Thread Split: Some posts in this thread have been moved here
From: Michael Gibson
A new v4 beta (version Oct-17-2018) is now available for download here:
http://moi3d.com/beta.htm , also linked to from the download page on the main web site.
The main focus for this beta is a polygon sub-d surface to NURBS conversion method, available on the side pane under SubD > Create > From file. This allows you to open an .obj file that contains a sub-d polygon cage and have it converted to a high quality NURBS object in MoI.
Some other stuff:
Settings for page size are now available in PDF/AI exports.
Fixed crash bug when modifying display mesh angle.
Updated STEP export to fix problem with object names not coming through to SolidWorks, Fusion360 and KeyShot.
Added moi.ini option to set current file name with foreign file types. In moi.ini under [Settings] SetNameWhenOpeningAllFileTypes=y When set, the current file name is set for all file opens not just .3dm files. Requested by Alex on the forum here:
http://moi3d.com/forum/index.php?webtag=MOI&msg=9044.41
Updated DXF export to allow the dialog to be suppressed and options set by script. Parameters that can be set are:
// DXF export function parameter options:
//
// NoUI=true
// ExportType=2d | 3d
// ProjectionView=top | 3d | front | right
// WriteCurvesAs=splines | cubicsplines | polylines
// PolylineAngleDegrees=10.0
// UseSimpleEntities=true
// NumDecimalPlaces=12
//
// GenerateHiddenLines=false
// HiddenLineLayerMode=fromstyle | custom
// HiddenLineLayerName=Hidden lines (layer name to use when layer mode = custom)
// IgnoreTangentEdges=false
// Resolution=25.0
Thanks, - Michael

Ok Michael! Got it :)
Downloaded and tested on the fly the new "SubD" feature!
The first try is ok!
Thanks a lot!!!
It's a very promising feature!!
Just in order to understand this new tool, what are the differences from Max's Subd scripts?
From: mkdm
Great thing the chance to have "Settings for page size are now available in PDF/AI exports."
Perfect!!

Hi Marco, re:
> Just in order to understand this new tool, what are the differences from Max's Subd scripts?
The main differences are that it gives higher continuity quality (G2 with a few exceptions like at unusually high valence vertices or at some cases on open boundaries) and larger combined surfaces.
It would be interesting to compare the output with other converters.

Ok. Got it. Thanks for the info :)
Based on some very quick test that I did I see that your new implementation is much faster than Max's script.
And I think that this is normal, because now you're running compiled code without the overhead of the script.
Anyway asap I hope to find some spare time (late at night) to make some detailed test in order to send you a detailed report.
We'll catch up!
From: mkdm
...P.s..
And above all now we don't need to use the "ImportObj" script.
very well!
From: mkdm
...P.S (2) :)
Michael i have a little request.
In order to do some real performance test and comparison between the subDiv of this new beta and the Max's SubDiv version I only need latest version of Max's subDiv that works with Moi V4.
Could you please give a link to that?
And, two requests for the next implementation of the subDiv in the next beta:
1) Very important.
Actually Max's counterpart of subDiv has a GREAT advantage over the builtin Moi's version: it allows to specify the "smoothness degree" when the imported obj it is going to be transformed into nurbs.
Max's plugin expose a slider for that.
It would be really convenient to have this chance also for the builtin Moi's subDiv.
2) The new builtin subDiv does a GREAT job in reducing the amount of patches.
This is wonderful.
But...there are some use cases when I need to maintain the exact match between the flat planes of the imported obj and the resulting nurbs patches.
Now it seems that this is not possible. The builtin subDiv always reduce the number of resulting patches, without any chance for us to decide its behavior.
hank you very much and I stay tuned :)
Ciao.

does this new import/export OBJ replace all the previous ? Your, the _import Obj by Max Smirnov...
French Site and Forum updated! ;)

Simply amazing Michael, thank you so much for this feature !
@mkdm,
Do you realize you get the best sub-d to nurbs technology here ? the surface continuity quality is above anything else on the market :O)
From: mkdm
@ You : "..Do you realize ?..."
ABSOLUTELY YES!!
In fact I was the first to congratulate Michael for this new feature! :) :) :)
And my latest request are only for ask more freedon about the "degree of smoothness" for the next beta, like Max's did in his plugin.
Michael has added a wonderful feature.
Very promising!
For @Pilou:
I think tha actually the _importObj plug in is still NECESSARY, because thanks to it we can translate the imported obj into a flat planes polysurfaces nurbs
Maybe in the next versions of builtin subDiv we will have also the chance to do a "rough" import of the obj, without any subdivision.

Hi Michael,
looks fantastic! However i have problems with my very old iMac and my very
small graphics card, so that i show my result in MoIv3.1
Left Bunny from MoI v4 beta 175 patches and unfortunately no solid.
Right Bunny from PowerPack Pro for ViaCAD Pro v10 185 patches and solid.
Best regards
Stefan
From: amur (STEFAN)
O.k. apologies Michael... The bunny from MoI v4 beta is now a solid too, after i scaled him up.
The original is probably to small for stitching it into a solid.
[EDIT] also after scaling the bunny up the display problems went away when moving the
model! I should from now on work with the v4 beta, to see if i can find glitches etc!
Best regards
Stefan

MoI4 is still processing Stanford bunny...

Hi Brian,
maybe you have a very high-res quad mesh? My bunny has only
2333 quads (and no triangles) and was processed in seconds,
on my old iMac.

I think it's available on Max's file archive page. To find that, go to
http://moi3d.com/resources , then the link for "Max's file archive", then look for Subdiv_beta9.zip .

Sorry but no I don't expect to have that in the new built in function to do this, it's an unusual function that is not typically part of how sub-d smoothing works with polygon modeling programs. You should use Max's plug-in instead if you need this.

It might be possible to add an option for this in the future, it might help if you could describe more about why you need to have a single polygon to single surface match.

Attached MoI file with Modo IntegrityWare SubD Nurbs Rhino export and same file converted with SubD Create.
IntergrityWare has some control over patches by Material Tags but imported file was not a solid until I separate and re-join patches.

I guess it depends on what you're doing, if the new function does what you need then yes.

There seems to be a problem on older iMacs with the new display engine function in v4 that caches display information on the video card.
I've just received an older iMac over here so I can test it and see about fixing that. But for now you can turn off the caching by the setting described here:

Can you please post or e-mail me the original unscaled one if you still have it? That is probably something that I can fix up.

Yes currently he doesn't have any website set up for Faircad3d.
