CAD layer standards
Most common: *'' BS 1192'', which relies heavily on the Code of Procedure for the Construction Industry *''AIA Cad Layer Guidelines'', 2nd edition (1997), has great usage in the USA; *'' ISO 13567-1/3'', International standard, common in Northern Europe; *Line-thickness
Thickness for pens and plot: '' Gray, Red, White, Yellow, Magenta, Blue, Green''. In AutoCAD usually parts to be printed in black are drawn in 1 to 7 basic colors. Color layer: Green-Center, Magenta-Measure of length, and Blue-Hidden.Text and dimension
Heights: , , , (stroke thickness (lineweight) should be 0.1 of the character height). Font styles: "Romans.shx – Romantic Simplex", "ISOCPEUR.ttf". Exceptional use of screen fonts (arial, Times New Roman etc.).Scales
* 2:1, 20:1, 200:1 ... * 1:1, 1:10, 1:100 ... * in = 1 ft * in = 1 ft * in = 1 ft * in = 1 ft * in = 1 ft * 1 in = 1 ft * in = 1 ft * 3 in = 1 ft (QUARTER SCALE) * 6 in = 1 ft (HALF SCALE) * 1 ft = 1 ft (FULL SCALE)File naming standards
* BS 1192: 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=assembly 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). * AIA *AEC Samples: ZE1G-124.dwg, XE1G-100.dwg *AEC (UK) 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). *Other local: 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). it produces a large number of photos that could then be CAD into a file format.Mechanical CAD standards
Model-based definition
Model-based definition (MBD) is a method of product specification using elements within 3D models as defined by ASME Y14.41-2012. ASME Y14.41-2012 is based upon ASME Y14.5-2009 symbols and definition methods, such as Geometry Dimensioning and Tolerancing (GD&T). Subscribers of International Organization for Standardization (ISO) have the standards ISO 1101 and ISO 16792 for model-based definition.Geometry quality
VDA 4955Product 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 analyze 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 CAD file formats. In 2006/2007 Part 59 of STEP ISO 10303-59 ''Product data representation and exchange: Integrated generic resource: Quality of product shape data'' is under development. It defines how to represent quality criteria together with measurement requirements and representation of inspection results.See also
