A way to make holes and concave cuts has been requested a lot, and there are quite a few challenges involved there, technically. Hinges are also a commonly requested feature, which have their own challenges too.

yeah, I figured that. Is there a way to integrate the mechanic of how the saw fits into the jig slots with the dowels so that when you make a hole you are basically doing the same, although i realize by doing that it may make it impossible to allow the dowel to spin. Hmm yeah I understand, this may be too difficult to solve. what about a way to make it so that the dowels don't mesh through player made square holes as easy?

The problem that I continually run into with new features like what you are describing are the special cases. It's easy to think of the basic rules for a new game mechanic, but there are so many special cases to sort out that it makes things quite difficult to design with a high success rate for most players.

The instability with the dowels and square holes is mostly a stability problem associated with mesh colliders. There are mesh colliders on the wood and dowels because simple colliders (sphere, capsule, box) cannot be used because the player can slice and dice them, so they need to be dynamic. Mesh colliders create a far greater penetration compute problem than simple colliders, so that is why there is more instability. This is why in most physics games, you are only allowed to smash together pre-defined objects of known dimensions, usually using a combination of simple colliders.

I don't mean to sound too negative, because I do appreciate your feedback and ideas! I just get frustrated because they would be really cool to build, but there are some major roadblocks.

I've been following the items you've been sharing on the workshop and am impressed with your creativity!

thank you, I appreciate everything you have said. I am definitely not discouraged. in fact I am starting out as a game developer my self, and I obviously dont have as much experience as you. So knowing this sort of information is very helpful to me in the future. I like solving problems and am trying to learn more about coding so I can figure out possible work a rounds in games, whenever I run into a problem in one of my own future game developments. I think your game is great already. Its my job as a player to keep testing and figure out stuff.

Thank you for following, I love building things in irl and this program saves me money in materials so i can test out ideas.

Good luck! You are curious and on the right track. I'm happy to help where I can.
