Import .ifc file and work on it

How are you all doing?

I need some help... I have an .ifc file that was exported by a program I don't know... I believe it's SketchUp... but anyway...

I need to open it in SolidWorks and work on it...

There's a surface drawn on it that I need to work on in SolidWorks. I open it normally through SolidWorks. At first, when I open it, SolidWorks opens as if it were an assembly. The idea is to transform the "waves" that would be a surface, convert them in some way so that I can work on them in SolidWorks.

Opening the .ifc in solid, it appears like this:

 

 

It's what's in blue that I need to work on...

What I wanted was to break down all the items so I could work with this blue surface in Solidworks..., so the first idea would be to save it as "Solidworks Parts", but something goes wrong..., when I do this, the surface simply disappears, leaving only the horizontal profiles....

the main thing I need is gone...

 

So, I would like to know from you, what I need or should do to work with the .ifc file....

 

The strangest thing is that I have a friend who has version 2017..., I use the latest available, on his, when he opens the .ifc on his and saves it as solidworks parts, all the items are broken down....., and in the latest version, it no longer happens....

 

In his case, when he exports, it looks like this..., with several files:

This is not happening in the current solid, it is a single file without the surface....

I don't know if something has changed since 2017 or if I'm doing something wrong..., I'll leave the file in case someone can help me...🤗
