Hello
I'm asking for your help because I have a bug when opening a STEP file.
Indeed, when I open it in SOLIDWORKS I am missing part of the model but when I open it in E-Drawing, I have my complete assembly:
I won't explain it, if you have any ideas I'm all for it.
I'm attaching the original file if you ever want to test on your side.
Thank you in advance.

One explanation would be an identical filename for 2 different parts.
Under other software name d2 part can be identical. Under solidworks, once the 1st part is opened, the 2nd part of the same name will be automatically replaced by the 1st. Hence probably the disappearance of the 2nd.
A solution to rename the identical parts with different names before export.
After opening it seems that it is rather the room itself that is the problem, since it only keeps a small part of the room.
Maybe in another format this piece will be better recovered.
Bugs of this style sometimes occur during conversions from one format to another (especially on surface)
Hello
Glitch-free opening visible with SW2024, all the elements seem to be present.
I did a step for you again...

You never know, on a misunderstanding it can work 
Hello
No problems with opening under SW2020 either.
maybe it comes from your import settings on SW?
Hello @a.eriaud ,
Your manipulation worked because I have the complete model with your WWTP.
It helps me out on this one, thank you very much.
Probably related to the fact that the initial STEP was done with a newer tool than my Solidworks 2023...
Have a nice day.

In general, also look at these:
I've heard of a lot of problems if the " Enable 3D interconnect " box is checked.
Indeed, it is very likely that it comes from the "Enable 3D interconnect" box because it is the only setting that differs. I'll test it occasionally and I'll post my answer next to close the topic if it comes from there.
Thank you for your help
Hello Nicko,
I have the same problem as you with SW 2022 sp4. (I didn't touch our settings).
Good luck, @+.

Hello. Being on SW2021, the part is present when opened and I can open it separately without any problem. My opinion in 2 points. 1: For my experience, I prefer the parasolid format to the steps. There is a better stability/reliability I think. 2: your part (PM 3G250: engine apparently) is made up of 20 volume files imported not to mention the surface areas!! It is not a single volume or surface part. As a result, I think that, since in general all the files we import are never perfectly clean, you multiply the risk of problems when opening. I tried to reduce the 20 volumes with Boolean " combine ". Nothing can be done, even by subsets. Your files are not clean. You penalize yourself by importing too many parts. In your place, I would reproduce, roughly, the shape of the engine in a simplified way, with just the essentials in exact: fixing interface, overall size. Of course, it takes time... Your file is not a design file. It is an assembly file of external parts for which you cannot control all the parameters.
Hello @fminisini ,
Your analysis is very relevant but unfortunately as a subcontractor (and I think this is the case for many here), we have little or no control over the type of file received from our customers.
Between the buyer who follows steps with his order without understanding what he is sending and it's normal, to each his own job... And the different design offices that unfortunately swear by step, iges or dxf/dwg, with each of them their share of uncertainties...
In a previous company, I had managed to " educate " one of the big customers who worked with Catia to provide us with Parasolid files and it's true that we save a lot of conversion time, less defects...
I'm probably getting ahead of myself, but in the case of @Nicko it's certainly a customer who did his assembly by retrieving the steps of the accessories on the manufacturers' websites, so I come back to the fact that we don't have control over the quality of the incoming data.
This is a subject on which we could all debate for hours...
Have a good weekend everyone.
Hello
Actually same result ==> test with 3D interconnect enabled the element is displayed (SW23SP5)
Hello
I tested under SW2019, indeed by activating the 3D box it is displayed, on the other hand it forces you to right-click / dissolve the function to be able to isolate and modify the different elements that make up the assembly. (on head assembly only)
Hello.
Unfortunately, I do not have hours to debate on this subject, but thank you for your feedback.
