I can create 3D models of parts in CAD from sketches or dimensional drawings using graphic geometric & dimensional constraints.
Wheel Rim
I used many tools in Inventer to help me make this wheel. First, I created a circle which was .34' in. then another circle that was .44' in. After making two mre circles that were 1.14' in. and 1.24' in., then I was able to extrude it. Selecting both sets of circles by holding down "Ctrl", I extruded it .57' in., then used the "project geometry" button to extrude the area between the two sets of circles both ways .05' in. Secondly, I chose the newly extruded piece for 2D sketching, then I used the circle tool to create a circle that was .5' in. with the center of the circle fixed in to place at the very top of the bigger circle. After using the "trim" tool to get rid of the top half of the circle of that is unneeded, I clicked on "finsh 2D sketch". Thirdly, I extuded back the new sketch, then I circular patterned the new sketch to where it showed 5 rim-like openings.
Snowflake
First, create a circle that is 4' in. in diameter, then create a smaller circle that is no smaller than 3.5' in. but smaller than 4' in. Secondly, create a smaller circle that is .5' in., then create a bigger circle that is no bigger than .8' in. Thirdly, put a line that disects the area in half between the inside of the outer circles and the outside of the inner circles, after doing this put another line above the one you just made and that is what you make your name on. Fourthly, create your name in block letters on the line that is stated above and make sure that it connected to the line safely for future purposes. Fifthly, after you are done making your name now you need to mirror it over the disecting line, after you mirror it click on "finish 2D sketch". After you extrude your current sketch, you need to circular pattern the design how ever many times you want. After doing this make the hook as shown by creating a new sketch on the face and making a circle that is no bigger than .5' in. and make it connected to the model. Then make another circle right the middle of the bigger one that is no smaller than .35' in. Create lines from the top and bottom of the bigger circle to the original model, then trim the excess circle lines. Finish the sketch and extrude the same amount you did the original model and you're good to go.
