Working With Orthographic Projections and Basic Isometrics

Isometrics is a drawing system that allows an artist to quickly and accurately draw an object without using perspective. Short on time? Use Envato Market’s Isometric Generators to quickly create awesome graphics.

Orthographics

3D modelers use orthographic projections to accurately create an object in a 3D application. Using orthographics, an Illustrator can easily draw a three-dimensional object from any angle and in perspective. There are no vanishing points or horizon lines, so an object will look the same no matter where you place it.

1. How to Draw Isometrics

How do you draw in isometric? The simplest way to begin is to create an isometric grid in Adobe Illustrator, which will allow us to move on to the meat of the challenge with some basic line-drawing skills.

Step 2

You can draw a 30 inch line on a 30 degree angle with your computer’s line tool.

Step 3

To cross the page, copy the line 1 inch to the left while holding the Alt and Right Arrow keys, then copy it back the same amount of space as before.

Step 4

You can either repeat Step 3 with a 150 degree line from right to left, or select all of the lines and double-click on the Mirror Tool to mirror a copy of the lines horizontally.

Step 5

How do you make an isometric grid? Turn your grid lines into guides with Command A and Command 5 or View > Make Guides s, then save the file as an iso grid template to use whenever you want to work in isometric on a regular grid.

Step 7

Line up your four corners with a square on the grid with your Direct Selection Tool (white arrow).

Step 8

Create the left and right sides of the cube with your Pen Tool and the same method as described above. Quickly block out a four-cornered shape, then move the corners into place with the Direct Selection Tool. When building shapes on an isometric grid, it’s a good idea to start thinking of your objects in planes: top, left side, right side.

Step 9

You now have an isometric cube that you can start making copies of and quickly begin building larger shapes with. You can scale the cube up or down and build with it.

2. How to Incorporate Orthographics

We can incorporate the orthographics discussed earlier now that you know the fundamentals of building a cube on an isometric grid.

Step 1

Create a simple orthographic with a scale that matches your grid.

Step 2

Create the left side first, by roughing out the shape with the Pen Tool and counting grid squares, then lining up the points with the Direct Selection Tool.

Step 3

Count out grid squares, rough out the shape with the Pen Tool, and clean up with the Direct Selection Tool to create the front of the shape.

Step 4

Complete the top. By this point, I’m sure you’ve encountered parts of the shape that don’t just sit on their respective plane; this is where being able to read and interpret the orthographics is critical; otherwise, you’ll end up with a set of orthographics distorted into three planes.

Conclusion

Draw the object from various angles and orientations using the same orthographics; become very comfortable building basic shapes on an orthographic grid; this will come in handy once you start working on more complex objects.

What are the methods for drawing isometric views?

Isometric projection is an axonometric projection in which the three coordinate axes appear equally foreshortened and the angle between any two of them is 120 degrees. It is used to visually represent three-dimensional objects in two dimensions in technical and engineering drawings.

What is orthographic and isometric drawing?

Orthographic, or plan view drawings, represent an object in a two-dimensional fashion by showing each surface of the object in its actual shape. Isometric, or pictorial drawings, represent an object in a three-dimensional fashion by showing three surfaces of the object in one drawing.

What are the 3 views of isometric drawing?

They usually show an object from three different perspectives (usually the front, top, and back).

What are the examples of isometric drawing?

Solution: An example of isometric projection is a technical drawing of a house or building, which is a two-dimensional representation for viewing a three-dimensional object with the three primary lines, all of which are equally tilted away from the viewer.

What is an isometric scale?

n. A radiopaque strip of metal calibrated in centimeters that is placed between the buttocks of a person being x-rayed and used to measure the pelvis’ anteroposterior diameters.

What is meant by isometric view?

In computer graphics, an isometric view is a rendering of a 3D object that eliminates the distortion of shape caused by true perspective; all lines on each axis are parallel to each other and do not converge in isometric views.

What are the limits of isometric drawing?

Isometric Projection’s Drawbacks:

  • It creates a distorted appearance due to a lack of foreshortening. It is more useful for rectangular than curved shapes. It distorts shape and depth. It only provides a 2D view instead of the real one.

Is isometric drawing 2D or 3D?

An isometric drawing is a two-dimensional representation of a three-dimensional object, room, building, or design. Unlike other types of three-dimensional representations, the final image of an isometric drawing is not distorted because the foreshortening of the axes is equal.

What is isometric drawing used for?

Isometric drawings, also known as isometric projections, are a good way of showing measurements and how components fit together on a 2D page. Unlike perspective drawings, they don’t get smaller as the lines go into the distance.

What is difference between isometric view and isometric projection?

What is the difference between an isometric drawing and an isometric projection? Now draw perpendicular offsets from 45u00b0 to 30u00b0 to represent the isometric scale; all dimensions in the isometric drawing are actual, whereas the isometric scale is to be used in the isometric projection.

What is difference between orthographic and isometric projection?

Isometric: a method of representing three-dimensional objects on a flat surface using a drawing that shows three planes of the object; orthographic: a method of representing a three-dimensional object using multiple views from different planes.

What are the six orthographic views?

Six sides of the box become projection planes, showing the six views u2013 front, top, left, right, bottom, and rear u2013 when the object’s surfaces are parallel to the sides of the box.
