Export the geometry of a drawing

fredrik_tärnell

Hi,

Found a few thread discussing wireframe and on in particular that created a FS to do that 
https://forum.onshape.com/discussion/5437/wires-from-edges-suggestions

It does not seem to work for more complex parts/objects.

What I really want it to "produce and object" like what gets during a drawing creation. But as an object I can export. Would that be possible? But I guess I would need access to the actual geometry rather than the exported faces, right?

This code will do it. Create a Feature Studio, paste this in and press commit. The feature will then be available in your Part Studio.

annotation { "Feature Type Name" : "Wireframe Edges" }
export const wireframe = defineFeature(function(context is Context, id is Id, definition is map)
    precondition
    {
        annotation { "Name" : "Parts", "Filter" : EntityType.BODY }
        definition.parts is Query;

        annotation { "Name" : "Delete parts" }
        definition.delete is boolean;
    }
    {
        var edges = qOwnedByBody(definition.parts, EntityType.EDGE);

        for (var i = 0; i < size(evaluateQuery(context, edges)); i += 1)
        {
            opExtractWires(context, id + ("opExtractWires" ~ i), {
                        "edges" : qNthElement(edges, i) });
        }

        if (definition.delete)
        {
            opDeleteBodies(context, id + "deleteBodies", {
                        "entities" : definition.parts });
        }
    });

You can then export the wireframe geometry using STEP by right-clicking the Part Studio tab at the bottom and selecting Export.
