I’ve been using Autodesk Inventor for half of my life at this point and it’s a software that I love and know well. I’ve been teaching Inventor to my students for the past several years and I wanted to make some videos outlining how to do various tasks in the program.
I plan on adding an entire set of videos showing tutorials of how to do all of the major things in Inventor so that students can easily learn new skills without my direct intervention.
As mentioned with one and two point perspective drawings, perspective drawing can be challenging. The most challenging of all of these is the 3 point perspective drawing. In the video below I walk through the steps to successful create a three point perspective drawing.
A few things to remember about three point perspective drawings:
- Width lines go back to the left vanishing point
- Height lines go to the bottom (or top) vanishing point
- Depth lines go to the right vanishing point
As with one point perspective drawing, 2 point can be difficult to understand and create. The measurements get even less sure on a two point perspective drawing and, depending on your accuracy, the final view can look very different from the original.
A few things to remember when creating a two point perspective drawing:
- Width is shown by lines going towards the left vanishing point
- Height is shown by vertical lines
- Depth is shown by lines going towards the right vanishing point
Perspective drawing can be one of the more difficult things to do in drafting. It’s tough because, unlike some other pictorial drawings, you do not have actual measurements to go draw with everything. In perspective drawing, there is some guess work. In the video below, I describe how to create a 1 point perspective drawing.
A couple of things to keep in mind:
- Width lines are represented by horizontal lines
- Height lines are vertical lines
- Depth lines go back to the vanishing point
- Front view is exactly the same in a 1 point perspective drawing
In the video below I review the three types of pictorial drawings and the sub-types of drawings to come from them.
Drafting is a type of communication that engineers and manufactures use in order show how an object goes together or what it looks like. There is a specific way that these drawings are made. In general, there are three basic items show in the drawing: front view, right view, and top view. In the video below I show what each of the views communicates and how they are setup on a page.
When you begin to learn drafting, you have to learn about the different types of lines. Line types are extremely important because they are used to communicate different ideas about an object. In the video below we review the three basic types of lines that are necessary to understand when you are beginning to learn about drafting.
Three types of lines
Visible or Object Lines
Dark thick lines that show the outside edges of an object.
Construction Lines
Light lines that are drawn to help place other lines on a drawing. They eventually get erased.
Hidden Lines
Dashed lines that show parts of an object that cannot be seen from the current viewing angle. Hidden lines exist to show engineers and manufactures that there are features on an object that exist but can’t be shown through another means at the current angle.
Graphic communication is something that happens every day without us even realizing it. In the video above we look at graphic communication and how humans have used symbols and other image-based items for thousands of years to transfer their thoughts and feelings to others.
