Creating a Layout, Section and Elevation with dimensions using AutoCad

Q1

AIM- To Create the Plan and Sections of given drawings using proper dimension techniques and dimension styles to document the project and assuming the sizes of the doors and windows as per construction standards.

INTRODUCTION- From the given drawing of residential building plan with multiple master bed room plan, is to be drawn in autocad with considering all dimension in mm for and assuming all doors, windows dimensions using construction standards.

As this drawing will have section along A-A and B-B .

PROCEDURE-

1. first create new file, set units in mm , dim-style and limit as per suitability of planned drawing to be draw in autocad.
2. Since there was no clear distances were mentioned in drawing and many assumption were to be done with respect to construction practices or standards.
3. Calculate the distances of wall to wall and check in section for references and if any dimensions are omitted than, missing data is taken out and along with wall dimensions column distances are also found out.
4. Than using coordinate system draw line along width and length of plan and then creating a mirror along diagonal create a rectangular plot.
5. Setting up the dimension for doors windows, exterior walls and interior walls and structural elements like column, beam, stairs. Reference from given drawings.

Below table will show about adopted dimension-

ITEMS	DIMENSIONS
WINDOW- W1	900 mm
W2	1200 mm
W3	1500 mm
W4	600 mm
DOOR – D	1000 mm
D1	900 mm
D2	750 mm
EXTERIOR WALL	250 mm
INTERIOR WALL	125 mm
COLUMN	250 x 400 mm
BEAM	250 x 400 mm
STAIRS - 1	R-143.75, T- 250 mm
STAIRS - 2	R-158.36, T- 250 mm

6. Start with creating above mentioned item in Autocad and setting them as separate Blocks so that they can later can be placed at precise location in plan.
7. Using XLINE create wall inside as per the dimension of room and later trim them on outside the plan along with trimming the line as per room dimension.
8. Now using column block place, them as per earlier calculated distances from drawing. Which are also Hatched with solid hatch as mention in Drawing.
9. Again, using the TRIM lines for door locations, with reference to above adopted table for drawing.
10. Using DTEXT command specifying text height to -1.5 and justifying it to left. Labelling to doors.
11. Similarly using window block of respective dimension are placed using MOVE and COPY tools following to Using DTEXT command specifying text height to -1.5 and justifying it to left. Labelling to windows.
12. Chajja are assumed to be with projection length of 600 mm for all windows. represented with different layer types.
13. Again using DTEXT tool keeping all text reference mentioned above used for labelling the rooms as per given in Drawing.
14. Using DIMLINEAR tool dimension of each room are shown. In this way plan view is completed
15. Proceeding to Section A-A then initially a copy of plan is taken out than , using Dot line section line is drawn with in the plan .
16. Next using the TRIM option , trimming the portion of plan and limiting plan view up to Dot line.
17. Later using XLINE horizontal a refence line is drawn which will at distance of height of building in elevation .
18. Later all line of wall are projected towards the horizontal line using EXTEND command, later from referred G.L , OFFSET of G.L line is created till roof level and then same is iterated till top in section view.
19. Using beam and column dimension from table are drawn at respective location From visible section A-A.
20. Using MULTI-LEADER labelling for ground level (G.L) material and at top for roof, parapet wall and O.H.T
21. Using the dimensional references from the plan view for stairs are drawn using POLYLINE later HACTHED with solid colour.
22. Proceeding to Section B-B then initially a copy of plan is taken out than , using Dot line section line is drawn with in the plan .
23. Next using the TRIM option , trimming the portion of plan and limiting plan view up to Dot line.
24. Later using XLINE horizontal a refence line is drawn which will at distance of height of building in elevation .
25. Later all line of wall are projected towards the horizontal line using EXTEND command, later from referred G.L , OFFSET of G.L line is created till roof level and then same is iterated till top in section view.
26. Using beam and column dimension from table are drawn at respective location From visible section A-A.
27. Using MULTI-LEADER labelling for ground level (G.L) material and at top for roof and parapet wall.
28. Using the dimensional references from the plan view for stairs are drawn using POLYLINE later HACTHED with solid colour.
29. DIMLINEAR is used for showing the dimension in sections A-A and B-B.

RESULTS – From this exercise of challenge Dimension analysis and reading of given drawing matching of plan view with sections and correlating to check missing dimension is required.

As plan view gives info about how its section shall be in X and Y direction as sections are pure reflection of plan in elevations.
