Version 1.3

Status: January 29, 2024


In the meanwhile we received much more user feedback. This has been adressed with the update version 1.3 available for download now. The update version works with the same license as version 1.0. Information about previous versions you will find below.


Changes in version 1.3:


  • General:
    • Improve display of vector/tangent handles, especially in central perspective. Fix potential display crashes when handles got very big or very small.
    • Sometimes active Cyberstrak dialogs disappear when minimizing/maximizing Rhino. If the command is re-started, the dialogs show up now in the current working state again.
  • New command Curve Blend (CSCrvBlend):
    • Can be activated as usual via command line or Pull Down menu. On the Modeling toolbar it can be activated via right Mouse click on existing Blend Icon. Works similar to Surface Blend.
  • Surface Blend (command CSBlend):
    • Add option "Partial": Allows to shrink the input edge(s). New domain handles have replaced the handles of earlier versions.
    • Add option "Shrink Surface": Allows to shrink the input surface(s) dynamically via domain handle on isoline parallel to surface edge.
    • Add option "Invert": Allows to reverse the tangent direction of the Blend surface.
  • Matching (command CSMatch):
    • Add option "Partial": Allows to dynamically shrink the input edge via domain handles.
    • Add option "Invert": Allows to reverse the tangent direction of the modified object.
  • Transition (command CSTransition):
    • Add option "Invert Direction" to flip Tangent or Curvature graph on coresponding surface edges.
    • Fix cases, where normal/tangent angle difference was shown incorrectly.

Version 1.2

Status: December 21, 2023


In the meanwhile we received much more user feedback. This has been adressed with the update version 1.2 available for download now. The update version works with the same license as version 1.0. Information about previous versions you will find below.


Changes in version 1.2:


  • General:
    • Cyberstrak Handles are set now inactive during Rhino navigation via right mouse button.
    • Installer: Uninstaller shows now also name and version of product to find it easier for de-installation, especially on Windows 11.
  • Dockbar (command CSDockbar):
    • Do not show it at first PlugIn startup. To get it please use the command CSDockbar. When closed, do not show it as default in the next Rhino session. 
  • Blend (command CSBlend):
    • Do not reset modified tangent row lengths after moving partial handles or Apply.
    • Fix some constellations where twisted surfaces were created.
  • Curvature Analysis (command CSCurvature):
    • Allow bigger scale factors for curvature graphs to support also graphs on geometry with much bigger curvature radius.
  • Sections, Dynamic Sections (Commands CSSections, CSDynSection):
    • Allow bigger scale factors for curvature graphs on sections.
    • Density parameter also works for Subds now.
  • Shaded Deviation (command CSShadedDeviation):
    • Change color range to support negative (blue) and positive (red) deviation distances.
    • Filter: Min and Max default values will be taken from last calculation.
    • Allow Subds as reference in Rhino 8 version.
  • Deviation (command CSDeviation):
    • Allow Subds as reference in Rhino 8 version.

Version 1.1

Status: December 10, 2023


In the meanwhile we recived first user feedback. This has been adressed with the update version 1.1 available for download now. The update version works with the same license as version 1.0. Information about 1.0 you will find below.


Changes in version 1.1:


  • There is a special display variant that changes the object appearance optimized for the work with the Cyberstrak commands. This variant caused some graphics performance issues especially when a large number of objects had to be drawn (mainly Curves). That happened also, when the variant was not activated. This has been fixed now.
  • Surface Blend (Command CSBlend): If the selected input surfaces were planar or had degree 1 in cross direction sometimes a wrong or even no result surface had been created. This is fixed with the new version.
  • Transition Analysis (Command CSTransition): If matching/transition quality between corresponding surface edges of planar or degree 1 surfaces was investigated, sometimes the result of tangent or curvature deviation was displayed as 90.0 or 180.0 degree, even when the real result was 0.0. This was also corrected.

Version 1.0

Status: December 4, 2023


In the download area you can find 2 versions of the Cyberstrak PlugIn: A version for Rhinoceros 7 and for Rhinoceros 8. To install one of them you need to have the appropriate Rhino versions installed.


Information about the installation of the downloaded file and the activation from trial mode into a commercial version you can find on our support site.


The PlugIn contains 2 products:

  • "Cyberstrak Modeling":  This product contains commandsfor the analysis, creation and modeling of Curves and Surfaces.
  • "Mesh Tools and Reverse Engineering": Here you will find commands for structuring and smoothing of meshes and mesh areas. Also a command to create theory surfaces on top of mesh areas is available. All functionalities of the product "Cyberstrak Modeling" are included.


The product contains a context sensitive online manual which helps you to understand the functionality.
