I’ve been working on making a tool for myself, it just does a couple of random helpful things. My favorite is the create primitive tool. My tool comes with a bunch of helpful objects that Unity doesn’t have. Its really nice because I don’t have to go into my 3d software and export an fbx just because I need a pyramid! The tool also has the default Unity primitives, which basically means you can make primitives way faster compared to using the Menu and clicking on GameObject/CreateOther?Object… There also a Zero Out Position and Zero Out Rotation Button. Those buttons were easy to make and mildly helpful so I threw them in. If people think it would be helpful, I’ll try and put it on the asset store. I’m pretty new to coding so I can’t do anything really advanced, but I am totally up for adding simple features that people request. I probably won’t be able to do most of them, because like I said, I’m pretty new to coding. Leave a comment and tell me what you think! 
I went on the asset store and didn’t see any assets that were free and made using primitives easy
I think a having a better primitive creation tool for rapid prototyping has always been a fairly popular request for Unity, and I could definitely see myself using something like that, especially if the primitives are easy to modify (pull/push vertices even?)
Yeah I’d love that too! I’ll see if I can figure out the sculpting part although i think I can guarantee that’ll be really hard. Putting primitives in however is very easy. If there are any shapes or meshes you think would be nice lemme know and I’ll through it in. Right now I’ve got a bunch of new ones. The obvious stuff like pyramids and tubes are in there.
