Siemens NX – Renew Feature and Update Feature

Renew Feature vs Update Feature

There are two commands in NX as ‘Update Feature’ and ‘Renew Feature’. It is important to know the difference between these two commands and which one to use and when?

NX – Difference between NX Update Feature and Renew Feature

Update Feature just performs updates and recreates feature using NX feature code of version in which it was created.

Introduced in NX 11, Renew Feature also perform updates, but it is not same as update feature, It recreates a feature using the feature code of the currently running version of NX.

As of now (NX 1847 or 1851), Renew feature does not support features created in earlier version of NX 8.

Also, it does not support all the features. Following are the list of features that can be updated using ‘Renew Feature’

  • Edge Blend
  • Offset Curve in Face
  • Trim Body
  • Face Blend
  • Offset Surface
  • Blend Corner
  • Intersection Curve
  • Thicken
  • Draft Body
  • Law Extension

  • Fill Surface

NX – Renew Feature Command

All features can be edited and updated in the latest version of NX without renewing them.

It is not compulsory to use ‘Renew Feature’ as global use
or when you move to new version of NX. It is supposed to be used part by part, feature by feature basis.

Performing a renew feature can occasionally cause changes to geometry so it is best to perform the renew on specific features only when needed.

With several enhancements in NX, Some features have new options added that require a renew to access. Using the renew operation simplifies the process so the user no longer has to recreate, replace and delete the original feature.Siemens NX – Renew Feature command icon
