Michael:

Many thanks. No worries. There is plenty to learn in the meantime, but I now look forward to this new Mac version!

Since this question on the controls though another one has popped up, and now I am not sure whether my difficulties with a particular command may also be due to this Mac version.

I am have been trying out the sweep command. Easy to create a circle perpendicular to the end of a line and then create a tube. But I wish to sweep a half circle along a path. I imagine that the first step is to draw a semi circle using the arc command, connect the ends and sweep that. But there seems no way to draw the arc perpendicular to the end of the circle, i.e. there is no 'vertical option' as there is for the drawing of a circle. I did look at a a couple of videos on YouTube, helpful, but did not answer that specific point. This is more than an exercise; we will want to use this specific command to create a sundial to be carved out of metal using a CNC machine.

Perhaps you might point me to something that speaks to this?

Thanks again

Andrew
