Dynamic Editing and Sketcher Functionality
A drag handle is attached to the sketch entity of the feature to allow translation as a rigid body. The handle is constrained to move within the sketch plane, in the directions allowed by the dimension and constraint scheme. The handle appears as a shaded sphere, approximately at the center of the sketch.
When a single sketch-based feature is edited, the sketch dimensions are shown by default, and you can click and drag the sketch entities and vertices to edit them.
When multiple sketch-based features are edited, the sketch dimensions are not shown by default. Click one of the sketches for its dimensions to be shown, then click and drag to edit them. To edit a different sketch, click twice on the intended sketch, and then click and drag to edit it.
