Thanks Michael,

That works for me, cheers.

< Not bad! That will be from the new parallelized loader in v4, it's able to chew on processing objects using multiple CPU cores> quote from Michael


387 MB .3dm ... 4.43 sec ! Thanks for the hard work !

---

Sorry to ruin your coffee break! ;)

Do I dare ask how long it takes in v3?

- Michael

---

23,43 sec on V3

---

That's not really too bad in V3, not long enough for a coffee break... But it is pretty convenient to have it so much faster.

The other thing that is nice is that it doesn't lock up the main thread while it is loading anymore so you don't get a frozen screen while it is busy crunching on the file.

Hi Michael, is there a file size limit with .3dm ? I tried to stress test MoI here, copying the model 20 times. It gives a 2.39GB .3dm file, however when reloading the file I only have 5 copies ... and an half model.
(NTFS file system, so I don't thing it's an disk format limitation).

V4.0 Loading time was about 40sec ... Memory usage is bellow 18Gb (/64). Moi 3.0 just crash after a while.

It's a very dumb usage scenario ...

Hi PaQ,

re:
> Hi Michael, is there a file size limit with .3dm ?

Not that I'm aware of. But maybe there's some 32-bit limits in it for some data arrays. Can you send me a link to the big file so I can take a look?

Thanks,
- Michael

Hi PaQ, so yes there is a 32-bit limit that you ran into there. The limit is that any one "chunk" of the .3dm file can't be greater than 2GB in size for v4 and earlier 3DM versions and currently MoI writes a Rhino v4 .3dm file by default when creating a brand new file.

Rhino v5 .3dm files instead have 64-bit chunk sizes so they don't have the 2GB limit.

I could set MoI to generate Rhino v5 .3dm files by default instead of Rhino v4 .3dm files, but it's not that great of a thing to be messing with right at the very end of a beta cycle. For now I'll set up a moi.ini flag that will let you set it to write Rhino v5 .3dm format and in the next MoI beta if you set that then you should be able to generate massive files ok.

Hi PaQ, so one odd thing is that if you have any annotation text objects in your model (Dim > Text), it will write out a Rhino v5 .3dm file to make some text properties go into Rhino ok. So one side effect is that should also make your mega version save work ok as well in the current MoI beta.

So if you want to give that a try, go to Dim > Text and place an annotation text object anywhere after you have done the 20 copies, then you should be able to save it ok. I guess you'll have a 9GB or so file size, does that actually work?

- Michael

---

Hi Michael, thanks a lot for taking the time to look at the file. The only goal with this stupid 20 copies was to get a real cofee break when testing the loading time. I will give the dimension trick a try, and tell you how it goes :)

---

So I added a text + horiz line dimension after the 20 copy (it requires a bit a patience :P)), but saved file is still 2.42Gb, "only" 5 models are saved, and the dim annotations are gone when reloading the file (makes sense as it's probably the "last" object in the list).

---

Hi PaQ, dang I thought that would do the trick. Thanks for testing it anyway.

Hi dear Micheal I have a request on layer management system, it's will be useful if we had the possibility to lock a layer when you hide or select, and an other but maybe more complex the ability to menage groups of object maybe with an other windows similar to layer manager for groups.
A simple system for grouping a couple of objects make simpler handling correlated solid during transforms, and that maybe is useful when import a model as a block, grouping like collections inside Blender make more endless possibility on managements of assembly
Thanks!

---

Hi pafurijaz, grouping is something that I do want to work on in the future.

You can lock/unlock items in the Scene Browser currently by using Ctrl+LMB on the left side of the item:

I searched in this layer form filed many times but I not had a success, thanks, Moi has a lot hidden features build in the UI.

---

Hi pafurijaz, it's documented in the Scene browser section of the help file:
http://moi3d.com/3.0/docs/moi_command_reference11.htm#scenebrowser

- Michael

---

I also noticed (accidentally)
F1 = context sensitive help.

---

thanks very kind, I started without documenting or tutorials, is too intuitive to me and is my fault, I also have many PDF.

---

Hi pafurijaz, yes after you've been using MoI for a while that may actually be the best time to go over the help file documentation to find out various smaller details. Those are kind of hard to absorb all at once when you're just starting.

Hi Michael,

Just like to know if this feature exists or if it could be viable in V4 "final".

Text tool centre alignment.

Ability to centrally align as default option.
User would put the text point on origin.
If one letter typed say an "I" its centred on origin.
If 3 letters typed say "moi" the "o" would be the letter
closest to origin.

Nb. If the origin of the text is placed somewhere else asides the "origin"
then the text is still centrally aligned horizontally to where the point was placed.
