*inch;
        var legLoc2 = tableTop - 4*inch;
        var tableVerticies = [vector(0*inch, 0*inch), vector(0*inch, tableTop), vector(tableTop, tableTop), vector(tableTop, 0*inch)];
        var legLocationVerticies = [vector(legLoc1, legLoc1), vector(legLoc1, legLoc2), vector(legLoc2, legLoc1), vector(legLoc2, legLoc2)];
        var tableSketch = newSketch(context, id + "TableSketch", {
                "sketchPlane" : qCreatedBy(makeId("Top"), EntityType.FACE)
        });
        skLineSegment(tableSketch, "line1", {
                "start" : tableVerticies[0],
                "end" : tableVerticies[1]
        });
        skLineSegment(tableSketch, "line2", {
                "start" : tableVerticies[1],
                "end" : tableVerticies[2]
        });
        skLineSegment(tableSketch, "line3", {
                "start" : tableVerticies[2],
                "end" : tableVerticies[3]
        });
        skLineSegment(tableSketch, "line4", {
                "start" : tableVerticies[3],
                "end" : tableVerticies[0]
        });
        skCircle(tableSketch, "Leg1", {
                "center" : legLocationVerticies[0],
                "radius" : 1 * inch
        });
        skCircle(tableSketch, "Leg2", {
                "center" : legLocationVerticies[1],
                "radius" : 1 * inch
        });
        skCircle(tableSketch, "Leg3", {
                "center" : legLocationVerticies[2],
                "radius" : 1 * inch
        });
        skCircle(tableSketch, "Leg4", {
                "center" : legLocationVerticies[3],
                "radius" : 1 * inch
        });
        skSolve(tableSketch);
        var tableRegion = qSketchRegion(id + "TableSketch");
        extrude(context, id + "extrude1", {
                "entities" : qSketchRegion(id + "TableSketch"),
                "endBound" : BoundingType.BLIND,
                "depth" : 1.5 * inch
        });
    });

And here is what I have to bring in the leg

FeatureScript 392;
import(path : "onshape/std/geometry.fs", version : "392.0");
PART::import(path : "b0ce9ce1e52b3c3c2503487d", version : "2e1edf42723d4d88750dd977");
// PART::import(path : "1c26e00fc778219a6a385f3a", version : "f71775f0a10f7cfd8dbea65b");
// PART::import(path : "c79f1a234a9f7dcf3cd1da1e", version : "60326f3c3ce5854d658b085b");


// export enum LegOptions
// {
//     annotation {"Name": "Round Leg 1"}
//     FpDkrwSQ3HtgoSB_1,
//     annotation {"Name": "Round Leg 2"}
//     FTDZgmKUHISz1PO_0,
//     annotation {"Name": "Round Leg 3"}
//     FhcUhDPPvmJadnm_0
// }
annotation { "Feature Type Name" : "Import Leg" }
export const myFeature = defineFeature(function(context is Context, id is Id, definition is map)
    precondition
    {
        annotation { "Name" : "Point", "Filter" : EntityType.VERTEX, /*"MaxNumberOfPicks" : 1*/ }
        definition.point is Query;

        // annotation { "Name" : "Leg Choice" }
        // definition.legChoice is LegOptions;
        
    }
    {
        var transforms = [];
        var point = definition.point;
        opMergeContexts(context, id + "mergeContexts1", {
                    "contextFrom" : PART::build()
                });
        var importedPart = qCreatedBy(id + "mergeContexts1", EntityType.BODY);
        var location = evVertexPoint(context, { "vertex" : point });
        var origin = vector(0, 0, 0) * inch;
        opTransform(context, id + "transform1", { "bodies" : importedPart, "transform" : transform(location - origin) });
    });

The problem is that I want to eliminate all mouse clicks and be able to toggle between different legs.

Any and all help is appreciated.

Thank you

What if you create parametric table with default tools and use FS to run parameters? I understand that you are using this as example but I would see a lot of potential if it is possible to create 'user interface' and limits for parameters using feature script.

A while back, I was thinking chest of drawers created completely with FS but it needs some serious coding to create slides etc. so I came up with idea to combine FS with parametric model

Dylan_Stewart · August 2016

So you're saying kind of like Inventor with forms? A 'pre-modeled template' so to say? That would work and I would like to see an example of what you are talking about.

