The image I provided here is very simple. The one's I am really interested in are of French chairs. The Thonet rocker is a classic, but I was working on a simpler "cafe" chair. It has curved braces and other things that join immediately below the seat.
So, somewhere in the process of making the parts, I got something out of line by a fraction of a degree.
I tried: Looking at the whole thing from the front view in parallel projection.
Creating a huge rectangular block that aligned with the center and "pushing" it through the contents I had already made.
I then used "intersect with model to create edges. After erasing all of the excess, I mirrored the "half chair" and "moved" everything back together.
I am getting better at this, but the parts are so close I would think they would snap together.
Thanks,
