I am currently running it on my other machine yes and i found it did improve it but again with the complete model its soo slow. The only way i get around it is by turning the majority of the layers off but obviously there are some points where i need to view the model with everything turned on

Hi Tommy great idea by the way, i've ben scanning through and had a look at the database as im looking to get a new computer at work as i'm cutrrently running sketchup on 2 computers here, one is on vista and the other is xp and both are becoming very sluggish. The reason is the models i'm creating are huge, ranging from 40 to 70 mb each once all the components are pieced together. The models are of new housing sites and the individual houses etc created on their own run perfectly, with only the odd glich when autosaving sometimes. As soon as i piece everything together onto a contoured layout it all slows up, causing problems.

Just wondered if there are any machines that stand out when using very large models as you can't tell on the database what sort of work people are using them for, and the machines im currently using work excellent with smaller models.

I have been trying to drape a layout onto the terrain i have created and every time I do so sketchup stops responding and then eventually crashes. I started trying to drape the whole layout and once i realised it wasn't working i then did less and less until it won't even drape a single line. It goes to 40% then crashes and looking at other peoples post on similar topics they have the same problem.

I've had similar problems on other models i have created and yet some work perfectly fine or partially work then half way through crash. I've tried looking to see if others have had similar problems but they always differ slightly.

If anyone knows how I could over come the problem it would be much appreciated as its causing hours of frustration.