I admit, I need to brush up on my coding and maybe even take a few more classes so that I understand everything.
So I will have to apologize up front for the waves of questions I will have throughout this process.

What I lack in knowledge I more than make up for in enthusiasm.

3dcad · August 2016

I have only two problems with FS. 1. I don't know how to code 2. At the moment I don't have enough time to learn.

But I'm very interested in use cases, so I would also like to see an example of what I suggested (if it's possible).

lougallo · August 2016

A good example is in the FS Example doc with the measure. That uses the measure to add more rungs to a ladder (if you wanted to get fancy with the number of legs). It could be brought in like you have it setup in your second script, add that in the first but then insert it derived and then transform it into position

Dylan_Stewart · August 2016

So many thanks to everyone especially @lougallo to make this become a reality.

This is only the beginning and I am looking forward to elaborating and collaborating on this project.

Here is the code to generate a table with only 2 options.

Dylan_Stewart · August 2016

Amazing stuff @lougallo !!

3dcad · August 2016

Link this into webshop and get orders with updated BOM into production - that would be pretty cool..

@lougallo
thanks for this example, I suppose you 'modeled' table top with FS code? Is it possible to do the same so that you have table top in one part studio and you use variables to control the size?

Dylan_Stewart · August 2016

I've inquired on this and I think FS is not capable of doing this (for now)

I get the feeling that it is just around the corner.

3dcad · August 2016

I suppose it could be possible but variables need to be on same part studio where you run 'table script'.. I really like the super clean feature list of that Lou's example though..

Dylan_Stewart · August 2016

@lougallo @ilya_baran @kevin_o_toole_1
can you explain why this will not work if I change the sketchPlane?
from:

var tableSketch = newSketch(context, id + "TableSketch", {
                "sketchPlane" : qCreatedBy(makeId("Top"), EntityType.FACE)
            });

to:

var tableSketch = newSketch(context, id + "TableSketch", {
                "sketchPlane" : qCreatedBy(makeId("Front"), EntityType.FACE)
            });

Dylan_Stewart · August 2016

Okay, so further playing around with this it seems that this particular code is only good for a sketch that is created on the 'Top' plane.

What if a user wanted to use the 'Front' plane?

Further more, if the user wanted to make a symmetric part and place legs on the bottom and plates on the top?

Edit: Also the orientation of the derived/imported part, for example I want the legs to come in rotated 45 degrees.

lougallo · August 2016

You have to remember that when you use a version (linked docs) it is not changable. You can run FS on a model and change things but in the case I had, I had to have the data there... However you could do alterations to it after the fact but I would probably just build the components via FS to start.

Dylan_Stewart · August 2016

@lougallo

I don't want to change the derived part, rather just place it on an exact point and plane (whether its on the top or bottom) and if the base sketch, in this case the table top, if it's on the top, front or right plane and then rotate the legs.

The reason I would like to import parts rather than writing in code is to be able to import complicated parts that would require too much code to write (if it's even possible)

Forgive me if I am misunderstanding something.

Dylan_Stewart · August 2016

I imagine it would rely heavily on the origin of the imported part studio?

        var origin = vector(0, 0, 0) * inch;
        var xaxis = vector(0, 0, 1) * inch;
        var zaxis = vector(1, 0, 0) * inch;
        var skplane = plane(origin, xaxis, zaxis);

This section is still a bit confusing to me... I assume that the understanding of this would point me in the right direction of what I want to accomplish.

NeilCooke · August 2016

Use newSketchOnPlane - you can pass your skplane into it and it's much easier to use.

Dylan_Stewart · August 2016

@NeilCooke I apologize, but I'm not %100 sure what you mean?

I have a FS that creates a rectangle on the 'Front' plane and has circle cut outs that can be either on the right or left.

I have a PS that is not ambidextrous (there for would have to be rotated 180 degrees depending on the side.

Also, my rectangle is extruded symmetrically. So I would like to be able to imported part follow the desired face.

Since we can not control variables from PS through FS, I figured this might be a sort of work around (if at all possible to do the above mentioned)

NeilCooke · August 2016

Sorry I didn't read the whole thread just your bit about not being able to create a sketch on the front plane - I will read and answer later.

Dylan_Stewart · August 2016

@NeilCooke Thank you.

I'm now wondering if the 'opTransform' can be simplified?

opTransform(context, id + "transform1",{
           "bodies" : importedPart,
           "transform" : ??vector(1, 1)??
