Welcome any feedback.

blender version:4.2and4.3

！Current version is a test version . Use at your own risk.

！There's a possibility of crashing if ctrl+Z is used to undo actions before the curve grid is generated.

！Only regions formed by four splines will generate surfaces.

Suggest using GitHub - Shriinivas/blenderbezierutils: Blender Add-on with Bezier Utility Ops to adjust the curve.

2012.1.14-v0.3.3

bug fix

1. delete all extra materials
2. fix some errors When no object is selected

2025.1.12-v0.3.1

1. fix some bug
2. Add support for new grease pencil in blender 4.3
3. Support multiple objects to apply the grid simultaneously
4. Applying the grid will only apply the "generate_mesh" nodes, other modifiers will remain
5. Sync GeometryNodes parameters
6. Add a button to add a blank grease pencil
7. Add a button to manually simplify curves
8. Add default material
9. Fix face normal

Interface

1. Generate Curve Grid from grease pencil or Curve

   

   Merge Distance: Endpoints within this value will be merged.

   

   Auto simplify: If enabled, will automatically reduce the number of control points of the spline.Curve Control Points: Under the premise of enabling simplification, limit the maximum number of control points for a single spline.
2. New Grease Pencil

   

   New blank Grease Pencil : add a new blank Grease PencilOffset : set the offset when the stoke placement is surface

   

3. from Sharp Edges

   

   Generate curve grid from the sharp edges of the mesh.
4. Apply Mesh

   

   Convert the generated curve grid into a mesh entity, while attempting to correct face orientation and enabling automatic smooth shading.
5. Manually simplify the curve

   

   Reduce the number of curve control points
6. Mesh parameter

   

   Refer Mesh: Automatically generated, no need to modify.Simply Curve: Resample the original curve.Curve Resolution: Number of control points for the spline.try correct normal And refer: When enabled, the selected object will be used as the reference system to recalculate face orientation.Display Mesh: Whether to display the generated grid.Origin Curve: Whether to display the original curve.Resample Curve: Whether to display the resampled curve.Line width: Adjust the width of the original or resampled curve display.Merge Distance: Points closer than this distance will be merged based on distance.play: Process of generating the mesh.Speed: Speed of mesh generation.Smooth Angle: Set the angle for smooth shading.

How to use
