Creating Assemblies

The latest assignments in my 3D modeling class were assemblies, where I drew parts, then them put them together to make objects. There were two drawings and a tutorial. Though the tutorial took a while, it was fun to take new parts and put them together. However, I messed up at least one thing about every part, but I ended up fixing most of the problems. The two assemblies are below.

The Section 5 Test

Since the last post was the section 5 test. The test was on a drawing from the book, to create the 3D part, make it into a 2D orthographic view, and then fully annotate it. The task was simple, with few problems. The hardest part was probably tolerancing the two holes in the back of the figure. The drawings are shown below:

Getting More Intricate

This Section focused on more advanced drawings, starting with the hairdryer. After a few more 3D sketches, I had to start turning them in to fully annotated sketches. I had to draw new parts for some, but others were based on older drawings. The most challenging one would have to be the last, where I had to make a lot of different views for the hairdryer.

Now that the introductions are through...

This past week, I have been using the inventor program to draw 3D objects and materials. The unit taught the basics of how to draw things in inventor, starting with a sketch, giving it depth, and then shaping it to look the way it should. I also, at times, had to label an objects on what their size, volume, center of gravity, and material were, which wasn't hard due to the fact that the information is just three clicks away. However, I found the tutorials a bit tedious, given the fact that I prefer to draw things in my own style rather than follow a step-by-step example. But as of now, I am fully aquainted with Autodesk Inventor, and ready to draw more.

This is my lattest drawing in Inventor as of this post.

The End of the Year

Well, the semester is almost over. In this blog post, I have included a two point perspective from the pictorals unit. It's a shed that I drew and traced on velum, and it took me a while to scan it into the computer. The other one is a drawing I've alredy completed once, but I retraced it using a method called inking. Needless to say, it looks cool.

Section 8

Section 8 in Engineering Graphics was about developments and making them into 3D objects. It was fun, but challenging to see how the distances related. I had to draw the objects inside out, so that put another twist on things. Overall, I made it through will reletively good objects. The hardest part was making the tape look good and not all over the place. Some examples are below.

Unit 6

        This unit was one of my favorites. It was on pictorals, including isometrics, obliques, and perspective views. My favorite drawings were the isometrics because they are 3D representations in a 2D form. Obliques are fun to draw too, but instead of drawing three distorted side views, they show the normal front view, and then the object moves back at a 30 or 60 degree angle. Perspective views show an object that has the appearence of disappearing into the distance. Examples of isometrics and obliques are shown below:
