curves in renders

I understand how to use the pen tool to a point but one thing that i do not understand is how to do curving....i can make plenty of little striaght lines that make it look curved but it isn't curved. So if there is a tut out there that shows how to do this could someone post it. other question is.....do you have to use something other than the pen tool to do curves? Thanks

check my pen tool tut in the tutorial section its the same basic concept.

Also, you can alt+click to move the outer points so you can recurve your line.

main thing to remember is ctrl+click

so core says alt+click and you say control+click....which one and when you say click you mean my mouse?

heh, its Alt + clicking the left button on your mouse

thanks myth

really i jsut have to hold my mouse button down while i do it
