AEC (ARCHITECTURE ENGINEERING AND CONSTRUCTION) STANDARDS CAD Layer Standards Most common:
Samples of standardised layers: A-B374--E- (ISO13567: agent Architect, element Roof window in SfB, presentation graphic element); A-37420-T2N01B113B23pro (ISO13567: agent Architect, element Roof Window in SfB, presentation Text#2, New part, floor 01, block B1, phase 1, projection 3D, scale 1:5(B), work package 23 and user definition "pro"); A-G25---D-R (ISO13567: agent Architect, element wall in Uniclass, presentation dimensions, status Existing to be removed); A-G251-G-WallExtl-Fwd (AEC(UK): agent Architect, element External Wall in Uniclass, presentation graphic element, user definition "WallExtl" and view Forward); A210_M_ExtWall (BS1192: agent Architect, element External Wall in SfB, presentation model, user definition "ExtWall"); A-WALL-FULL (AIA: agent Architect, element Wall, Full height). Line Thickness Thickness for pens and plot: 0,13mm, 0,18mm, 0,25mm, 0,35mm, 0,50mm, 0,70mm, 1,00mm. In AutoCAD usually parts to be printed in black are drawn in 1 to 7 basic colors. Text and dimension Heights: 1,8mm, 2,5mm, 3,5mm, 5,0mm, 7,0mm (relative thickness are 1/10 of the heights). Font styles: "Romans", "ISO CP". Exceptional use of true type fonts (arial, etc.). Scales 1:1, 1:2, 1:5, 1:10, 1:20, 1:50, 1:100, 1:200, 1:500, 1:1000, 1:2000, 1:5000, 1:10000, 1:20000, 1:50000 and so on. File Naming Standards
Discipline (1 char), Element (2 char, using SfB Table 1 or Uniclass), Drawing type (1 char, P=preliminary, X=special/xref, L=layout, C=component, S=schedules, A=assemby drawings, K=co-ordination drawing), Unique number (3 char), Revision (1 char, A=emission, B,C,D...= revisions). Samples: A22P012G.dwg (architect, internal walls in SfB, preliminary design, sheet 012, revision G).

Project (unlimited char), Discipline (2 char max, recommended mandatory), Zone (optional), View (1 char, rec.mand.), Level (2 char, rec.mand.), Content (rec.mand.), Sequential number (up to 3 char); Samples: 1234-A-Off-P-M1-Furn-11c.dwg (project #1234, architect, office zone, plan, mezzanine 1, furnitures, version 1.1 revision c) , A-P-01-Part (architect, plan, 1st floor, partitions), 1234-A-S-055.dgn (project #1234, architect, section, sheet 055), A-S-xx-AA.dwg (architect, section, full building, section AA), A-P-x-Grid.dgn (architect, plan, all floor, grid), 1838-S-C-P-03 (project 1838, structures, building C, plan, 3rd floor).
Job number(4 char), Agent (1 char), Section (4 char), phase (1 char), sheet number (2 char), revision (2 char) Samples: 0512-A-00A_-1-01-02.dwg Job number (3 char), View (2 char), section (2char), phase (1 char), revision (1 char) Samples: 123p0s2d0.dwg (job 1239, plan, 2nd floor, definitive drawing, emission), 459s0BBD0.dgn (job 123, section B, definitive drawing, emission). MCAD (MECHANICAL) STANDARDS Geometric Dimensioning and Tolerancing Industry standards for defining PMI , a 3D extension of GD&T , include ASME Y14.41 Product Data Definition and ISO 1101 Representation of specifications in the form of a 3D model. Geometry Quality VDA 4955 PRODUCT DATA QUALITY PDQ is a field of PLM relating to the quality of product data, particularly the geometrical and organizational quality of CAD data. Checkers, software that analysis CAD data formats, are often employed before and after Data Translation . The checkers can check the organization and quality of the data against internal company standards and international or industry standards. These checkers can be built into specific CAD packages or work on a number of . SEE ALSO |
