Additional system information

MSI MEG Z890 ACE Socket 1851 mobo;
Intel Core Ultra 9 24 Core LGA 1851 285K 5.70GHz cpu;
256GB Crucial DDR5 RAM; Crucial T705 4TB NVMe PCIe 5.0 ssd + 2@ 4TB Samsung 990 Pro PCIe 4.0’s for overflow;

How to reproduce

(refer initiating / discovery report here

Start Orca as Admin, with Lasso running to keep it on performance cores and high priority.
New project, save it, import 1.4Gb .STP file generated with Solidworks 2026, of a 27m long mining machine we want to make a 3D demo prototype of. This file has been optimised by unticking materials etc and it opens perfectly in Autocad 2022, in about 10 mins. Smaller files (parts of the main file) open and slice fine.
At around 30 hours get popup prompt for scale, select autoscale
Get popup to say application to be closed due to call to unavailable RAM, with this explanation.

Expected results

The file should open, then I can scale it at 1.7% and see if it slices OK!

Here is a pic of the 3D print prep'd model that I am trying to import, mostly elements have been thickened to allow 3D printing - there may be some 'fails' where post-processing is needed. I need to have a crack at it to see what works and what doesn't, but cannot get the thing to load to even find out:

Typically, 'dumb solids' have been extruded over details that can vanish under the now-external surface. Undoubtedly these unneeded details contribute to size of the model, but it is a big deal to get rid of them, although many have been deleted where practical. Just to do the thickening was a solid 10 day exercise, but trying to get it in to slice it has taken longer!

Project file & Debug log uploads

debug_Mon_Feb_02_08_38_59_49496.log.0.zip

The following project file is basically blank as it has never been able to be saved as importing the model crashes the app.

Anything else?

As a final check, I am in the process of running it in a non-elevated condition and will report back to see if any difference to elev condition. Given it has failed many times previously, I am not expecting a different outcome on this (now latest nightly bar one) version.
