How to draw architectural CAD symbols above sea level?
Users questions: We see below, the figure marked the two altitude 302.6 meters and 302 meters. Both the front elevation with a triangular arrow symbols to mark? How does this deal? In fact, the most stupid way is also possible, that is, drawing an inverted isosceles triangle, then draw a straight Cable. Another simple point, that is the way to the block. However, I've got a lot of elevation need to mark, how to quickly solve the problem? I think the use of "lead" approach. However, CAD comes with a variety of wire styles are not the symbol. Is how we do it? 7777 77 properties with a block with itself if the correct measuring point Z coordinates, there are specialized measurement software can be directly marked elevation.
