Here is an article from the latest Structure magazine. I found it interesting and factful regarding how drawings and engineering schools have changed over the years.
This was a very interesting article. I have reviewed it and came up with the following errors in the CAD detail:
1. Weld symbol at bottom, is wrong vertical fillet element should be towards the arrow.
2. Weld symbol at bottom is pointing to the angle and not the proper weld plane required.
3. Weld symbol at bottom calling for weld all around, not sure if this is really required.
4. Weld symbol at top, is wrong vertical fillet element should be towards the arrow.
5. Weld symbol at top is not possible for continuous angle.
6. Weld symbol at top does not require all around symbol
7. Continuous angle (L6X6) is show as same height of 5.25-inch slab.
8. Field weld symbol is all hosed up from AWS standards (flag is pointing in wrong direction, vertical leg of fillet is on wrong side, weld all around is not required and detail indicates a bolted connection).
9. Field weld symbol is pointing to a bolted connection.
10. W18 is on wrong place of leader line
11. Sizes for all angles, supporting the curtain wall, are missing
12. Detail indicates bolted connection but does not specify bolt size and quantity.
13. Double clip angle connection, it calls for full depth yet is does not reflect that.
14. Double clip angle connection does not specify the angle size, bolts size and quantity and does not give selection guidance to the detailer/fabricator.
15. Double clip angle connection is not drawn to scale. Too many bolts and does not comply with standard practice (bolt spacing)
16. Weld symbol of the angle under the top flange of W18 is not called out
17. Detail does not show the cope required between top flanges of W14 and W18
18. Detail indicated WWF at slab mid depth but does not call it out
19. Detail show a shear stub but does not call it out and it is on wrong beam
20. The detail does not indicate the dimension from center line of W18 to the curtain wall (inside or out side face)
21. The placement of the vertical angle and the top and bottom flanges is wrong. Hidden lines are not show properly on both locations.
22. Scale is missing on the section/detail
23. Top of slab elevation is not in proper location
24. Bottom angle at curtain wall is not called out, not dimensioned, it fastening to vertical angle is not specified and it is shown as penetrating the curtain wall but not sure how that is going to work
25. W18 cross-section does not depict true hot rolled section
26. Decking is called out ass 2 inch and is not drawn to scale
27. Termination of the decking over W18 is not clear
