The Building Support sub-category is intended for all development support relating to architecture on the Roblox platform. This includes questions ranging in difficulty from extremely basic to even the most technical of issues.
You may present your thread how you choose, but you are required to answer the following questions in your thread;
What are you attempting to achieve? (Keep it simple and clear)
Making the corners or bevels, like in a stud way.
What is the issue? (Keep it simple and clear - Include
screenshots/videos/GIFs if possible)
I know this might sound like I am dumb but I have no idea how to make it.
What solutions have you tried so far? (Have you searched for solutions through the Roblox Wiki yet?)
These are made with wedges. The more wedges you have the the more it will circle out. You can inset a wedge into your place using the part dropdown.
As seen here:
You’re going to need to rotate the wedge so its flat, and then you can place it between two parts.
As @Crazedbrick1 mentioned, you can also use unions. I would’nt recommend this, but it will create the same affect. You need to use a part that you want the rest of the parts to negate through.
