Surface from solid

viktor_paile

Hello, here's this noob's question 1:

Is there a way in Onshape, or indeed in FeatureScript, to retrieve (or query for?) the surface of a given solid? Say, get a spherical surface from a given solid sphere?

qOwnedByBody would work for this: 

FeatureScript 1472;
import(path : "onshape/std/geometry.fs", version : "1472.0");

annotation { "Feature Type Name" : "test" }
export const myFeature = defineFeature(function(context is Context, id is Id, definition is map)
    precondition
    {
        annotation { "Name" : "body", "Filter" : EntityType.BODY, "MaxNumberOfPicks" : 1 }
        definition.body is Query;
        
    }
    {
        const faces = qOwnedByBody(definition.body, EntityType.FACE);
        debug(context, faces, DebugColor.RED);
    });

Here is a neat query explorer feature may help you out: https://forum.onshape.com/discussion/14777/query-explorer-feature

Also, if you search the forums for "new custom feature" you will find most of my features. Some of the earlier ones have nice notes for someone starting from scratch.
