Offset is a frequently used command which helps us create graphics of the same kind such as concentric circles, parallel lines and so on. This post introduces the basics of Offset command by drawing the section of axle hole.

How to use Object Snap in CAD?

Drawing with coordinates and grids ensures accuracy. But sometimes we’ll need some feature points of given graphics in the drawing. Coordinates of those feature points such as endpoint, midpoint, intersection point are unknown, nor are they on the grid points, then how can we locate those points? Don’t worry, with the Object Snap in CAD, we can easily locate to those feature points, it’s a commonly used drawing tool and therefore it’s very important to know how to set and use this tool, especially for beginners.

How to draw circles with GstarCAD

Drawing circle is a basic operation in CAD designing just like drawing lines. The parameters for circles are simple yet different from drawing lines. The following are some common methods for drawing circles.

How to understand the Command Line

Understanding the Command Line of CAD is important and it’ll help us improve efficiency and save our time.

There are prompts in the Command Line every time we execute a command. Some prompts are simple while others are relatively complex, but they all have the same format. Let me explain this in detail.

What is Polar Snap Tracking in CAD and how to use it?

The dimensions we see in most drawings are about angles and length, few of us would dimension coordinates. When drawing, we tend to use Object Snap or just enter the length and when the lines of graphic objects are orthogonal, we can just use ORTHO. But what if there is a fixed or regular angle, such as 30 degrees, 45 degrees, 60 degrees. That’s what Polar tracking used for.

Operations and concepts about CAD blocks

In our daily drawing with CAD, we usually need to insert some special characters into the drawing and therefore blocks and block attributes are needed to complete the drawing. A good command of blocks and block attributes can improve the efficiency of drawing as well as the quality of the drawing and can be important in completing complex drawings.

Attribute Increment

Command helps to specify attribute of block with incremental value, and to modify attribute value of blocks according to the sort method. This command can increase block attribute value that contains a number or letter.
