Thank you so much for your time replying and explaining.
I will make sure to re import taking care of the settings you describe
When I look at my numbers
Awwww, how to go back and check all the groups etc it all? It seems very daunting.
Since my last message I managed to try my file in my HTC VIVE helmet and
was blown away actually to be able to walk around (on floors and stairs) that showed nicely
All my, imported wall and floor Art showed perfectly well.
I re-saved my SketchUP model in “cm” and re-exported as FBX
and now it showed perfect in size to the “humans” in Twinmotion

Twinmotion won’t recognize and will apply the material to the entire element

This might be one of my many issues.
I have a lot of glass. Unfortunately SKU has very few standard glass to use.
The new TM23 has a wide array to chose from.
BUT how to set these glass in SKU I have nearly used all basic materials available.
I am very concerned to change glass into random types of materials that I still need to import or create.
I thought of making my own patterns like wallpaper that repeat "material glass A, B, C , D etc)
I know somehow glass seemed to , like escape" into the back faces of planes
and rush around the model and often made me redo again and again.
I also don’t know maybe the “reverse faces” is an issue. But how to see if
a plane that has been loaded with materials and textures is, reversed or not?
Dumb question you may think for someone using SKU since the free Google
I often filled floors with just a line across from point to point and then when the plane
filled this part of the floors (I have many odd shaped floor areas) then I delete the line across.
I still now have issued with “intersect faces with model”
then the part to cut if off from is too large it just wont do it
sometimes SKU also splash/crashes in when I attempt to do that process
At times I seem to have really a hart time doing the simplest of things
like cutting away something out of the floor.
Then I go to make a circle or squares
and delete the centre and then start nibbling away
what I don’t want to see
I posted a several questions on the TM forum about all my issues.
I have posted several issues here when I started to try to build in Unreal Engine
(very cumbersome)
I was wondering maybe I should try to extract in SKU only the building
and then import one by one all the groups?
Again I see months of work only for that as I have to start.
TM again and again. The making of my FBX takes about 15 minutes each time
after any change in SKU.
I am VERY concerned about uploading my entire model into their cloud etc.
It’s eight months of work anyone interested could just take it and run and make it his/her own
there is no protection against that. Or I don’t know how to build it in …(Yes all the Art is originally mine) that I can prove.
But again I don’t have the resources to find or sue hackers or thieves with the law.
That is I guess why all is so secretive here in Vancouver with the game studios.
I was on a tour in one of the world big studios called ATOMIC , no cellphone were allowed
no seeing any of the hundreds of screens close up etc. They promised that they had plenty of all types of jobs for people over 55+ with CAD expertise.
After I showed my work on tablet to the HR CEO guiding us at a later stage he gave me his linkedIN contact and invited me to apply directly to him, no need to send resume etc.
He NEVER replied and never said one word 
I had Twinmotion customer service (that is really good and very fast) telling me in an email that Datasmith does NOT work with SketchUP 19. Only starting from 20.
I only get One logo that shows an arrow. I know now how to open the Datasmith file but
I can’t seem to establish an live link.
Although I have 32GB of ram and a medium to good Nvidia Graphic card. 1080
Thank you for your time and consiration
Muchas Gracias
