RAM and CPU

[mark.brueton]

Using Civil 3D 2019 on a windows 10 laptop with i7 processor and 64 GB of RAM.

Attempting to performing some fairly straight forward Civil 3D tasks and the RAM just seems to max out at about 5GB and plateau (CPU about 10%) after about 30min and then forced to crash out, very frustrating.

Is there anyway to get Civil to use more RAM and CPU?

I would check to see if there is a virus scan running on your drawing files, and if so make dwgs and associated files exceptions to it.

Also, what is the size of the file?

64bit C3D shouldn't have a limit on ram usage.

Having said that, if your drawing has to juggle 5gb+ you might want to clean things up with data shortcuts and maybe clip/optimize your rasters.

If it's not point clouds or rasters inflating your drawing's memory usage it's probably a memory leak that eventually causes a crash. Usual drawing cleanup/repair measures would be used for that.

Low CPU usage is generally expected because you probably have a 6-8+ core processor and C3D mostly does single threads operations. C3D can use multiple cores on a handful of operations with WHIPTHREAD set to 1 but the program really wasn't designed for coordinating multi-thread operations and you will experience draw order and stability issues which goes counter to what you're trying to achieve.

No magic setting I'm afraid. Clean house and hope for the best.

2019C3D is not new: so what is these days on that laptop? Or is it the laptop that is the new?
