"Follow me" tool not giving the wanted result

[mygis]

Hello,
I am new in Skecthup and I have to learn how to design a spring. I followed a few tutorials online and they work fine for me. After designing the spring I had to make it thicker but I have faced two problems:

1. The thickness required is 1.6 mm for the galvanized wire so I used a radius of 0.8 mm to create a circle to be used for the follow me tool. However SU returns with an error saying that the value was too small.
2. I have merged all the lines using the welding extension and managed to use the Follow Me tool, however not all th segments are covered.

My questions:

1. Can I use a value below 1 mm if the template used is based on mm? (I am using construction documentation millimeter template)
2. Where should I start from to troubleshoot this problem with the follow me tool (or my design)?

Thank you in advance.
Lyes

You need to work at a larger scale due to the fact SketchUp won’t create those tiny faces. Use the “Dave Method” which you can find described if you search the forum to make a component and scale up a copy of it to edit.
