""" name: custom_sketch_objects.py by: Gumyr date: Jan 21st 2023 desc: This example demonstrates the creation of a Playing Card storage box with user generated custom BuildSketch objects. Four new BuildSketch objects are created: Club, Spade, Heart, and Diamond, which are then used to punch holes into the top of the box's lid. license: Copyright 2023 Gumyr Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License.
