hi, i know fusion 360 is not for house design but i try it. It is good enough but now file size is more than 100mb and it is really late to open. Can somehow to reduce file size?

Hello, @alfadex50.

Are the parts of the house mesh files from externel sources?

I had problems opening you design too.

brep bodies that are converted from mesh bodies are huge. and you have a ton of them. not generally recommended to work with fusion in this way (b/c fusion doesn't handel it well). plus most of those imported items have a lot more detail than would be necessary.

breaking the links will help performance. as will deleting the mesh bodies and converting the solids to DM features. right now you have them scaled 3 times, which also adds to the size.

even better would be to create simple models of each thing in fusion . then use joints to arrange in your model.

FYI-it's not necessary to add a new scale command when you want to change the size, just edit the existing one.

great! i did all and it is mosignificant quicker now, especially when i delete mesh files. i am trying also to convert dm feature from parametric because also indeed i didn't need history, but maybe it is late now because i have done too much work on parametric and it cannot manage it.

you'll notice that your converted bodies have a bunch of facets on them. that's a result of having originated as a mesh file. if you go to grab cad, or other model sharing sites, you can find files that are in .step (or .stp) format. these will behave much better for you.

I wouldn't delete the history of your entire model, just of the objects your bringing in. here's a screen cast of what I mean.

Also, you'll want to clean up those yellow errors now. continuing on without fixing is asking for trouble.
