Problem Statement:

With a partner, you will recreate your ghost clip using Solidworks.  You and your partner MUST have identical files that you create by collaborating on each step, one at a time.

Assembly/construction instructions section:

Set up 

1. Make a constraint box that is centered off the origin with construction lines that are 13 cm tall and 6 cm wide 
2. Make the basic constructions 
   1.  A midpoint line vertical and a midpoint line horizontally
   2. Add a horizontal construction line 4 cm up from the bottom from edge to edge (we will call this line b)
   3. Add a horizontal construction line 6.5cm up from bottom from edge to edge (we will call this line c)
   4. Add a horizontal construction line 8.4cm from the bottom from edge to edge (we will call this line d)
   5.  Add a horizontal construction line 10.2cm from the bottom from edge to edge (we will call this line e)
   6. Add a horizontal construction line 1 cm down from the top from edge to edge (we will call this line f)
   7. Add a horizontal construction 1 cm up from the bottom from edge to edge (we will call this line g)

Triangles

1. from construction line f  draw an equilateral triangle that has a 1 cm base along that construction line and two 1 cm legs
2. Make a linear pattern of the triangle geometry that consists of 6 triangles in total along the top of the construction line f 

Semi circles

1. From the bottom left of construction line g make a point on the left corner of that line
2. Then make a point 2 cm away from that point (the corner) still on construction line g
3.  Measure 1 cm down from construction line h from the middle of the two 2 cm points and add a point there.
   1. This point should be on bottom of the construction box 
4.  Make a linear pattern which consists of a total of three semi-circles along the construction line g.

Eyes    

1. Referencing off of  construction line e, go 1.7 cm from the left of the box and make a circle with a diameter of 1 cm
2. Then mirror the eyes to the other side of the design off of the vertical construction

Mouth

1. Semicircle part
   1. Off of construction line c go 1.2 cm from either side of the box and make a point with the arc tool. 
   2. Reference off the vertical construction line and make a point 2.2 cm (that is in middle/ 3 cm from the sides of the box) from the bottom of the construction box along the vertical construction line
2. The other part of the mouth
   1. From the tips (points at the top of the semicircle) of the semicircle make two 4 cm long lines vertically on both sides of the semicircle.  
   2. Offset the semicircle and the lines inwards 0.6 cm and select cap ends with arcs in the parameters  

Back up Plan for top arcs on mouth

1. Arcs at the top of the mouth
   1. Using the two lines on each side of the mouth. Go to the top of the lines and make two semicircles on each side.
   2. This should be 0.3 cms higher than the lines touching construction line e

Design Choices:

Before we began the design, we started by creating a sketch of the ghost tool on centimeter graph paper. We then recreated the constraint box onto the program and added all construction lines that we had labeled on our sketch. 

When creating our constraint box we used the center rectangle tool and then selected the origin. This allowed our constraint box to be perfectly centered! Later we followed our instructions and made the triangles, the semi-circles, the eyes and the mouth. We then followed that up by making two lines one which connected construction line f to construction line g on one side and another line that connected the two construction lines on the other side. We added these as they needed to be existent in the actual outcome of the design and construction lines wouldn't be succesful in acheieving that. 

Using the point tool

While creating our design we found that using the point tool to make references for the semicircle of the mouth would be easier in constructing the shape. We found this tool to helpfull in guiding us on exactly where we needed to select to get our arcs to match the described instructions. Therefore we selected the point tool and made points on construction line b and then used smart dimension to get the points exactly where we needed them to be. 

From the left side of construction line b to the left most point we added a smart dimension that got them to be 1.20 cm apart (as was listed in the instructions) 

Similarly from the right side of construction line b to the right most point we added a smart dimension that got them to be 1.20 cm apart

For the last point we dimension that to be 2.20 cm from the bottom of very bottom of the design 

From here we followed the instructions for the rest of the mouth and then used the offset tool to offset the mouth 0.60 cm inwards

Final outcome:

Defining triangles and semicircles

After completing our design using instructions that we had created, we had encountered a slight problem where some of our triangles and semi circles weren’t defined. 

Semi-circles

To fix this problem we first started with trying to define the semicircles. We tried adding a diameter on all of them or adding the 2.00 cm dimension on the undefined semicircle but all of this ended up over defining the sketch. Instead we got rid of the linear sketch pattern on our semicircles and made sure that the first semicircle was fully defined before adding the linear sketch pattern. This meant that we had to add our dimensions (such as the 1.00 cm diameter and the 2.00 cm distance) and our relations (the coincident points and the tangent relation) applied to the semi-circle before we moved on to create the linear sketch pattern. 

Procedure for defining the triangles

The similar process was followed for the triangles. We got rid of all linear sketches and made sure the initial triangle had defined features before reading the linear sketch pattern. 

However the procedure differed a little bit for the triangles as we had to get rid of some relations. After we got rid of the linear sketch, we took out the equal relation between the legs and we got rid of the coincident points and re-added them only on the bottom corners of the triangle. After removing the equal relations between the legs, we manually added a 1.00 cm smart dimension to all three legs, followed by applying a horizontal relation to the bottom horizontal leg of the triangle. After adding these relations and smart dimensions we re-added the linear sketch pattern to get a fully defined sketch. 

Final Changes

Lastly when comparing our design with a hardcopy of the ghost we decided that we wanted the eyes to be a bit bigger in our design so we changed the diameter of the circles to be 1.10 cm

While comparing our design we also realized that construction line f was a bit more lower from the top of the design than we needed. Therefore we changed the distance between the top of the constraint box to the construction line to be 0.87 cm
