Many titles include excellent exercises to teach or learn Autodesk products. You can purchase courseware from the Autodesk eStore on a number of products and topics. The proceeding is an excerpt from the Autodesk Official Training Courseware "AOTC" for AutoCAD and AutoCAD LT 2007. Right-click and select Close on the shortcut menu. The selected line segments are joined together.ģ. Select the other lines to join to the source line and press ENTER. The following steps give an overview of converting an arc to a circle using Join.ģ. Procedure: Converting an Arc to a Circle with the Join Command The following steps give an overview of joining lines using Join. Procedure: Joining Lines with the Join Command The source arc is extended counterclockwise to meet the other arc.
In the following image, the source arc is selected at point (1) while the other arc is selected at point (2). When you join arcs or elliptical arcs together, the source object is always extended to the other objects in a counterclockwise direction.

Ok, now we can get into how to actually draw in isometric. And as the info-graphics style becomes very popular in magazines and newspapers you see isometrics being used more and more by artist with no technical illustration background. The use of isometrics in early videogames has spawned a whole subculture of isometric pixel artists. But isometrics are the only one of these systems to make the jump from the technical illustrators toolbox to a useful skill for all graphic artists. There are many other systems that don’t require vanishing points or horizon lines and give you similar benefits. This is a very powerful tool for speeding up workflow. But you would only have to draw one screw and then copy it as many times as needed. For example you could have an assembly drawing with one hundred screws in it.
This is very important because you only ever have to drawn an object once. An object will be the same anywhere on your page.
There are no vanishing points and no horizon lines. The huge upside to drawing in isometric especially using illustrator is that once you have created an object it will look exactly the same anywhere you place it. This is one of the factors that give isometrics their specific look. If you are going to be working in isometric there is a certain amount of distortion that comes with the territory. This is more noticeable when an isometric cube is sitting next to a perspective cube. Often the first impression of an isometric is that it looks “off”. Typically an orthographic will have the top, side and front views of an object drawn together with some kind of scale. 3D modelers often use orthographics to accurately create an object in a 3D application.Īn orthographic is one way to describe a three dimensional object in two-dimensional space. Using a set of orthographics an illustrator can easily draw the three-dimensional object from any angle and in perspective, isometric or any number of other drawing systems. Orthographics are also called engineering drawings or plan views. Orthographic projections are a way of describing what an object looks like from several different views. I’m going to begin by talking about a system that is commonly used with isometrics. I will go into more depth about isometrics later in this tutorial. Isometric projections are a system of drawing that allows an artist to quickly and accurately draw an object without using perspective.
