So I’m making this curv for a road and I have decending bricks going around in a circle with a wedge ontop. But there is an issue when you see the curv from another angle, and it does not look smooth.
So my question is what can I do in order to make the inside look better/smoother? any methode with the use of union, triangle draw or should I just go for gapfill instead?
Gap-fill will not work in this case. Using parts to achieve this shape just isn’t practical, and you won’t get the results you are after.
I would suggest importing the start and end of the curve to blender, create the curve there, and then import it back into studio. The positional data will be maintained, so when the mesh is inserted, it will be in the right place already. ( If the positional data is wrong, negate the values. )
There are some imperfections on the sides left over after the main gapfill, but they’re large enough to gapfill once more which then results in a clean finish.
The reason that you’re having so much trouble, by the way, is that there is no “clean” way to fill in this shape (a screw) with parts. Doubly gapfilling as mentioned above is the best you can do to construct it because you need two separate parts for the top surface and side. The angle between the surface of the screw and the side of the screw isn’t exactly 90 degrees if you fill the top with two triangles.
Cutting out the center using negative geometry won’t help. You’ll have to actually cut both the inside and the outside of the shape using negative geometry to construct it any more easily using CSG (Single gapfill the top surfaces at a wider width than you need and then trim the whole thing at the sides with CSG).
