Autocad Lineweight Standards Architecture

It doesn't matter what scale you print, your lineweights will always be the same thickness according to the ctb plot style you choose. Check this link: What you say is correct, however from my searches there is no such ISO or DIN standard. What is often quoted as a standard is the Rotring technical pen nib colour coding. The pens were called Rotring ISORapid technical pens and the ISO led people to believe that it was an ISO (International Standards Organisation) standard.

Feb 21, 2017 - 'Architectural Graphics 101: Line Weight' will explore the benefit of using line. PS – for those you you who just can't stand it, my AutoCAD pen. Drawing for Architects Basics: Line Weights. All architectural computer-aided design programmes have in-built. The standard rule is that anything that is.

I have not been able to locate any ISO standard number for any document. The problem with the so-called ISO/DIN standard is that it does not follow the Rotring colours anyway. Brown (for a 0.5 mm pen) is not a standard colour and it is difficult to see on a white background so red is substituted but red is actually the colour for a 0.18 mm pen, magenta is substituted for red because red is used for what should have been brown, blue for a 0.7 mm pen is difficult to see on a black background so cyan is substituted, yellow for a 0.35 mm pen is also difficult to see on a white background so a colour is substituted for it, and so on. In the end there are not many colours that actually match the technical pen colours anyway. The resource that anyone should use as their first point of call when preparing technical drawings is their local national standards bodies standard. In Australia/New Zealand it is the AS/NZS 1100.

Part 101 is the General Principles applying to all disciplines, 201 is Mechanical, 301 is Architectural, 401 is Survey, and 501 is Structural. Such standards set out what line weights should be used where, the size of dimensional elements, and standard text sizes and fonts, among other things. Anyone preparing technical drawings should have a copy of the standard relevant to their discipline. Line weights are generally modified from the old days of manual drafting: 0.13, 0.18, 0.25, 0.35, 0.5, 0.70 mm. People who have not had this pleasure tend to use rounded up decimal widths: 0.1, 0.2, 0.3, 0.5, 0.7, 1.0 etc Line weights are varied depending on the purpose of the drawing, ie a roof plan will have the roof outline in a heavier linetype, and possibly the walls supporting it in a faint line. Structural Engineers tend not to show windows, but have heavier wall lineweights.

BS EN ISO 128 gives some guidance also.
