Hi all. I've searched the WWW, and it doesn't seem that there is an easy way of doing this. Do you have any experience with this? Thanks in advance. Niles.

Just for fun, thought I’d throw this out for discussion. What do you think is the best way to call out an SAE straight thread port on a drawing? For example, you could call out all the individual dimensions so that every machine shop would be able to machine it even if they’re not familiar...

Draw a graphic of the function using the basic elementary functions. For example. Draw f(x)=\frac{1}{x-1}-1. I know that I will first draw the function 1/x (basic function) then shift the graph of the function 1/x for 1 on right of the x-axis, so I got the graph of the function 1/(x-1). Then...
