Aim: Creating templates, inserting text and attributes

• Custom l_ title block
• Custom 2_ title block

Procedure: Customl 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 "Customl_ 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 wil 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 Custom_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.

• 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.

Procedure:

• Creating electrical symbols
• Single gang switch: Draw a circle of radius 64mm and with line draw an inclined line vertical and horizontal line perpendicular to the inclined as required.
• Double gang switch: Draw circle and draw two horizontal lines and a vertical incline line.
• Triple gang switch: Draw circle, 1 vertical incline line and three horizontal lines.

• Double two-way switch.: Draw same as double gang switch and create donout.
• Triple two-way switch: Draw same as triple gang switch and create donut.
• Switch cross: Create a circle and donout inside and with line command draw an inclined vertical and perpendicular horizontal. Mirror the line in both directions.
• Switch serial: Copy the switch cross and delete two bottom lines, remove the donout also.

• Floor single socket for lamp: Draw a rectangle surrounding single socket for lamp
• Floor socket double: Create two single socket and place a rectangle surrounding it.
• Floor socket single telephone: Draw a single socket, a triangle and surrounded by a rectangle.
• Floor socket double, telephone: draw 2 single socket and a triangle surrounded by a rectangle.
• Telephone socket. Draw a triangle
• Internet socket : Insert text "i" in the triangle.
• Tv socket: Insert text "TV' in the triangle.
• TV 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 height to 150.Similarly place all the title inside the legends.
