Having trouble making upholstery piping for cushion

icapture

Lately I have been trying to up my modeling game and find myself creating a lot of chairs. And I have run into a problem trying to get a small 1/8" pipe to run along a 1/4" 90 degree curve.

I am have tried:

using the follow me tool and a 1/4" circle. Result = no tube on edges. Tube runs fine along straight lines, but when it gets to the curve it just stops.
Lines2Tube extension. This extension got me closer, but it bugged out at the curve. The curve had a whole bunch of open areas. Not a smooth turn. I played with the "precision" number but that didn't work. Surprisingly reducing the precision made it worse. Increasing it didn't do much in terms of fixing the openings.
I also tried the extensions "pipe along path" and 3skeng 2017 pipe" none of which worked for what I need.

Obviously this is possible, I have seen it done before. Anyone have any tips they can throw my way as to a fix to this problem.

Here is a screenshot of what is happening when I run the "Lines2Tube" extension.

I will also include the .skp file in case anyone wants to take a look at it.

Scale it up then scale it back down. It will fill in the small polys

I had to increase the size X100, but it worked! Thanks a ton mate.

Very odd though that you have to work with such large sizes. You'd think a polygon is a polygon.

See this for another way.

Due to internal tolerance settings, points that are closer together than about 1/1000 of an inch are considered coincident. That can sometimes create gaps.
