Extrude function from standard library - offset parameters

mathias_millet

Hello,

I have tried to use the extrude function from https://cad.onshape.com/FsDoc/library.html#extrude-Context-Id-map , but it seems there are some issues with offset parameters. I have tried using the parameters described in the doc, but the offset was not taken into account.

I managed to get offset with the following parameters:

```

        extrude(
            context,
            id + "keycap",
            {
                "entities" : definition.face,
                "depth": 10 * millimeter,
                "startOffset": true,
                "startOffsetDistance": 6 * millimeter,
                "startOffsetBound": StartOffsetType.BLIND,
                "startOffsetOppositeDirection": false,
                "operationType": NewBodyOperationType.NEW,
        });

```

In all cases, it is better to construct such features with opExtrude then opBoolean. In the 8+ years I have been writing custom features, I have never used the extrude function. Not saying you shouldn't, but by the time you've worked this problem out, you could have done it at a "lower" level using the "op..." functions.

Thanks for the feedback. I also wanted to add some draft, so using `extrude` felt simpler. But yes I'll try to use lower level functions next time.
