  • Layer Properties
  • Qleader
  • Multi Leader
  • Match Properties
  • Ortho

Procedure:

1. Title Block:

• Firstly draft the layout as shown in the question of required size.
• Then using the Attributes command insert various attributes at the required locations.
• Enter the Tag line, Prompt and Default display of the particular attribute.
• Then convert the layout into block.
• While inserting the block, a pop up window will be opened and we can fill in the information which needed to be entered into the Attributes.

2. Door Frames:

• Draw a rectangle for the outline of the door frame as per the given dimensions in the question.
• Now for taking the dimesions we can insert the picture of the door frame into the drawing.
• We can do this with the help of XREF command.
• Now scale the picture as per the dimensions and take the dimensions in the picture as reference for the drawing.
• After drafting the door convert it as a block with the help of Block command and give a name to the block.

3. Electrical Layout Legend:

• Create seperate blocks for each every object which is to be displayed in the legend.
• Give the names to the respective blocks as how they should appear in the legend.
• Now insert every block in a tabular format.
• Now go to Insert>Field Option > Object > Select the Object > Name > Select the Font Style > Enter.
• Place the Field as per the requirement.
• If there are any changes to the block name, update the field and the name of the object will change.

4. Doors:

• Draw a rectangle for the outline of the door frame as per the given dimensions in the question.
• Now for taking the dimesions we can insert the picture of the door frame into the drawing.
• We can do this with the help of XREF command.
• Now scale the picture as per the dimensions and take the dimensions in the picture as reference for the drawing.
• After drafting the door convert it as a block with the help of Block command and give a name to the block.

5. Bar Bending Schedule:

• Create the Shape and size of the bars as per given in the question.
• Create the block for each and every object and give an appropriate name.
• The with help of Attributes give the requried data to the block.
• We can use the help of Field command similar to that of its use in the drafting the legend of electrical layout.
• Arrange all the data similarly for aesthetic point of view.

Result:

The blocks are drafted and created for the Title Block, Electrical Layout Legend, Door Frames and Bar Bending Schedule. The Attributes and Field commands are used whenever usefu;.

The Drawing are attached.
