Who said SketchUp doesn't need to be 64 bit?
-
Can someone please explain to me how is it that with all the improvements in 2014 SketchUp still struggles just navigating through a large model while a third party plugin like LightUp has no difficulty at all to do a high res fly through and running a screen capture software at the same time.
64 bit or not , It seems to me that even the latest SU release is still not able to take a full advantage of currently available hardware.
See the Templar Town Tour topic for a good example.
edit: forgot to include the link.

in SU you can edit the model... sothat the inference engine and automatic snapping etc. is required to permanently interact with the whole geometry, just displaying rendered raster data is a completely different thing and thus can be distributed to multiple kernels or computed by the GPU.

Given the size, complexity, organization and nature of the SketchUp application code, I personally estimate it would take on the order of two to three man years to reliably port it to 64-bit and achieve an equivalent level of reliability from the end product.
That was something I was afraid of.

I wonder if the situation might be leveraged for the generation of an Ultimate SketchUp Pro 64-bit version (with all the bells and whistles sought by power users) via a Kickstarter-like venture?
It is clear that SU is so intricate inside, with old game engine being used etc. that bringing it to 64bit means rewriting it. Patching it may not be the best option.
It is time for our community to build something on Kickstarter basis. There was a thread on it already started.

By the way... I have recently received a 250MB SKP file from an user who couldn't render it. I was surprised to learn that I couldn't even open that file in Vista 32bit. I thought it was corrupted. So I have downloaded it once again. No luck. I was only able to view it in Win7 64bit. An attempt to render the whole model was obviously not even considered by me.

When you say you couldn't even open it, what happens? Do you get a BugSplat? If so, did you submit it?

No good news Thomas. When I open the file SU loads it and quickly reaches ~1.8GB+ memory usage which combined with a space occupied by the system fills up whole memory. Windows message comes up then saying that SU stopped working. BugSplat didn't even have a chance to catch the exception.
Going 64bit is a must, no matter how long it will take you. There is no excuse.
Just a side-note. It is not a model of an airport, large terrain, hospital. It is just a house with all furniture and appliances inside.

Can you email or PM me that model for debugging please?

Was this on the same machine? Vista 32bit crashed with memory usage at around 1.8GB but Windows 64bit - same machine - worked?
How much system RAM does the machine has?
1.8GB sounded much just by loading a SketchUp model. Does that happen with extensions disabled? -

No. It is a model of one of our customers.

Vista 32 (4GB installed, 3.0GB available)
Machine #2
Win7 64 12GBI guess the scenario was following: the model created on 64 bit machine, right at the memory limit. It simply crashes on 32bit system due to lack of additional few hundreds of MB.
I have done it especially for you - yes, it happens with no single plugin installed. I have even taken a screenshot with a cursor showing the position when SU silently crashed.

On a second run for the obvious crash due to lack of memory I have received this:
I have answered Yes... although I wasn't 100% sure whether it was asking "Do you want to format
drive?" 
.Edit: Whole model loaded into SU in Win7 64 requires 2.1GB for SU process.
It won't fit into 3.0GB with a system no matter what.But you can easiy imagine that rendering it inside SU is not an option, when the model itself occupies quite a lot.

Yea, sounds like a tough model. Though not that 64bit SU would help for that machine when it's 32bit OS and have only 3GB RAM.
I still find it surprising for a model to consume so much memory. I'd like to investigate what causes it.@tomasz said:

You mean having the render process inside the SketchUp.exe process? That's not something we would recommend any way.

I fully understand that you, Tomasz, can't send the model to Thomas, but wouldn't you be able to ask the "customer"...??
You could point him/her to this thread and then the conversation could continue between the "customer" and "Trimble" directly... -

No worries. I am already in contact with Thomas.
