Looking at Tutorial 2.3
Looking at the sketch tools, during profiling,
you can make straight lines of known length and
direction by tabbing between fields in the
boxes above You can make arcs by clicking one of
the circle ICONS and dragging the end point or
tabbing to the radius entering the value and
dragging to an end point
17
Or maybe you can drag the endpoints around
(like me)
When I tried to follow her instructions using the
Sketch Tools Data Fields (which are geometrically
live) I GOT INTO TROUBLE! But it is easy if
you use the tab key to move between fields!
18
Tools toolbar was hidden when I started!

Right Clicking Sketch 2 Then Click Sketch2.object
20
Easy to repair and Back!
21
Elongated Hole was Easy Just Count the
Grid-squares!
If grid is set right --OR-- make the shape that
you want and constraint the distance between the
end arc centers!
22
Over Constrained In Height!
Magenta (like Red) is Bad Over Constained!

Clicking Reference in Definition Box
Iso-Constrains the Feature
Green is Good!
