1. Grouping:

  • Simple and Effective:
    • After lassoing your shapes, immediately press Ctrl+G (or right-click and select "Group"). This turns your selected shapes into a single object.



    • Now, you can move, resize, and rotate the entire group while preserving the relative positions of the individual shapes within it.



    • To edit individual shapes later, right-click the group and select "Ungroup."
