Are you frustrated that you can never seem to create a sketch quickly? Do you have trouble with sketches that fail? Does your model fail to update the way you think it should when you modify a dimension? If you answered yes to any of these questions, then follow the five hints below to create a robust sketch.
Tip #1: Keep It Simple!
The best advice for anyone who has trouble in Sketcher is to keep the sketch simple. Don’t try and make a single sketch that encompasses the entire model shape with all cuts and rounded or chamfered edges. Rather, create multiple sketches that are simple, with fewer entities. Fewer entities are easier to control when you start making design changes.
