How to reduce model size in sketchUp as layout is not responding

Hi,

I’m studying interior design as a home study course. Sketch up is very much self taught with the help of youtube videos. I have built a small studio apartment with Mezzanine as part of my assignment project but i think the file is too heavy. For example, when i go to export my scenes to layout and try to make any form of adjustments to viewport layout becomes unresponsive. Also any new scenes i create are not pulling through, even with relinking the model in layout. I am at a loss as how to resolve, whilst losing days of work.

Any help would be much appreciated.

Many thanks
Natalie

Post your LayOut file and SKP model and someone will be able to have a look.

If it’s too big to drag into the reply window use WeTransfer or Dropbox.

Also update your profile - which SKP version and what operating system - Sonoma, Sequoia, etc.

Hi Mike,

Just send across on WeTansfer to your email. I am using a Student Licence of Sketch up 2024 version. Operating system is Sequoia 15.1.1

Many thanks for your help

SketchUp for schools is an online version for primary school kids.
You would choose Pro…

Ok. I don’t see it yet on mobile. When I get back to the office I’ll have a look.

Sequoia is not fully supported, so there might be some issues there that I won’t be able to diagnose.

There’s no link.

Nothing in email, nothing in Spam.
You could post the link here.

I fixed incorrect tag usage.


You had purged unused components and materials which is good.

There are a few ridiculously large texture images that could stand to be reduced.


Is your model’s “story” about Anti Smell Soap? If not, does the soap even really need to have a texture at all?

I ran CleanUp3 to merge coplanar faces.

There are still some pretty “heavy” objects in the model. Loads of edges and faces. They could stand to be put on a diet, maybe using Skimp.


Although not related to file size you have a load of exposed blue back faces which, if you want to render your model, could cause problems. Those should be corrected.

The cleanup I did reduced your file size by about 25%. If you slim down those obese components or reduce them with lower poly ones you could make a big ger reduction.

That’s Amazing thank you, as i mentioned I’m very new to Sketchup so learning as i go along, mainly through roadblocks along the way. So thank you for taking the time to look and explain. Would it be possible to re-share the reduced file?

I have actually just downloaded the skimp and have used it on a few items, so I will continue to work my way through the model to reduce additional and look into the heavy textures.

With regards to the Exposed blue/black faces that may cause rendering issues, could you explain this further and how to correct?

thanks again :slight_smile:

Many rendering applications will only render the front faces (shown in white with the Monochrome face style) and will skip the back faces even if they have materials applied. To fix them, edit the objects, right click on the blue back face and choose Reverse Faces. You’ll likely have to reapply the materials to the front faces.

When you are creating your own objects you should stay on top of the face orientation as you are modeling. Don’t apply materials until the geometry is correctly done.

For content you get from sources like the 3D Warehouse, don’t import them directly into your project. Instead, import them into a separate SketchUp session so you can check them out, clean them up, reduce them with Skimp, correct bad face orientation and so on. Only copy the object and add it to your project once you are satisfied that it’s going to be an asset, not a liability.

Think of the separate SketchUp session as a furniture store. You go a sit on the couch, measure it, touch the fabric, etc. before you commit to buying it and bringing it home. And if you do bring home a piece of furniture or whatever and decide you don’t like it, remember to purge unused components and materiuals. Simply deleting it from the model space is like shoving the couch up into the attic where you can’t see it. The thing is still there but it’s not adding anything useful to your living room. Pretty soon the attic is full and the ceiling collapses on you.

SketchUp has a campus where you can learn a lot: learn.sketchup.com
And they have a good YouTube channel with several series of videos for beginners as wel as intermediate users…

As to showing the model in LayOut, it seems to be so heavy that I would recommend keeping all your viewports to use Raster rendering.
