Creating Bar Bending schedule, Different Door types, and Creation of standard drawing templates using AutoCad

AIM : To Creating Bar Bending schedule, Different Door types, and Creation of standard drawing templates using AutoCad

INTRODUCTION:

AutoCAD offers various tools to perform different tasks. The various tools which are used for drafting in this project are briefly described here. These draw tools include: - line,Construction line,rectangle,polygon,polyline,circle,elepse etc.

1. Rectangle - Command used is REC. It can also evoked from ribbon, toolbar, tool pallettes. Follow the commands in AutoCAD to complete the rectangle. Different ways by which rectangle can be drawn are:

• Drawing rectangle by specifying two opposite corners.
• Drawing rectangle by specifying area an one side length.
• Drawing rectangle by specifying their dimension.
• Drawing rectangle at an angle.
• Drawing using different options like chamfering, fillets, width, thickness, elevation.

2. Regular polygon - Command used is POL. Other ways of evoking the tool is through ribbon, tool bar and tool pallettes. This tool is used to make a polygon with minimum of 3 sides and a maximum of 1024 sides. Different ways of drawing polygon is:

• Drawing a polygon by specifying the centre of the polygon:
  • Drawing an inscribed polygon using centre of polygon option.
  • Drawing a circumscribed polygon using the centre of polygon option.
• Drawing a polygon by specifying the edge.

3. Polyline - Command used is PLINE or PL and is also evoked through ribbon, toolbar, tool pallettes. There are two types of polyline: 2D and 3D. Different options in polyline includes arc, halfwidth, length, width. It is possible to switch between an arc and line anytime in between the drawing.

Polyline is a very important tool in utility drawing like pipelines, sewage lines etc.

4.CONSTRUCTION LINE.

Construction lines (also known as xlines) are temporary line work entities that can be used as references when creating and positioning other objects or line work. Construction lines are either circles or straight lines that extend to infinity in both directions.

The following prompts are displayed.

Select line work under cursor

Specify the line on which we want to base our construction line.

Enter to select points

1. Specify a point to define the root of the construction line.
2. Specify a second point through which the construction line should pass.

5.LINE:

The command used is L. The line object is the most basic and common object in AutoCAD drawings of any discipline.Each segment is a line object that can be edited separately, assigning properties such as layer, linetype, and lineweight. The simplest method to draw a line is to click two locations in the drawing area.

6.CIRCLE:

Command used - CIRCLE or C.Creates a circle based on a center point and a radius or diameter value. It consist of different types of methods to draw as mention below.

• Center, Radius
• Center, Diameter
• 2 - Point
• 3 - Point
• Tan, Tan, Radius
• Tan, Tan, Tan

There are various modification tools in AutoCAD which are used to modify the sketched objects and these includes move, copy, offsetting, rotating, Scaling of sketched objects, filleting, chamfering etc.

Chamfer: A bevel or chamfer is-

• an angled line that meets the end-points of two straight 2D points.
• a sloped transition between two surfaces or adjacent faces on a 3D solid.

The distances and angles that we specify are applied in the order taht we select the objects.

Fillet: A round or fillet is-

• an arc that is created as tangent between two 2D objects.
• a curved transition between two surfaces or adjacent faces on a 3D solid.

Offset: It is used to create concentric circles, parallel lines and parallel curves.

Object Snap: Object snap provide a way specify precise locations, such as endpoint, mid-point etc., on objects whenever we are prompted for a point within a command.We can offset an object at a specified distance or through a point.

Rotate: This tool rotates object around a base point. An object can be rotated either by entering the angle of rotation, or drag the object around its base point and specifying a point location to which we want to rotate the object to. We can also enter c to create a copy of the selected objects, or enter r to rotate the selected objects from a specified reference angle to an absolute angle.

Copy: This command copies objects at a specified distance in a specified direction. With the COPYMODE system variable, we can control whether multiple copies are to be created automatically.

Move: It moves objects a specified distance in a specified direction. We can use coordinates, grid snaps, object snaps, and other tools to move objects with precision.

Mirror: This command is used to create a mirrored copy of selected objects. Using this command we can create objects that represent half of a drawing, select them, and mirror them across a specified line to create the other half.

Trim: It trims objects to meet the edges of other objects. There are two modes that can be used to trim objects, viz. Quick mode and Standard mode.

Extend: This command extends objects to meet the edges of other objects. To extend objects, we first need to select the boundaries, and then press Enter and select the objects that we want to extend. To use all objects as boundaries, we press Enter at the first Select Objects prompt.

Join: It joins the endpoints of linear and curved objects to create a single object. A series of finite linear and open curved objects at their common endpoints are combined to create a single 2D or 3D object. The resulting object depends on the types of objects selected, the type of object selected first, and whether the objects are coplanar

hatch : it is a command to fill the emty objects kind of any symbols of materials , masonrys etc.

BLOCKS : which is a command to create many objects as a blocks.that are saves in autocad software .those can be utilized & insert where ever it requiers.

• B + enter,type the name of block,pict the base point of block,select the objects convert to block, click ok.
• if we want to edit the block go with block edit option (Bedit).
