Thanks for the your in depth response!
I guess on the plugin issue, I’ll probably do my usual; dump all of them in 2016 & update the ones that don’t work. Probably not the best way to do it, but it’s saved me some time in the past.
It does seem like getting Sketchup to use multiple processors is pretty complicated, & i appreciate you describing what you can about that issue.
I guess my main concern, & has been for years, is the overall speed & the amount of geometry that Sketchup can handle. It has improved since v.5, but not exponentially. Having said that, the great number of plugins available, esp. from individual developers, makes Sketchup a much more powerful program than it is in stock form.
It would be cool if future upgrades of Pro took into account a crucial element of working with Sketchup professionally: deadlines! The work-arounds you currently have to do to get Sketchup to run faster, esp. on larger models are o.k., but time consuming.
I think it would be great if Sketchup could get into the speed range that would be comparable to, let’s say 3D Studio Max, etc.
