Installation

The zip-file contains the addon that has to be installed in the Blender Preferences (Edit -> Preferences). Click the button Install... and select the zip-file in the opened file dialog. After installing the addon a panel JCurve is added to the sidebar (open by pressing the N key).

Usage

The addon has two main features:

1. Curve Creator

With this tool you can enter a Creation Mode for curves in which you can click onto mesh to define points for the curve. The curve can be created then by pressing the Enter key. For the curve the depth of the bevel can be defined before it is created.

Just Ctrl + Click onto the mesh to set the points, when you press the Enter key a path is created, when pressing Ctrl + Enter a Bezier Curve is created and the points snapped to faces of the underlying mesh (perpendicular).

2. Curve & Mesh Tools

With these tools meshes can be assigned to curves easily. Just select a Mesh and an arbitrary number of curves and press the Create button. The mesh is duplicated then and assigned to each selected curve.

Here can see the assignment process. First the curve and mesh is selected:

And after pressing the Create button, the mesh is assigned. 

Then you can define how the mesh should fit the curve: Fixed Length, Fixed Count or Fit the length of the curve.

Also an Offset between the mesh-parts can be defined.
