# orthogonal projections… practice ED/EG/MD

It seems like you're referring to terms related to engineering or technical drawings, specifically in the context of orthogonal projections. Let's break down these terms:

1. Orthogonal Projections:

• Orthogonal projections, in the context of technical drawings or engineering graphics, refer to the projection of three-dimensional objects onto two-dimensional planes using perpendicular lines. This is commonly used in creating engineering drawings to represent the true shape and size of objects.
2. ED (Edge View):

• In an orthogonal projection, the Edge View (ED) typically refers to the view of an object as seen from one of its edges. This view helps to represent the shape and features of the object along a specific direction.
3. EG (End View):

• The End View (EG) usually refers to the view of an object as seen from one of its ends. This view provides information about the object's features and dimensions in the direction perpendicular to the edge view.
4. MD (Multiview Drawing):

• A Multiview Drawing (MD) is a drawing that shows an object as it appears in two or more orthogonally projected views. These views typically include the front, top, and side views, providing a comprehensive representation of the object.

Now, let's practice creating an orthogonal projection for an object:

Let's consider a simple rectangular prism (a box) as an example. We'll create front (FV), top (TV), and right side (SV) views:

1. Front View (FV):

• Imagine looking at the front face of the box. Draw the front view by representing the width and height of the box.
2. Top View (TV):

• Imagine looking down at the top face of the box. Draw the top view by representing the length and width of the box.
3. Side View (SV):

• Imagine looking at the right side of the box. Draw the side view by representing the length and height of the box.

Ensure that the relationships between the views are consistent. For example, if the front view shows the width and height, make sure the top and side views also reflect the corresponding dimensions accurately.

Remember, practice is key in mastering technical drawing skills. Feel free to clarify or provide additional details if you have a specific question or if you'd like guidance on a particular aspect of orthogonal projections.
