Export Parasolid into Inch Format
Export Parasolid into Inch Format
(OP)
Hello,
I am running NX 8.0.2.2 and I was wondering if there was any way to export parasolid out into inch format, now i've heard that parasolid was a metric conversion only, I was just wondering if what I heard was true or not. Any help would be appreciated.

As far as i know ...Yes "Parasolid files always open with metric units".You can refer to the NX documentation also for this.

Just out of curiosity a query from my side .." if you open an inch part and import parasolid in it.Then shouldn't it be as good as an inch part".Sorry if i am missing your point.

Now as far as NX is concerned, even Part files created based on Imperial units (i.e. Inch) the Parasolid data stored in those Part files will be using the Meter for the base units, however the NX software will automatically manage how this data is presented and interpreted by the UI and the downstream applications whether the Part was specified in Imperial or Metric units. This includes when data is Exported FROM or Imported INTO an existing Part file, including Importing a 'Meter-based' Parasolid model into an existing Imperial unit Part file.
As a side note, the use of the Meter as the base unit for Parasolid data was a purely arbitrary decision based on what was felt to be the most practical standard when issues of accuracy and precision using floating-point math calculations was taken into consideration. This 'standard' was first applied when the initial release of Unigraphics (AKA NX) was made which incorporated the Parasolid kernel as the solid-modeling engine. This was UG V7.0, released in 1989. Subsequent to this first commercial use of Parasolid, when it was decided to offer to other software companies licenses for the Parasolid kernel modeler, it was agreed that ALL licensees of the toolkits, as well as those organizations who adopted exchange utilities based on the published Parasolid interface standard, that they would use ONLY the Meter as the base unit. This then assured that all Parasolid transmit files could be freely shared between different vendor's software packages without there being a concern for what the actual base units of the data was. In other words, the assumption was made by ALL involved parties that ALL exported Parasolid data would use a base unit of Meter.
Anyway, I hope this clears up why there should be NO concern whatsoever over the units of a Parasolid transmit file.

You should have NO problems whatsoever Importing a Parasolid model, even if it was originally Exported from a Metric unit Part, into an existing Imperial unit Part file. Or vice versa.
Now it is true that if you were to OPEN a Parasolid transmit file DIRECTING into NX, using the File -> Open... function, then there will be NO options offered as to the base units of the Part file being created. It will always be created using Metric units.
