Beyond this, we move into putting the parts together into assemblies, which helps to make the "pretty pictures" look like something useful. Finally, we use the parts and assemblies to create drawings.
Several basic facts about sketches may be helpful before we start. While a part may have many sketches, only one sketch can be open at a time. This is due in part to the history-based ...
