Creating sketch geometry
Task 1.
Extrude the dimensioned profile of the crane hook for a distance of 10mm (be careful, this is
really a tangency problem). Name all of the sketch tools you have used while creating sketch
geometry (show some annotated pictures as an evidence of using some of the sketch tools)

Circle - centre point - Almost every dimension on this design was created by
trimming circles after constraining them.
Guidelines - Used to give me a perspective on the design so that it could be created
with the correct angles.
Lines - The only other drawing tool that was used to create the centerpiece of the
hook.
Constraint, coincident and tangent - These constraints allowed me to connect the
circles before trimming and forces lines created to pass through a centre point
without a change in length.
Dimension - Gives me a measurement of the selected parts, includes length and
and angle.
Extrude - Change the width of the hook to the required 10mm.

Task 2.
Create a part model of the single arm that has a thickness of 15mm. Name all of the sketch
tools you have used while creating sketch geometry (show some annotated pictures as an
evidence of using some of the sketch tools)
