Improving my drawing laying out in General Discussion Posted 8 hours ago I try and limit my use of colour on most line drawings. Generally everything is black and white. If I use a colour (for example to make annotations or dimensions clearer) then I try and do it in a way such that the drawing is still legible if converted to black and white. This is largely a habit left over from the days when drawings went out on paper, and then may have ended up getting photocopied before reaching their final destination. Arguably this is no longer so important, because drawings are now mostly distributed digitally. However... not everyone has a colour printer, so there is still the possibility that a black and white version of a "colour" drawing is the one that ends up on site and gets built from. In any case I find it's quite a good discipline to try not to rely too much on colour. I often see drawings where multiple colours have been used as a lazy way of putting some thought into legibility. Communicate as much as possible using linetype and lineweight. If a drawing is getting very crowded with information, this probably means that you need to change the scale or split it into more than one drawing, each showing different types of information. Where separate drawings show different bits of information relating to the same location or area... split that information in a way that makes sense and is useful to those who will be looking at it. Usually for construction drawings that means splitting by trades.
