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.

Hi Stefano, currently I'm trying to wrap up v4 and not add in any new features but that one might be easy enough to put in, I'll take a look.

Right now you can get the centered result you want by using the Transform > Align command after creating the text.

Hi Michael, thanks for the response and recognising the suggestion! - Stefano

MoI v4 Beta September 10,2020

Adding a new style and changing color. Select 'Pick Screen Color' then move the mouse around the dialog box and the dialog box jumps horizontal back and forth as the numbers update.

Has this event been reported yet?

My screen capture software limited in colors...

Wayne

Hi Wayne, thanks for reporting that, this is the first report of that problem. That dialog is implemented by the Qt framework so that's a Qt bug, I'll see if they have a fix for it that I could apply.

There is a setting in moi.ini which if set will make MoI use the Windows system color picker same as MoI v3 did instead of the Qt one. It does not have a pick screen color option at all though. But if you want to try it, that is set in moi.ini under:

[Color Dialog]
UseV3ColorDialog=y

Thanks,
- Michael

Hi Wayne, I found a Qt open bug on that:
https://bugreports.qt.io/browse/QTBUG-43506

But it's still open and hasn't been fixed.

I'll take a look at fixing it up myself. Having the mouse coordinates is not really useful so if I just remove that text from being displayed that should fix it.

Thanks, - Michael

Dear Michael,

I recognized a strange thing where I am not sure what software is causing the issue.

When exporting in V4 beta Sep-10-2020 a closed curve that was joined from 2 or more single curves in IGES format and importing it to my CAM software, the CAM is importing the curve twice. So I get two times the same object. I tried the same with MoI3D v3 and here just one object is visible after importing to the CAM. Could there be a loop counter issue (the classical n instead of n-1 counter-end issue) in v4? Or is it an IGES format issue between CAD and CAM?

This does not happen with curves that just have one element like a line or a circle, whereas a rectangle is causing the issue as well.

Best regards

Joerg
