[ This feature has been updated for prototype users]
A new feature coming next is 2D SDF Group which was originally proposed for a 2d sdf editor.
It allows users to combine primitives in 2D space, and then extrude the compound shape just as the basic profile shapes.
Bevel/Hole/Cone can also be applied to 2D Groups.

2025-07-12 05:29:15 +0000 UTC View PostOne issue of the current camera system is that the camera is always rotated around the global gravity direction. It's not convenient when you want to edit shapes in its own space (e.g., editing points in a rotated Bezier shape or editing strokes in a rotated object).
Therefore, I added a new camera button besides the recenter camera button to reorient the camera to the lo...

Each group has its own local coordinate for mirroring and pivoting.

In the next update of this month:
Round and Shell properties are added to Subgroups.
Hole, Shell and Cone properties are added to Character and Polygon primitives.
These improvements will allow to create more complex hard surfaces.
A new helix type will be added in the next update.
In the previous version, the helix profile is extruded along a spiral path.
Now, the helix profile can be extruded along the z axis.
It' useful to create shapes like drills and pillars.

this primitive is expensive to evaluate, so you may limit the number of helix primitives or use small blending fact...

I've done some preliminary work on the live SDF operations on mesh primitives recently.

Since we already have a bunch of 2D graphic primitives in the toolbox, how about developing a vector graphics editor as well?
Early tests showed some promising results, though there are lots of unsolved issues (especially with soft blending and anti-aliasing), and the SDF method doesn't show too many advantages over traditional SVG methods (performance, effects, etc.).
But maybe, it...
