Generate Featurescript from viewer

arpit_agarwal087

Is it possible to generate feature script after creating model using onshape viewer? 

EvanReese

do you mean using the "Show code" selection? If so, then not exactly. Maybe you're interested in creating a feature that instantiates configurations of a certain Part Studio? Or maybe I'm way off. Will you clarify?

I am not sure I know what is "Show code" selection. I have a document which I created using onshape web viewer. I want to obtain the code/instruction which could generate the same document. I want to subsequently reference this code to create a python code or a Feature script to generate the similar documents. 
Let me know this explanation is better.

There's no way to grab featurescript code to create a viewer.

You need to have an OS account, a server, and api keys. Then you make a call to OS (API) and extract the gltf data. Most people use three.js which now has a gtlf importer and you spin a OS model on your web-site.

At this point, you've never used featurescript.

If you right click on the part studio tab, there's a menu item called "show code". This shows the commands used to create all the parts in a part studio. The featurescript code is automatically generated, and with sketches, it's especially hard to follow.

Here's a really simple part studio with one sketch and one extrude.



Here's the code:

FeatureScript 1993;
import(path : "onshape/std/geometry.fs", version : "1993.0");

annotation { "Default Units" : ["cubicMillimeter", "degree", "degreePerSecond", "footPoundForce", "inchPerSecondSquared", "inchPound", "kilogram", "millimeter", "poundForce", "poundPerSquareInch", "second", "squareMillimeter"] }
export function main()
{
    return build({});
}

export function build()
{
    return buildPrivate({});
}

export function build(configuration is map)
{
    return buildPrivate(configuration);
}

const buildPrivate = definePartStudio(function(context is Context, configuration is map, lookup is function)
    precondition
    {
    }
    {
        const id is Id = newId();
        annotation { 'unused' : true }
        var features = {};
        features.FttZ42IO6TvvBJH_0 = function(id)
            {
                annotation { 'unused' : true }
                var features = features;
                if (true)
                {

The extrude has every single option spelled out, even though if you were hand generating a function to do this, you would only call out the options which are not the defaults.

Thanks @S1mon . This is exactly what I was looking for.
