Procedure

Custom 1_title block

• Creating a rectangle of size 66.63mm and 158mm
• Divide it with line for the text box into columns
• For rows , take Offset of 5,10,5,5,8,30,15,15,20,20,10,15mm
• 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 to new Roman
• Creating the blocks by using command B

Custom 2_title block

2)Aim : Creating doors for warehouse and placing it in block.

1. Door 1- 2330x2750mm

2. Door 2- 2330x2750mm

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.

Weatherproof socket: Insert text "w" in the triangle.

Duct base section: Draw a rectangle - select the bottom grip point - select add vertex - then pull the vertex to create a bend, with line draw the lines.

Wall bracket: With rectangle draw the base, create a circle, draw a line connecting the rectangle and circle, draw a cross line inside the circle.

Picture lamp: draw two rectangles connected by a line.

Creating them as block:

• Command "B" give name as single gang switch - pick a point - select object (created single gang switch) - tick scale uniformly and allow exploding options.
• Similarly define each one of them as block giving the respective names.Do the same procedure for the remaining symbols.
• Creating and arranging hem in layers:
• First create a rectangular table having 10 rows and 6 columns.
• Place each of the blocks in the respective rows and columns.
• To enter text with the block from the insert tab- select field- select object -select block.
• E.g.: for single gang switch - select from the field. - select uppercase in format.
• Place the text in the respective rows give text heiht to 150.
• Similarly place all the title inside the legends.
