Command:OFFSET

• Take offset of 3" on both the sides of the line

Command:TRIM

• TRIM the extra line from the window

STEP6

• Select the window panel region and give height of 8"
• Select the region between for the window and height of 9" //For the outer border

Command:COPY

• Copy the window design and paste it in the wall at height of 4'6" //4'6" from the base at the line of window plan

//Copy the windows at the height given according to the drawing

STEP7

Command:SUBTRACT

• Selectt the object //From which u want to subtract
• Select the object which u want to subtract //select teh windows

//SUbtract all the windows from the walls

Command:COPY

• Now Copy the windows on the subtracted winodws place //Do it for every windows

Command:LAYERS

• Select the walls and assign the layers to it
• Select the windows adn assign the layers

STEP1

• Go to the right side view
• Create the side view of stairs

Command:LINE

• Draw vertical line of 6" //For the riser
• Draw horizontal line of 1' //For the tread

STEP2

Command:COPY

• Select the tread and riser
• Select the start of the riser as basepoint //Basepoint to copy
• TYpe "A" for the array command //To copy multiple at a time
• Enter the value of array 10 //For 10 copies
• select the end of the tread to copy

STEP3

Command:LINE

• Extend the line of the last tread landing to 3'
• Drop a vertical line down of 4"
• Draw a line joining points of tread and riser intersection //To provide the base slab

Command:OFFSET

• Take offset of the line of base slab of 6"

//Join the line of the offset of the bse slab and base of tread of first and last landing

STEP4

• Select the object //From which u want to subtract
• Select the object u want to subtract //Select the door
• Click enter

//Repeat the copy command to copy the door on the open space on the wall

STEP6

Command:LAYER

• Create layers of name dimensions,walls .doors, lintels,chhajja etc
• provide different colours to them //It ease in distinguishing the object

Command:DIMLINEAR
