Rhino is running so slowly now and even small files are struggling to open quickly, can anyone offer any tips to speed things up? I even have files that don’t open any more. e.g. deleted out some materials on a 26MB file took 5 mins… I’m pulling my hair out. Is there a cache needs emptying? I’m not running any other programs. Thank you

Hi Alasdair -
Are your files saved locally on your machine or are they on a server or in some synchronized folder?
-wim
Hi Wim, They are saved locally.
Alasdairjmckay, Is this happening in a new file? or just an existing project?
That is the workaround I’m using now. I’m working on an individual building in it’s own separate file and then importing it to another file showing the buildings in that block. It appears to be working okay then but I’ve had this for months now, I’m guessing it’s something in the model…? If so what would be the likely culprits?
If this is model specific can you zip and send us the file to look at, please mention this thread in the upload comments. Thanks
Ah, unfortunately not… NDA’s, sorry. Are there any things I can look at?
Can you provide more detail on what you’ve got going here?
Apologies, what kind of detail… file size 371MB, Mesh building imports so mostly simple geometry apart from mouldings, simple materials though I have ended up with a lot of duplicates. I am dealing with imports from colleagues in sketchup, could that indicate something?
Yes, that raises a few red flags.
Can you run SelBadObjects?
How many individual objects? lots of objects (especially far from origin) can be problematic when the view generates, even if inside a block.
Nothings too far from origin… what is too far from origin? Origin is at centre of model, furthest point away, 350ft
Bad objects are 1 surface and 125 meshes. Is that a lot? I’m assuming I delete and see how it handles as we then know that is the problem?
350ft, not a problem, miles away…
Yes, delete or rebuild the bad objects.
Thank you, will give that a go once I have a minute
Hi, My Rhino started lagging with every small selection. I’m not sure what to do about it.
