208 CHAPTER 6 GettinG More froM Your SketcheS

18. Ensure Instant 3D is disabled, then Ctrl+drag any face of the Cut feature, and drop it onto
another flat face. The Ctrl+drag function copies the feature and the sketch, but the external
dimensions and relations become detached.
19. Click Dangle in response to the prompt. This means that you have to reattach some
dangling dimensions rather than re-create them. Edit the newly created sketch, which now
has an error on it.

20. Two of the dimensions that went to external edges now have the olive dangling color.
Select one of the dimensions; a red handle will appear. Drag the red handle and attach it to
a model edge. Do this for both dimensions. The dimensions will update to reflect their
new locations. Exit the sketch and verify that the error flag has disappeared.
21. Select Sketch5. Ctrl+select a flat face on the model other than the one that Sketch5 is on. In
the menu, choose Insert ➢ Derived Sketch. You are now in a sketch editing the
derived sketch.
TIP the sketch is blue, so you should be able to resize it, right? no, it doesn’t work that way for de-
rived sketches. Derived sketches are driven by their parent sketches. You can test this by dragging the
large circle; it repositions the entire sketch as a unit.

22. Dimension the center of the large circle to two perpendicular edges of the model. Move
the sketch over the solid geometry if necessary.
23. Drag the smaller circle and observe that it swivels around the larger circle. Create an angle
dimension between the construction line between the circle centers and one of the model
edges. Notice that the sketch is now fully defined.
24. Exit the sketch and look at the name of the derived sketch in the FeatureManager. The
term Derived appears after the name, and the sketch appears as fully defined.
25. Right-click the sketch and select Underive Sketch. Notice that the sketch is now underde-
fined. The Underive command removes the associative link between the two sketches.
26. Close the file.

Tutorial: Controlling Pictures, Text, Colors, and Styles

This tutorial guides you through some of the miscellaneous functions in sketches. It also shows
you what they are used for and how they are used. Follow these steps to learn how to control
these items:
1. Open a new part using a template with inches as units. Open a sketch on the front plane
and draw a construction line starting from the origin 12 inches down (negative Y), away
from the origin.
