Hi, its pretty simple once you figure out how it works. You have to draw a circle, then from the center point draw a line and drag using the pull tool along the line.
Here is an example:
First the circle and line is drawn:
then you select the tool
Then with the tool click on the cicle:
Pull it along the line:
Carry on downwards, and it draws the pipe
Off course you can draw the line in any shape you want, you can use the round tool to make perfect round turns on pipes. Just make sure you draw the entire line of the pipe you want to use before you pull it.
I will get back to it thats for sure, but there are other priorities at the moment.
So this might be on hold for a while still life is a b**** sometimes!
