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

Commands used:

1. Block.
2. Insert.
3. Attributes.
4. Field.
5. Rectangle.
6. Line
7. Text.
8. Array.
9. Mirror.
10. Copy.
11. Offset.

1. Create the templates as shown in Figures. Take the size of the title block as per industry standards or you can assume it as per the size of the paper. Use text and attributes wherever required. After creating the title block you need to save it as a block with names: Custom1_titleblock and Custom2_titleblock, respectively.

Aim: Creating templates, inserting text and attributes

• Custom 1_ title block
• Custom 2_ title block

Procedure:

Custom 1_ title block:

• Create a rectangle of size 66.63mm and 158 mm
• Divide it with line for the text box into columns
• For rows, take offset of 5,10,5,5,8,30,15,15,20,20,10,15 mm.
• By multiline text, type rev, description, by, date on the first row by text height 2.5 and style - Times New Roman.
• As it is repeated in the other two rows, take array give column as 1, rows as 3, spacing between rows as 7.
• Again, use multiline text and type the required text in caps with text height 1.5 and style as Times New Romans.

Creating block:

Command "B" - block definition dialogue box appears- give name as "Custom1_ title block"- select pick point and select a point in the table- select the object- select the whole table including the text.Give scale uniformly and tick allow exploding.Select convert to block option.

As we have selected retain the object it wiil be retain and same as the actual drawing and a block is creted for the objects that we have selected .If we want to use the block goto insert select the object and insert it.

Custom 2_ title block:

Draw rectangle of 252 and 46 mm With lines divide the to the required rows and columns.

With the use of multiline text insert the following: height 2.5.

Create a small rectangle at the right corner, explode it, create rows and columns.

By attributes, create the text inside it.Command "ATT" - attribute definition dialogue box appears.

Insert the tag line - tag we are giving, visible before creating the block.

Prompt: Question we need to add what we need to enter

Default: the value shown in drawing after making it as a block.

For e.g.: In the first-row 1st column "C" is the text to be displayed. Command "ATT"

Place the tag line on the place we need to hear 1st row 1st column of the box created.Create attributes similarly for the rest of the text.The attributes created are:

Now create a block Command "B" with name Custom2_titleblock, select the whole title block and make it as a block.After creating it as a block we can see that all attributes will change to their default values.

Result:

i) The Custom_1 title block is created:

ii) The Custom2_tiltleblock is created:

2. Create the doors type for warehouse as shown in the Figure. You need to create each door type as per standard size or given dimensions. Create the blocks of this door type after creating them.

Aim: Creating doors for warehouse and placing it in blocks:

1. Door 1 - 2330 x 2750 mm
2. Door 2 - 2330 x2750 mm

Procedure:

Door 1 -2330x2750mm:

Create a rectangle of size 2330x2750mm.

Offset 50mm as a frame. 90mm for the left side.Explode the rectangle.

By divide "DIV" divide the top line into 4 segments.From the division point, draw lines vertically to divide it into shutters.

Offset 25mm on both sides for the thickness, delete the centre line.

Create a rectangle to show the panels.Offset 20mm from the 1st rectangle and offset 100mm from the 2nd rectangle.Draw lines joining the corners of the outside and inside rectangle.

Create the panel as a block, so that it is easy to copy.Create lock by rectangle command, and fillet the corners with radius 5mm.

By using the copy all the frames are copied.

Layer is created and all the objects are kept in different layers.

Creating block:

Command "B" - give name as door 1 - pick point- select corner point- select object - select the full object - ok.Select scale uniformly and allow exploding.

Door 2 -2330 x2750mm:

Create a rectangle of size 2330x2750mm.Offset 50mm as a frame. 90mm for the left side.Explode the rectangle.

By divide "DIV" divide the top line into 4 segments.From the division point, draw lines vertically to divide it into shutters.To make the points visible, Command "DDPTYPE" select the style of point

Offset 25mm on both sides for the thickness, delete the centre line.Create lock by rectangle drawn on opposite sides and fillet the corners with radius 5mm.

Make layers and insert lock, frame in different layers

Create it as a block "B" - pick a corner point - select the whole door -tick the box of scale uniformly- explode.

Result: The doors block was created.

1. Door 1:
2. Door 2:

3. Create each symbol as a block with the name given in the legend. After creating the blocks arrange them in the legend as shown in the Figure

Aim: To create the blocks and legend as shown in figure

Introduction: The legend given consists plan of the electrical component along with the name of the component. First blocks are created using plan views and respective names. Then the legend is prepared using field box command in which object and object name are selected.

Procedure:

• Click ‘ok’

Step 3: Creating Legend

• Create a rectangle of size 22000mmX9500mm
• Explode the rectangle using rectangle command
• Offset the top edge to a distance of 1000mm to bottom
• Offset the last offset line to a distance of 500mm to bottom
• Offset the last offset line to a distance of 1000mm to bottom
• Offset same until the bottom edge
• Using divide command, divide the top edge into three segments
• Draw the line connecting two lines to the bottom edges
• Offset the lines drawn to right to distance of 1500mm

Step 4: Adding Blocks and Field Boxes

• Add All the blocks into respective boxes
• Go to Insert tab and click on field box
  • In popup box go to Object category
  • Click on select object and select the object required
  • Set format as first capital
  • Click on ok and place the text in box next to the block

Result:

The result consists of an electrical legend created from the figure. Initially blocks are created using commands. Then table is drawn using line command and offset. Add blocks and field boxes respectively. The layers are assigned respectively.

• All the dimensions mentioned are in millimeters
• Dimensions and text are assigned using dimension layer and text layers

4.Create the door type for residential building as a block. Save the name of the blocks as type. Use given dimensions or assume dimensions as per industry standards.

Aim: To create the door type 1 to 6 as shown in the figures.

• All the dimensions mentioned are in feet and inches
• Dimensions and text are assigned using dimension layer and text layers

5.Create each shape as a block as shown in the Figure. Save the block and insert them on the table as shown in the Figure.

Aim: To create the blocks and reinforcement schedule as shown in figure

Introduction: The given figure consists of different reinforcement details such as type of reinforcement, number of rebars, dimensions, total length of reinforcement, and weight details of rebars. The aim of this question is creating the rebars using dimensions, covert these rebars to blocks and create the table containing the data.

Convert them to block and add the values of attributes while inserting the blocks

Step 4: Creating Data from data extraction

Go to insert tab and click on Extract Data in linking & extraction tool bar

• Click on create a new data extraction and press next
• Set the location of Data extraction
• Click on select objects from current drawing and select all the blocks created and click next
• 
• Select only the data that needs to be extracted and click next
• Click on only attributes and click next
• 
• Check the preview and click next
• 
• Click on insert data extraction table into drawing and click next
• Make the table settings and click next and finish

Step 5: Creating Table

Draw a table from the annotate tool bar

After creating table click on second column and from table creation tool add a column to the left to add figures

Result:

The result of this challenge consists of rebars schedule drawing made from the given figure. Initially layers are created for reference. Then attributes are created for adding data for all types of rebars. Rebars are created as per the dimensions in figure given. Attributes are copied to each of the rebar and created as a block. Then data is extracted from the all the blocks using extract data command. Then all the data is copied to a table along with figures. Result is provided in two pics one with blocks and attributes and in table format

• All the dimensions mentioned are in feet and inches
• Dimensions and text are assigned using dimension layer and text layers
