This option allows you to make precise AutoCAD drawings. The default value of this system variable is OFF which keeps the lineweight display off you can change its value to ON to keep lineweight visible in the drawing area. You change the value of this system variable to 1 to make transparency visible or 0 if you want to make it invisible.

When the value of this system variable is set to 2, an overlapping icon and a menu containing a list of overlapping objects appear and you can select the required object from this list. If you set the value of this system variable to 1, only the overlap icon appears not the menu.

You can turn this off by changing the value of this system variable to 0. F6 Dynamic UCS can be activated or deactivated using this function key.

General Commands These are some of the commands which can be frequently used in your drawing workflow to improve your overall efficiency. To count the block it should be visible in the drawing area. When you trim or break this infinite line to a finite length it becomes a simple line geometry.

To modify the type of point created by this command you can use PTYPE command and choose the desired point type from Point Style window.

You can use Line, Polyline or Spline as the object type for making this freehand sketch. To cancel repetition of command press ESC key. To know more about this subcommand refer the related article. This is especially helpful if you want to retain the text of attribute after exploding the block.

You can use this command to even write text aligned to a circle. More about this command can be found in this related article.

After deleting an object if you made many other changes in the drawing and realized that you might need to restore the deleted object then simply type OOPS and press enter. See the animated image shown below for reference. At each point of division, a point geometry will be added on the 2D curve.

It is helpful if you want to break a curve at the point of intersection with other curve or if you want to create a gap by breaking a part of the geometry. TIME Using this command you can find a lot of information about your drawing like the date when the drawing was created and total editing time consumed on the drawing. As an example, you can use quick select to make a selection set containing all circles of the drawing with the radius of a particular value.

LIST Using this command you can find lots of properties of an object like the layer they are on, area, length or radius, perimeter or circumference and a lot more. To use this command simply type LIST on the command line then press enter and select the object from drawing area about which you want to know and press enter again. DIM This command was introduced in AutoCAD version and it can be used to make most of the dimensions like Linear, aligned, radius, diameter and baseline.

When the scale of these text entities are changed the base point will remain fixed. BASE Using this command you can change the base point of a drawing without changing its origin.

Computer Aided Design: A Conceptual Approach

This is especially helpful in the situation where you want to insert the drawing into another as a Xref. By default, AutoCAD takes origin as the base point which can be modified using this command without changing the origin.

UNITS Using this command you can set the drawing units and other settings like the precision of linear and angular dimensions and default rotation angle. ML Using this command you can make a multiline geometry which contains multiple parallel lines. I have made a simple table by importing blocks of design center as shown in the image below.

DS Using this command you can open the drafting settings window which can be used to change settings related to status bar options like object snap, polar tracking, snap and grid settings. In a previous text Engineering Drawing and Computer Graphics , two of the authors introduced the basic principles of engineering drawing and showed how these were related to the fundamentals of computer graphics.

This boundary can be used to find the area of the enclosed region or for many other applications. You change the value of this system variable to 1 to make transparency visible or 0 if you want to make it invisible.

If for some reason your command line is hidden from the drawing area, then use this keyboard shortcut to bring it back. Supported by sufficient number of systematically solved examples with line sketches, it will inculcate better understanding and interest in CAD among the common engineering students.

For each topic, the mathematics is given, together with the PLaSM implementation usually with a few lines of readable code and some worked examples.

Combines excellent coverage of the theory with well-developed examples Numerous applications eg.
