Many thanks for those tips. I have practiced, and they work!

Now I have just made my first fluted column too. I was hoping that I could do it using the protractor, knowing how many degrees for a 6 flute column, but I found that there was no indication of how many degrees the protractor was extending (strange for a protractor), but I did it by setting the circumference snap to multiples of 15 degrees, and finding the appropriate green dot along the circumference.

I did it using this procedure:

1. Draw a circle 8m diameter (4m radius)

2. Pull it up to 50m height (this is for a skycity column, the flutes will carry the glass elevators)

3. Draw another circle inside it, of 5m diameter, same centre (using the methods above), and push that circle out to form a cylinder.

4. Draw six circles of 2m diameter, spaced at 60 deg apart, and with their centres on the circumference of the large circle. Delete the part of the circumference of these small circles outside of the large circle.

5. Select the part of the small circle that is inside the large circle and pull each of the six all the way down, to form the flutes.

Done

Hi,

Very noob question!!

I can create a circle, and using the push-pull tool I can extrude it into a cylinder.

I now wish to make it hollow, like a pipe or tube

I want to draw another circle on the original circle, then use the push-pull tool to create the pipe

The problem is, getting the centre of the second circle aligned with the centre of the first circle

How is this done (in nice easy steps please)
