Hi Nick,

> Michael - Is MoI large address aware?

Yup MoI.exe is already marked as large address aware.

That means that on a 64-bit system, the operating system will allow MoI to use the upper half of the 32-bit address range for its own use rather than having it reserved for the operating system's use.

So when you're running MoI on a 64-bit operating system, it is able to use something like 2GB more RAM than if you're running on a 32-bit operating system.


> Is it possible to turn this on?

It is turned on already, so you don't need to do anything special to activate this, other than just having a 64-bit operating system.

Unfortunately there is no option for 64bit windows here. Will see that I get used to work on separate files if this goes on. (64bit windows is foreseen for the next company laptop. Order is given, but no clue when in ht next months this will be there so it will for sure take some more time to work in 32bit...)

My main concern at the moment: I don't want to switch to some new (to me) cad system to be able to design the things I need to do now. So to have a 64bit moi would help. For a while the work via separate files will have to make do.

Hi macray,

> For a while the work via separate files will have to make do.

Don't forget the display density adjustment too - that actually makes a pretty big difference to reduce RAM usage on heavier models.

Go to Options > View > Meshing parameters (the settings at the top), and set Mesh angle = 25 degrees, and uncheck "Add detail to inflections".

The display will look a bit more jaggedy but memory use will go down by a chunk.

As this is mainly about piping-this should be helpful. Thanks for pointing at it again.

Hi macray - yeah piping tends to make a particularly heavy display mesh so you'll probably see a pretty good memory reduction with the rougher display settings.

Another thing that I'd like to try in the future is something more like make an initial rough display mesh for everything and then go through and in the background calculate denser and smoother ones but only if there is plenty of memory still available.

Awesome. Thanks.
