.step file won't open

[Anonymous]

I have uploaded the .step file twice. I cannot delete the file. Also it shows error while I try open it in Fusion 360. I am use an educational license. How do I solve it?

Zip and Attach the file so that it can be diagnosed.

I have zipped the file in .rar format.

I don’t own rar extractor- only zip.

I've tried opening it in SolidWorks 2020 and received the following error so it looks like the STEP file is corrupt in some way.

I think it worked here:

Yes, you're right - I've opened it in F360 just fine. Interesting that SolidWorks didn't like it for some reason.

Open the STEP file in Notepad.

Is it Application Protocol 242?

I had already opened it in Notepad++ just to check it was readable and to see whether there was anything obviously amiss but it looked ok from a quick glance through. The schema of this file is AP214 so it's a format that SolidWorks 2020 shouldn't have any issues with. eDrawings opens it without any problem.

'STEP File Analyzer' reports:

"*** Syntax Error: For density, the length unit exponent should be -3"

So maybe that's what's tripping SolidWorks up.

Anyway, F360 opens it just fine for me.

It worked fine when I reopened Fusion 360 later. I guess it took time to load in spite of the size of the file even though other files took lesser time to load. Sometimes it takes Fusion 360 a lot of time to load, I am not sure whether it's my  internet problem.

Thanks a lot for the responses. It works fine right now.

I am a student. I am keen on learning how do you know the required formats by observing the codes in the notepad?

It would be helpful if you suggest me some guidelines.

It worked well with Fusion 360 forma. I didn't have any issues while opening it. Thanks.
