nTopology 3.0 - What's New

Version 3.0

nTopology 3.0 is here! nTopology is now even faster with GPU acceleration. This new GPU-powered computational framework creates geometry previews 10x to 100x faster than our traditional nTop rendering technology. Additionally, when you open the software, you will now see a new Home Screen that gives you access to example files and learning resources. Lastly, we’ve introduced the ability to instantly access nTopology by creating an nTop account in two different ways. You can now download and install an interactive preview of nTopology, which lets you open, view, and interact with nTop files. Or you can choose to experience the full functionality of nTopology through a 14-day trial. As with every release, nTopology’s dedicated support team is ready to answer your questions. Please visit support.ntopology.com to gain access to helpful tutorials and support articles.

Home Screen

  • nTopology now features a Home Screen, which provides you with access to example application files and learning resources.
  • By default, nTopology will open to this Home screen. You can change this by going to File > Settings > General and check “Skip home screen on startup.”


GPU Acceleration (beta)

  • nTopology 3.0 includes the beginning of a new, GPU-powered computational framework that creates geometry previews faster than ever before.
  • A new UI control allows real-time edits to any Scalar value using your mouse. For many nTop models, editing these values produces dynamic graphical feedback.
  • The acceleration should be 10x-100x faster than the traditional nTop rendering technology.
  • By default, this feature is currently turned off. To turn GPU acceleration on, go to File > Settings > General and check the “Enable GPU Acceleration” checkbox.
  • CAD parts, meshes, lattices, and most implicit modeling and field-modifying blocks, support real-time modeling in nTopology. Over the coming months, we expect to accelerate more features such as Voxel Grids, primitives, and smoothened implicits.

Get a Preview of nTopology

  • We’ve introduced a new preview version of nTopology that gives you the ability to experience the capabilities of nTopology, without needing to have a trial or a full license.
  • This preview of nTopology allows you to explore and interact with exciting nTop application files without learning our software’s full authoring capabilities.
  • With this preview of nTopology, you can open, view, and interact with files through variables in the Input section of a Notebook. You cannot add blocks, delete blocks, modify notebooks, export models or data, or save files in this preview of nTopology.
  • To access this preview of nTopology, visit app.ntopology.com/signup and create an account. Once your account has been set up, you’ll get instant access to nTopology and other learning resources.
  • If you already have an nTopology license, you won’t be able to experience this preview version until your current license expires.
  • When your license expires, nTopology will revert to this preview version, so you’ll still have the ability to open, view, and interact with all of your nTop files. To purchase a new license, contact sales@ntopology.com
  • Do you have a colleague or friend who would get value out of using nTopology? Send them to app.ntopology.com/signup to get started with nTopology today.


14-Day Trials

  • We’re now giving you the ability to access a trial of nTopology.
  • This trial license is a full functionality 14-day license, which, when it expires, will revert nTopology back into a preview version.
  • To activate your 14-day trial, select the Activate Trial button in the top right corner of the user interface of nTopology or visit your account at app.ntopology.com and select the Activate Trial button located underneath the Let’s Talk button on the Home page.
  • Note: If you have a full license of nTopology, you will not have the ability to access this 14-day trial.


New Lattice Pipeline Enhancements

  • The Periodic Lattice Body block (beta) has been updated to include new overloads for new unit cell types that indicate the number of free parameters the unit cell has. For example: Unit Cell <0>, Unit Cell <1>, Unit Cell <2>.
  • The Custom Implicit Unit Cell block (beta) has been deprecated, and a newer block with the same name (also in beta) has replaced it.
  • The new Custom Implicit Unit Cell block outputs a Unit Cell <0> indicating that it does not have any free parameters. When used as the unit cell input of the Periodic Lattice Body block (beta), it triggers the Unit Cell <0> overload.
  • We introduced a new block named TPMS Unit Cell with Bias (beta), which outputs a Unit Cell <2> indicating that it has two free parameters (approximate thickness and approximate bias length. When used as the unit cell input of the Periodic Lattice Body block (beta), it triggers the Unit Cell <2> overload. Below is an outline of the new block:
    • Block Name: TPMS Unit Cell with Bias (beta)
    • Location: Beta > Lattice - Unit Cells
    • Description: Select a unit cell from a library of TPMS unit cells with 2 free parameters. Parameter 1: Approximate thickness - Approximate thickness of the TPMS walls. Parameter 2: Approximate bias length - Approximate bias of the TPMS as a negative or positive approximate distance. This will shift the outer wall inward or outward.
    • Input 01: Unit cell
      • Type: TPMS Enum
      • Description: The selected unit cell for the lattice generation workflow.
    • Output: Unit Cell <2>
  • The Orient Unit Cell block has been updated to include overloads for the new unit cell types.

Usage Improvements

  • Every object in nTopology now auto-converts to a list of 1.
  • The Filter Mesh by Flood Fill block has moved from Beta to Production
  • We’ve updated the name of our software product from nTop Platform to nTopology.

Bug Fixes

  • We’ve resolved an issue where removing an Implicit Body from a Variable was causing the visualization to permanently disappear.
  • We’ve resolved an issue where the Voxel Grid from Mesh block was not voxelizing surface boundaries of cavities or voids in shelled bodies.
  • We’ve resolved an issue where visualization would stop working when a block was made a variable and then undone (ctrl-z).
  • We’ve resolved an issue where hidden objects were becoming visible and couldn’t be hidden again.
  • When viewing an implicit body list, changing the resolution now updates the visualization.
