General Usage Instructions

Para 3d offers full functionality in our trial version as our commercial license. The demo, however, prohibits the re-opening of Paraflows (Para 3d nodes and relationships) and is valid for 30 days from the date of installation.

Please visit us at here for tutorial and learning tools.





If Para3d V2.0 (or higher) is installed, run the uninstaller from the start menu. You may
have installed older versions of Para3d with multiple versions of 3ds Max. In this case, the
uninstaller will recognize the most recent installation. You would then need to manually
uninstall all other Para3d versions by removing the associated files from the startup folder.
Please refer to the list below :

  1. MAX folder\script\para3D(folder)
  2. MAX folder\script\startup\para_logo
  3. MAX folder\script\startup\
  4. Open 3ds MAX and remove all user interface items for the associated version

Para 3d toolbars will be automatically installed. In case of any problem during installation please
follow this tutorial :

Additional Information

Important Notes:

Installing Para3d requires your agreement with our user license which has been provided to you in the installation wizard, please read the agreement carefully before installation.

Para3d V4.0 does not support earlier ParaFlow files. Files created prior to V4 will open but may be unstable.

Thank you and happy designing!

Version History

Version Number Version Description

ver 5.0

In this version we ensured the compatibility of Para 3D with 3DS MAX 2021. Here is short list of new features and fixes: Bugs fixed Controller parameters were not visible in previous release. This issue is fixed now in Min Max parameters in Bitmap Controller Initial value in Transform controller Parameters of Intersection controller Parameters of L-System controller Controller channel in Offset controller Output parameters in Polyline controller Error in updating Para-Shape node in 3DS MAX 2020 Bug in trainagulation function of Edit Poly node has been fixed now. All traingles are created in the same size In vector controller Bug in Construction of plane with point and normal is fixed. In vector controller Bug in reporting co-planar vectors is fixed New features Mesh subdivision and smoothing is now added to the Edit poly node. Link controller can now be used with Edit poly node. This provides access to the information of editable poly object which is being modified by Edit Poly Node. Enable construction of XY,YZ and ZX plane at given point. The value types of Object and Ray could now be converted into String type using Text controller.

ver 4.95

Para 3d Version 4.95 release date: 10-November-2018 Compatibility upgrade to 3DS MAX 2019 See previous changes in Para 3d 4.9

ver 4.93

Para 3d Version 4.93 release date: 7-June-2017 New feature "Non selected" option has been added to Para Edit poly sub-object selection methods. Using Test controller you can check if a list contains a float number or not. User can control the precision in Curve controller. Enable modifier options has been added to reference arrays (Parametric Array). Integer only option has been added to random controller to generate random integer numbers. Improvements Bug fixed reloading the magnet controller settings Bug fixed in saving the point positions in Graph controller. In Mesh controller the outgoing edges of a vertex are computed as outward vectors (unified direction) In Mesh controller the length/width and height of the local bounding box is corrected. In Mesh controller The bisector of vertices of a face are now returned in order. Bug fixed in reverse array functionality in Array variable controller. Various bugs fixed in Para EditPoly bug fixed in displaying values (spinners) in controller settings (3ds Max 2017 & 2108) Bug in Graph controller and Magnet controller display is fixed Bug in adding attributes to Parametric Array is fixed Bug in transferring controllers from old array to new array is fixed Vertex normal method in Mesh controller returns the true normal if edit poly method selected. See previous changes in Para 3d 4.9

ver 4.9

Para 3d Version 4.9 release date: 11-Feb-2017 You must uninstall older version of Para3d before installing this package. New feature Brand new graph controller.
