nTop 5.24 is here! This release features new modeling blocks, allowing more nTop modeling and enabling iteration of an entire design space. As with every release, nTop's dedicated support team is ready to answer your questions. Please visit support.ntop.com to gain access to helpful tutorials and support articles.

Implicit Body from Surface

  • The Implicit Body from Surface block creates an implicit body from a surface with the zero-surface extending tangentially at the boundary.
  • Block Name: Implicit Body from Surface
  • Location: Utilities > Conversion
    • Surface: CAD Body, Mesh
    • Tolerance: Tolerance of conversion determined by the distance of the resultant Implicit Body to the surface of the CAD Body.
    • Output: Implicit body
      Implicit Body from Surface

Implicit Body from Surface Boundary

  • The Implicit Body from Surface Boundary block creates an Implicit Body with the zero-surface extending orthogonally at a surface boundary.
  • Block Name: Implicit Body from Surface Boundary
  • Location: Utilities > Conversion
    • Surface: CAD Body, Mesh
    • Tolerance: Tolerance of conversion determined by the distance of the resultant Implicit Body to the surface of the CAD Body.
    • Output: Implicit Body
      Implicit Body from Surface Boundary

Evaluate Surface

  • The Evaluate Surface block creates a point at the corresponding U and V coordinates intrinsic to a CAD surface.
  • The Evaluate Surface block can be used for Flow applications, detailed rib design to locate points based on U and V coordinates.
  • Block Name: Evaluate Surface
  • Location: Utilities > Evaluate Surface
    • Surface: Surface to evaluate.
    • U: U parameter to evaluate. This value will be clamped to the range [0,1].
    • V: V parameter to evaluate. This value will be clamped to the range [0,1].
    • Output: Point
      Evaluate Surface

Distance to Curve from Axis

  • The Distance to Curve from Axis block computes the signed distance from a planar curve to an axis. The curve must behave like a function relative to the axis, meaning it has exactly one output distance for each input along the axis.
  • The Distance to Curve from Axis block can be used for generating variable offset fields and creating directional parameterization fields.
  • Block Name: Distance to Curve from Axis
  • Location: Modeling > Evaluation
    • Curve: The input 3D curve (must be planar with the axis).
    • Axis: The axis to measure distance to. Encapsulates origin and direction.
    • Direction: The direction along which to measure the distance.
    • Output: Scalar Field
      Distance to Curve from Axis

Usage Improvements

  • We have added the ability to right-click on point and vector inputs to convert them into blocks quickly The converted block will retain existing inputs, including properties.
  • We have added Right-click on list inputs to easily add and rearrange list items.
    Right Click Improvements
  • We have moved the Light mode out of Beta into Production.

Block Updates

  • We have updated the Extrude Profile block to add a shelled extrusion overload.
  • We have updated the Shell block to support a scalar field thickness value.
  • We have updated the Twist block to support a scalar field twist rate value.
  • We have updated the Curves property on the Slice type to Polycurve.
    • Note: For backward compatibility, a block will be inserted into the notebook where the Curves property was previously used.

Bug Fixes

  • We fixed an issue with the Split Mesh block that caused empty meshes to be returned in some rare cases.
