Onshape lesson3 Summary(第三課摘要) Let’s take a second to reflect what we learned in this lesson. 1. We learned about the three Boolean operations - Union, Subtract, and Intersect. 2. We learned about linear and circular part patterning. 3. We were introduced to sketch patterning, which patterns sketch entities, not parts. 4. We learned about multi-part design in a single Part Studio. 5. We learned to use the Mirror tool to complete our “half model”.
