1.6 Practice Problem:
1.6 Practice Problem:
Using SolidWorks to create the 1.6 part matching the provided engineering drawings and dimensions. First I created the back as the base of my part with the boss-extrude feature as well as cutting out the two holes on each side using the cut-extrude feature. Next I extruded the sketch of the middle section using the mid-plane feature and made sure to match angles and parallel lines before cutting out the hole on the end of the extrusion. The final step was to create the step out on both sides which I sketched on the same plane as the last extrusion before using the mid-plane feature to extruded the feature and the fillets for the matching curves. On my original attempt I missed that the bottom of the last extrusion is parallel to the x-axis and not at an angle which made it off a little bit but my final volume was 24030.44 cubic millimeters so only off by 1.56 cubic millimeters.

2.4 Practice Problem:
Using SolidWorks to create the 2.4 part matching the provided engineering drawings and dimensions as well as figuring out missing dimensions. first I started with the base sketch of a circle to extrude 3mm with a radius of 43mm before adding 3 circles about the circle in a circular pattern feature with equal spacing then filleting the corners where the smaller circles meet the big circles. Next I ofset the sketch of the top of the boss-extruded feature to step up the next layer by another 3mm before adding the extruded circles. The final step was to use the boss-extrude feature and extrude 3 circles around the part at the center where the original smaller 3 circles were out 12mm then finally cutting out a hole i the bottom of each extruded circle and a smaller hole all the way through as shown in the pictures to the left.

3.4 Practice Problem:
Using SolidWorks to create the 3.4 part matching the provided engineering drawings and dimensions as well as figuring out missing dimensions. The first step in creating the design for this part was to sketch a center circle to base the center lines and sketch lines from that go about the center of the deign. The next step was creating the outside of the shape by sketching lines with the proper dimentsions before using the mirror and circular sketch pattern to replicate the lines about the circle. After connecting all of the lines and solving for the proper dimensions the final step of the design process was to add the total 36 fillets around the edges of the sketch I used the sketch fillet feature before extruding the entire shap 110mm. Lastly I sketched the 2mm diameter circle in the center of the part to cut a hole through the middle.

4.16 Practice Problem:
Using SolidWorks to create the 4.16 part matching the provided engineering drawings and dimensions as well as figuring out missing dimensions. This part was very simple and the process that I took to create it included creating a block like figure then cutting out the necessary sections to form the object. The first step I took to create the part was to sketch an outline of the shape from the side/front view before using the boss-extrude feature out of a mid-plane 41mm to get the base block. Next I cut out the left side of the shape using the cut-extrude feature 42mm in including the big circle on the side. Next I used the cut-extrude feature to cut out the two circles on the top of both the high and low face of the part using the smart dimension to ensure they are in the proper place. One of the last steps was to use the cut-extrude feature to cut out the square on the bottom of the part that goes all the way through the bottom. Finally I used the chamfer feature to cut the three edges at a 45 degree angle but used trial and error to fin the missing height of the chamfer that was not including in the engineering drawing until it got really close.

5.13 Practice Problem:
Using SolidWorks to create the 5.13 part matching the provided engineering drawings and dimensions as well as figuring out missing dimensions. The first step in creating this part was to sketch a 37.5mm radius circle on the top plane before using the boss-extrude feature to extrude it up 200mm and then cutting out the center hole of a radius of 30mm all the way through. The next step which proved to be the most difficult was creating the angled sketch at first I tried to angle it on the front plane before realizing I could use the reference geometry feature to create an angled plane. After creating the angled plane I sketched the shape on the side adding sketch fillets and boss-extruded it up to the surface of the sphere. Finally I sketched the 4 circles on the side extrusions spaced according to the dimensions before cutting them out using the extrude-cut feature.

6.14 Practice Problem:
Using SolidWorks to create the 6.14 part matching the provided engineering drawings and dimensions as well as figuring out missing dimensions. At first this part seemed difficult but after careful consideration I realized that it isn't that bad. The first step for this part was to create the base sphere by sketching a semi-circle with the desired radius of 25mm before using the swept-boss base feature to rotate it around the center axis creating a sphere. Next I created two planes offset from the top plane both 23mm down and 17mm up before sketching circles on each plane and cutting down the sphere creating two flat faces on both sides. The next step was cutting out the center of the sphere with an offset of 2mm then cutting down a circle 5mm into the sphere, then creating a hexagon shape with an equal radius to the first circle and using the cut-extrude feature to cut it down 15mm, lastly I created a circle sketch with a diameter 9.8mm and cut out that circle all the way through the bottom of the sphere. The final step was to make a 1mm deep and 2mm cut on the side of the sphere by sketching a arc on the right plane before offsetting the line 1mm inwards then using the extend feature to make the line go all the way to the top and the bottom of the sphere before cutting it out 2mm of a mid-plane cut-extrude to both sides.

7.4 Practice Problem:
Using SolidWorks to create the 7.14 part matching the provided engineering drawings and dimensions as well as figuring out missing dimensions. This part was constructed using lots of spheres and revolve features after I identified that it is made of spheres. The first step to create this part was to create a sphere of a 8mm diameter using the revolve boss feature 16.5mm from the origin then cutting a sphere out of the inside of that sphere with a diameter of 6mm. The next step was to create a circle and extrude it with a midplane of 1mm thickness with a radius of 16.5mm in order to use the circular sketch pattern to repeat the spheres around the center of the circle. After using the circular pattern the final step was to cut out everything outside of the 16.5mm circle and inside of the 14.5mm circle. Also I needed to reorder the revolve cut of the smaller sphere so it would apply to all 8 of the spheres.

8.4 Practice Problem:
Using SolidWorks to create the 8.14 part matching the provided engineering drawings and dimensions as well as figuring out missing dimensions using geometry. This part was designed as a carabiner and took multiple difficult steps to complete. The first step to creating this part was creating a sketch of the outline for the carabiner but at the center of the sphere so I had to add 0.15in to each dimension. I created a semi-circle at the bottom then another semi-circle at the top and connected the one side with a line before making it tangent with the curve to create the turns naturally. The next step was to use the sweep-bose-base feature so the circle can follow along the sketch making it 3 dimensional. Finally I sketched the little extrusions on both the top and bottom faces of the carabiner.
