For a long time we faced the problem of creating flexible shapes in blender and other 3d modeling programs, many programs give a convenient interface and a beautiful picture, but when the result of curvilinear models is converted into a mesh, we had to do a lot of routine to bring it all into a working form, it was either a triangulated mesh, or a lot of polygons, improper shading and much more.   

Expert Curve Modeling is a powerful tool that allows you to create complex and flexible models using  Bezier curves. You get the ability to control the mesh both on the whole model and on its individual parts.
Created 4 modes of vertex, curves, segments, models control. Each mode has its own set of functions, we also added pop-up menu hotkeys (we tried to make them intuitively memorable similar to the hotkeys of blender, for faster getting used to the add-on), more details about everything in the documentation. 

You will be able to create organic forms (plants and animals), various abstract objects of complex shapes while maintaining the correctness of the topological mesh, conceptual designs and much more. The demo video shows the models made by our add-on and their topology.

This add-on is in beta testing stage (We look forward to your support)

Preview video

I show a few models that we managed to make during testing, more here

Actually what we plan to want and plan to add in the future

-Loop segments or Knife segment
-Subdivide segments
-Extrude triangle and segment
-Ngon segments, Extension of segment types and Segment topology
-Boolean operation
-Offset
-Asset import
-Extension of select functions
-Combining several segments into one
-Segment mirror
-Merge variation extension
-Creating multiple parallel models
-Segment drawing
-Bevel Segment

If you also have ideas for features that would greatly improve the modeling process with this add-on be sure to let me know, if possible we will try to include them in this list

Instructions and videos on working with the addon will be located in the documentation section

Update 2.1.6
Added Mesh to ECM (Mesh to Vertex, Curve, Segment ECM) conversion function. 
Update 2.0.4
-Performance optimization when the number of segments is significantly increased. It is very important not to use the new version of the addon on older ECM models, I have built a new data transfer algorithm into each function.
-Manual resolution has also been finalized, no longer needing to hold down the alt key, and the ability to manually resolve on triangular segments has been added
-The duplicate and separate functions have received an improved version for use with hotkeys
Update 1.7.6-1.8.2
-Major bug fixes
-Button “update origin” (now if you select the desired object (Curve or Segment) it will be executed only on them, without selected objects it will be executed on all ECM objects.
