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

CREATING BAR BENDING SCHEDULE, DIFFERENT DOOR TYPES, AND CREATION OF STANDARD DRAWING TEMPLATES USING AUTOCAD

Introduction:

BLOCKS

It includes static blocks, dynamic blocks, white block, redifining blocks, exploring blocks

A block is a collection of objects(lines, arcs, circles, text etc) that form a more complex entity that normally represents an object in the real world eg.a door, a chair, a window, a computer.

Library of blocks can be built up consisiting of the parts that you require many times in your workday. These blocks can be stored in a seperate folder and even on a network, so that all drafters have access to them. Eg: plumbing parts, valves, elbows etc. as well as electric symbols or furniture.

TO INSERT A BLOCK

1. Click home tab> Block panel> Insert. Find

2. To insert a block, do one of the following:

• Select an icon or a blockname from the block definitions displayed in gallery. Click the location for the block refences.
• Click therecent Blocks option. From the Blocks palette, click and place theblock reference. You can also use the drag-and-drop method for speed, but this method doesn't use the settings specified under Insertion Options.
• Click the Blocks from Other Drawing option. From the Blocks palette, use either the click-and-place or drag-and-drop method to insert the block refernce. To choose a different drawing file, click the Browse... control and specify the drawing file

3. At the bottom of the blocks palette, choose one or more options to control the placement, scale, rotation, and automatic repetition. If you want the objects in the block to be inserted as individual objects of as a single block, select Explode.

4. Click OK

ATTRIBUTES

An attribute is a label or tag that attaches data to a block. examples of data that might be contained inan attribute are part numbers, prices,comments, and owner's names.

Attribute information extracted from a drawing can be used in a spreadsheet or database to produce a parts list or a bill of materials. Toc can associate more than one attribute with a block, priovided that each attribute has a different tag.When you define an attribute, you specify

• A unique tag that identifies the attribute by name.
• A prompt that can be displayed as the block is inserted.
• A default value that is used if a variable value is not entered at the prompt.

Aim:

To create the titleblock named Custom1_titleblock (1.a) and Custom2_titleblock(1.b) using block and attributes command in AutoCAD.

Procedure:

• Initially set the units of the drawing as decimal (millimeters).
• Now, set the limits of the drawing
  • Specify the lower left corner: (0,0)
  • Specify the upper right corner: (50000,50000)

Custom1_titleblock:

• Now, choose the line command to draw the lines to complete the table.
• Using the mtext command draft the texts.
• From the properties change the colour as required.

• Now, the next step is to convert it into block.

• Then click ok and it is converted into a block.

Custom2_titleblock:

• Again choose line command to draw the table.
• Using the mtext command draft the texts.

• Now, the next step is to convert it into block.

• Then click ok and it is converted into a block.

2.

Aim:

To create the door types for warehouse and to convert the same into blocks.

Procedure:

• Initially set the units of the drawing as decimal (millimeters).
• Now, set the limits of the drawing
  • Specify the lower left corner: (0,0)
  • Specify the upper right corner: (8000,8000)

Door 1:

• Draw a rectangle using the command rec having dimension 2330mmx2750mm.

• Now, using the line and offset command draw the panels of the door.

• Now, we have to create the lock for the door, which created separately.
• This can be created using rectancle and fillet command.
• Then convert it to a block.

• Now, place this lock on door at appropriate position.

• Now, provide the dimensions to complete the figure.

• Now, we have to convert this door to a block. So for this, type block in command prompt and do the necessary steps to convert to block.

• Then click ok and it is converted into a block.
• Hence, the block has been created.

Door 2:

• Draw a rectangle using the command rec having dimension 2330mmx2750mm.

• Now, using the line and offset command complete the door.

• Now, place the lock that is previously created in the current drawing by insert block option.

• Now provide the dimensons and text to complete the drawing.

• Now, we have to convert this door to a block. So for this, type block in command prompt and do the necessary steps to convert to block.

• Then click ok and it is converted into a block.
• Hence, the block has been created

3.

Aim:

To create a symbol legend with each symbol as a block with the name .

Pocedure:

• Initially set the units of the drawing as decimal (millimeters).
• Now, set the limits of the drawing
  • Specify the lower left corner: (0,0)
  • Specify the upper right corner: (5000,5000).

• Inorder to create a symbol legend, first of all create all the symbols individually and then convert them into blocks.
• Now, first one is single gang switch, so for that type c to draw a circle, type L to draw line.
• After drawing convert it into a block.

• Hence it is converted to a block.
• Similarly convert all the symbols into bocks after drafting.

• To draw lines use command L.
• To draw an arc, type arc in the command prompt.
• To draw rectangle or square choose command rec.

• Use command L to draw triangles.
• Command rec to draw rectangles.
• Mtext to place texts.

• Hence, all symbols have been converted to blocks.

• Now, these symbols has to be inserted into a table along with their names.
• Inorder to draw a table use line command and complete the table.
• Then insert the blocks and their names into the table.
• Names can be inserted from the field option in insert tab.
