The image shows the corner section of a rectangular fence where it bends. I want to create a smooth, rounded transition at the corners, as indicated by the red marking in the image. Is there a way to achieve this in Shapr3D?

One way would be clever sketching on a single plane and rotating radius segments.

> You simply need to create one side and mirror the other. Try this: Draw a circle. Use the “move tool” to move and make copies of the circle using the (+). Move and rotate the circles in a half hazard arc. Then use the loft tool to loft from circle to circle. Also try this: draw a flat line with 2 lines and 2 arcs kinda like a handlebar. Using the move tool, move the anchor point to where the lines connect and rotate to make the flat line twist into 3d space.

Hi,

I would project an arc of a circle on the surface of a portion of a sphere and then sweep along it. By doing so, you will get good curvature continuity because the sweep will be on the surface of the sphere and you can edit the 3D curve simply by editing the circle.

The video shows the simple process of doing it.
