Cyberstrak 2.1

Status: July 13, 2026


Here you can download the 2.1 version of the Cyberstrak Modeling Plugin. It runs with any 2.0 license. The installer contains as well a 30 day trial license. The version can be purchased starting immediately in our online store.


Changes and new features in the 2.1 version

General Enhancements


  • Introduction of user preferences in several commands to remember options across Rhino sessions (CSSketch,CSDynSketch, CSSymmetry)
  • Dockbar: 
    • New mode "Apply Immediately": If active in several commands a recalculation takes place immediately after change of an option (CSMatch, CSBlend, CSSymmetry).
    • Activation of the "Zebra" draw for objetcs selected in a Cyberstrak command can now be activated separately for Meshes and Surfaces.
  • Options: For the "Zebra" mode there is now an check button "Use Rhino Options". When active selected objects in Cyberstrak commands use the options from Rhinos "_Zebra" command for Zebra draw.


Modeling Enhancements


  • Surface Blend (Command CSBlend):
    • new option "Flip Edge" to invert one input Curve/Edge in case the automatic recognition of the Blend surface orientation was not giving the expected result.
    • New option "Different Lengths": When active the individual lengths between the CVs on tangent and curvature specific rows are more equally distributed depending on the distance of the input.
    • If an input edge is a so-called "Splitted Edge" the "Partial" option is activated automatically.


  •  Surface Match (command CSMatch):
    • The option "Keep Lengths" works now also for Curvature matching.


  • Surface from Curves (Command CSSrfFromCrvs):
    • New mode for triangular surface from 3 Curves (3rd input curve is splitted ion the middle)


  • Sections, Dynamic Section (commands CSSections, CSDynSection):
    • new density level "super fine" for more precise section calculations on surfaces
    • When switching between "All" and "Selected" mode the last selected surfaces are used.


  • Curvature (command CSCurvature):
    • On surfaces now both u and v iso lines can be used together als calculation base.


  • Shaded Deviation (command CSShadedDeviation):
    • new density level "super fine" for more precise calculation on surfaces.

Changes and new features in 2.0 compared to previous versions

Bug Fix Version 2.0 Revision 4156 (May 16, 2026)

Changes:


  • Surface Blend (Command CSBlend):
    • The embedded Tangency Analysis was made consistent o the CSTransition command now.
    • Fix crashes with specific input geometries.
    • Fix twisted Blend surface with specific input geometries.
  • Curve Blend (Command CSCrvBlend):
    • Improve situation, where Curve tangent was 90 degree to input Curve.
  • Surface from Curves (Command CSSrfFromCrvs):
    • If a surface edge was selected, the surface was sometimes made invisible. This has been fixed.
    • Fix crashes with specific input geometries.


Licensing and Product Structure


The licensing has been completely re-worked. In parallel to subscription licensing there is now support for Rhino Account Licensing (Cloud Zoo) or Rhino's LAN Zoo. Those License types can be perpetual (no expiration date). Also support of multiple users in one Zoo License (floating licensing) is supported. In the Dialog of the command CS_License you can switch between subscription and Zoo based licensing.


Product Structure: The Differentiation between Modeling and Reverse Engineering is given up. Cyberstrak 2.0 Modeling contains all functionality in one product. There is now also only one toolbar coming with 2.0.

General Enhancements


Dockbar: 

  • Projection Base: Here it is possible to select a Mesh. In some commands you can use it to create or modify Curve(s) or Surface(s) on top of the selected Mesh.
  • For Curves selected in a Cyberstrak command now their direction can be displayed.


Mesh Selection Dialog:

  • There is a new "Rectangle" selection mode for add and reduce Mesh faces to submesh selection.


Modeling Enhancements


CSrf4Points (new command): 


  • You can create a Surface from 4 Points. You can specify the U/V degee. In addition you create it on a selected Projection Base, in this case also the Deviation to it will be shown. The corner points can be modified dynamically.


CSSrfFromCrvs (new command):


  • You can create a Surface from 2 - 4 Edge curves. Degree and spans are taken from the curves, but it is possible to specify a Minimum U or V Degree. The Surface can be projected to the selected Projection Base, in this case also the Deviation to it will be shown.


CSSymmetry (new command):


  • A Curve End or a Surface Edge (also opposite End/Edge) can be aligned to a selected symmetry plane to make it symmetrical with a good Transition.


CSCVModeling:


  • There is a new mode "Selected CVs". Here you can restrict modeling to selected CVs, Curve Bars or CV Rows.
  • The Projection Base is supported now, the selected Curve or Surface is always dynamically projected to it.


CSSketch/CSDynSketch: 


  • The curve sketching can now create curves projected to the selected Projection Base.


CSCrvRefit:


  • This command has been enhanced by a mode to take over parametrization from a Reference Curve. Also dynamic Change of the parametrization with more weight to begin or end of the curve is possible now.  An embedded Curvature Analysis is now avlaible.


CSMatch:


  • There is a new mode "Keep Lengths" for Surface matching. At the moment it has only effect for Tangency matching, not really for Curvature Matching.


CSTransition:

  • It is now possible to analyse the transition of a surface edge to the interior area of a reference surface.


CSDeviation: 


  • An "Auto Scale" button has been introduced.
  • In addition it is possible to move a dynamic position handle across the selected object to investigate local deviation on any point.
