Sometimes this game is really really really really frustrating. The only way to generate curves is to make a flower pattern with beams inlaid into themselves and change angles. Then you have to add another piece of textured wood on the edge to attach your circle parts. But sometimes beams and planks and logs not even at all will ghost into the previous drop even without touching the mouse.. if you accidently move the mouse you are done and you can never get back into. Either it works from the beginning or your doomed to hours of frustration.
What needs to be put in will someday I am sure but maybe something that could force the beams to align inside themselves like a spot on them that helps you align the mouse so they do.
It seems to me we could save huge issues in rendering in this game if everyone was able to build curves without thousand and I mean thousands of vertical small segments. I looked at the little row boat someone did and there were over 100 items just to generate an oar. There were 6 or so ores in the blueprint. The ropes and other things had huge numbers of vertical items. The hull was hundreds and hundreds more items. This must bring some computers to their knees especially at the high pings people in Europe or Australia want to play on US servers. This is probably one of the biggest reasons people give up on this game.
