OK… I’m new to these drawing programs, so there’s that issue… and I was expecting to be able to hit exactly 1/4". The closest I seem to be able to get the circle is 25.17 and when I put it over the top of your circle, it is a little bigger and I’m able to eyeball it into place, but so far I don’t see any place to actually adjust sizes by typing in numbers. I’m OK with that because I make my own dowels on the table saw and they tend to be a bit over 1/4". But in order to see through the circle, I had to adjust the background color because they were bright red. I also adjusted the outer line to look about the same as yours. Now if I try to draw another circle, nothing shows. Obviously I changed something. I guess I’m going to have to read the Inkscape material to figure out what the heck I’m doing wrong. Until then I’m thinking of copy paste the circle I was able to make and run a part and see what happens.
