Obviously one definite common sense ‘rule’ is that the letter ‘A’ or ‘A-A’ (describing the extent of the view) should only be used once on the same sheet, but it can be used for something else on a separate numbered sheet. Connected (often surrounding the circle) is an arrow pointing towards what this relates to. Often this information is conveyed with a small circle cut in half with for example the elevation letter written in the top half and the sheet number below it. ‘Elevation A’ or ‘Elevation A-A’ and the sheet number where the corresponding drawing can be found. ‘Coding’ when it means referencing a part of a drawing within a number of separate sheets of drawings must include both the view title i.e. In whatever case though, it must be made clear not only the direction seen from but also the ‘point’ in space seen from (especially with sections). they take much less time to write, and they are more easily found and recognized!įor example, the simplest method when cross-referencing parts on the same sheet would be to label or ‘code’ a drawn view of a wall as ‘Elevation A’ and place the same ‘A’ beside its representation on the ground-plan. Using just letters and numerals rather than descriptive words has proven more effective in practice. One could just call this ‘labelling’ in normal language, but as the name implies shorthand letter codes are used rather than words and it relies on everyone understanding how to read them. relating an elevation to its place on the ground-plan) or from one sheet to another, often when details of a structure in an elevation need to be drawn in a bigger scale on a separate sheet. ‘Coding’ is a recognized term used in technical drawing to describe the cross-referencing of parts of a drawing, either within the same sheet (i.e. What’s most important is that the true length of the wall should always be clearly indicated with a written measurement. for a completely plain wall or a regular pattern. Obviously this is only an option if no information is lost by doing this i.e. if a structure or distance needs to be shown condensed (because the whole can’t be fitted on the paper, or space needs to be saved). This lexicon will go in the Technical Drawing section, but as usual I’m previewing it as a post mainly so that I can tag the contents.īreaking the line i.e. For example, illustrations are certainly needed, but I have too little time to spare for these at the moment. The lexicon is a starting point a framework which will be built upon. Besides, part of my purpose in writing things here is to organize information for myself and I find it easier to locate things if they’re arranged alphabetically. I recommend printing the protractor on a nice cardstock for sturdiness and durability.I’ve put this together to follow on from the simple summary of the basics posted at the beginning of September. I know that glossaries like this are usually written after everything important has been said but sometimes it’s much more interesting to reverse the logical order.
