Question about the 500 Meter Limit on NX .PRT Files - Limit only for Components, or Assemblies to?
(OP)
This is a question that is bubbling up pretty fast on a project that I am working on, and a definite answer is needed:
NX .prt files have a "1 Km Limit" which for all practical purposes equals to a 500 meter limit on the Positive X, Y, and Z Axis. Is that limit only for designing physical components (like say a tunnel), or does it also apply to a virtual assembly that could be Km in length, width, and depth?
It would be a bonus if anyone can point to me where at Siemens websites the definite answer is published. Thanks in advance for the answers

RE: Question about the 500 Meter Limit on NX .PRT Files - Limit only for Components, or Assemblies to?
As for your initial question, this is primarily an issue with respect to the Solid and Surface modeling data of the Master Part models and not necessarily Assemblies, although there are some considerations there as well. Note that in the case of Assemblies, generally the first issue that one encounters is how the Assembly is displayed. Note that there are some things that can be done to mitigate those issues but it only impacts how geometry is displayed not how accurate or precise that geometric data is being represented or manipulated.

Variable to add to or edit in UGII Environment Variables: UGII_MAX_FIT_BOX_SIZE
Increase the Variable to be able to pick what you need in your assemblies and/or drawings.
