Importing Step242 to UG as multiple bodies instead of compound file.

[nyang]

I have been trying to import a STEP file into NX, that contains various reference planes extracted from 3d scanned data.

When I attempt to import the file via STEP242 into an existing NX part, the features are compressed into a single "COMPOUND" feature that I am not able to make further modifications to in NX.

But when I import via STEP203 and STEP214, the features in the step file import into their respective separate bodies in NX, which is what I want.

Why is there a difference between the versions? Am I missing a parameter in my step242ug.def file that will let me import the step242 file as separate bodies? Or are there limitations to STEP242?

Never seen that before. What NX version is this ?

Try ( in Modeling) Menu- Edit- Feature- remove parameters, then select the "Compound" + OK.
it should then break the compound feature and leave "dead bodies".

The difference between AP242 and the 203/214 is ~20 years...
The 242 is a later Step version with many new features compared to the other two.
Attributes and facet data for example

Hi Tomas,

Thanks, it worked perfectly. I am running NX1980, forgot to mention that.

I was surprised to see that the step242 import behaved differently than the 203/214, I always thought that 242 version features all the best stuff from 203/214. Maybe importing bodies as one compound was a change implemented for optimization purposes, or there could be some backend parameter in my particular system that was changed without my knowledge.

Anyways, thanks again!

Btw, that Convergent Body in your file, did that import via Step 203/214 ?
I think Step 242 will import convergent bodies but not 203/214. Convergent bodies are a type of facet cloud that NX/Parasolid converts into a "Convergent body".

Hi Tomas,

I actually imported that Convergent Body from an STL file . But interesting point, I will have to test that theory out sometime.
