Shot in the dark here, but we have some bright people on this board. If anyone uses Autocad, I have a question.. I'm using 2009. I'm taking a beginning autocad class and I've learned enough that we're starting to dimension whole floors of buildings. Everything I know so far is in 2D though...
I need to layout a cyclone for a friend, and he gave me all the dimensions and I need to put it into an autocad drawing (Dwg). The bottom cone part is what he needs, and I have no problem laying it out in autocad, except that the dimensions call for an angle of 71.70 degrees.
For some reason when I use the line command and enter @45<71.70 it draws the line, but when I go to dimension it, it reads 72 degrees.
He wants exact tolerances on the drawing. He plans to take it somewhere and have them plot it. Does anyone know how I can change that? I went under the units menu and changed the angle dimensions to 0.0000 tolerance, but it doesn't seem to make a difference, even if I change it to degrees/minutes/seconds.
I'm not sure if the problem is in the actual line's tolerance or if the problem is in the tolerances used for dimensioning, or where to fix it?
I normally use the distance inquiry command to double check my line lengths, but I don't know how to do that to check the degrees of an angle.
Anyone that can field this one?
