Hi,

Can I export the curves drown in MOI ?

because I can export Solids or planar but I loose my curves.

Thank you

for only 3D curves
SKP format for Sketchup works fine

Else format AI for planar curve

but surely more formats can work

Maybe a board with all combinings will be a good thing !

ok merci frenchy

But I need to export my Curves in Bryce 3d so in .obj format or .3ds

Thanks

Maybe export as a volume + curves and kill surface inside prog?

It seems you can display volume and curves in the export dial box but not export the curves.

Hi Alexito, MoI v1 can export curves to 3DM, IGES, and AI formats (2D only for AI).

For MoI v2 also adds curve export to STEP, SAT, and SKP format exports.


> But I need to export my Curves in Bryce 3d so in .obj format or .3ds

Even though it is technically possible to store true curves in an .obj file, it is very rarely supported. The vast majority of programs only expect to see polygon mesh data in an .obj file, so MoI does not try to export other kinds of objects into it, only meshes.

For 3DS, I don't think it is even possible to store a curve in that format at all, I think it is only structured to hold triangle mesh data.

Do you have any example files that have curves in them that you can load into Bryce?

If so if you could post an example, that would let me see what it supports for transferring curves.

But most normally 3D curve data would be transferred with 3DM, IGES, STEP, or SAT formats to other programs.

But Moi don't export it ;)

That's cool, but I think Alexito was asking about loading curves into Bryce and not Blender?

Does Bryce support importing curves in obj format?

No Michael Bryce doesn't support importing curves in obj format .

But you said that MoI can export curves to 3DM and Bryce can Import 3DMF

is it the same thing or is far from it ?

Bryce can Import a lot of formats I will give you the list maybe we will find something.. ;)

Thank you Michael and Pilou

here it is :


Bryce can import objects saved to the following file formats.



TrueSpace (.cob) Versions up to 4.0 are supported. Material properties are supported.

VideoScape (.vsa) All versions are fully supported.

VRML1 (.wrl) Imports all properties relevant to Bryce, including camera, light, and surface and material textures.

LightWave (.lwo or .lws) Both objects and scenes are supported. The camera, lights, and all objects (with material information) are imported. Versions 6 and up are not supported.

Heightfield (.hf) Used to import descriptions of heightfields (terrains).

USGS DEM (.dem) All forms of DEM files are supported.

USGS SDTS (.ddf) This format is the new USGS format which will replace DEM files.

Portable Greyscale Map (.pgm) Used to import descriptions of heightfields (terrains).

3d Studio® Objects (.3ds)

3DMF (.3mf)

AutoCad® (.dfx)

Direct 3D (.x)

Wavefront (.obj)

WCS Elev (.elev)

WorldToolKit® (.nff)

I had yet seen the Bryce formats but seems there are no possibilities!

Bryce does not work with curves. Notice no curve tools. if the curves you want can be planar, then you can trick it by extruding your curves in Moi, selecting not to cap, then export the obj. Then in Bryce, give it a Y attribute of 0.

Curve.

Hi Alexito,

Nope, those are totally different.

3DM is the Rhino file format.

3DMF is the file format from the old Apple Macintosh Quick Draw 3D system (Wikipedia link), which was abandoned by Apple about 10 years ago so it is a very rarely used format in general.

Hi Alexito, nearly all of those formats that you list there do not any capability provided within the format to hold curves.

Those are mostly set up to only contain polygon mesh objects.

One exception in your list there is DXF - however DXF can contain a lot of various types of objects including polygon mesh objects as well as things like lines, curves, circles, arcs, .... But it is not unusual for programs that are designed to only work with polygon mesh data to skip all these other kinds of things and only read polygon mesh objects that can be found in a DXF file, most likely Bryce is set up like that.

If you'd like to try, I do have a DXF converter that you can download from here:
http://moi3d.com/wiki/Resources#3dmCurves2DXF_converter

That is a small stand-alone converter program that can take a 3DM file saved from MoI with curves in it, and then generate a DXF file with curves in it.

You might give that a try, but my guess is that Bryce will not read the entire DXF file and will just skip the curves that are in it. But it is probably worth trying out.


Basically if a program is not designed to work on curves, then it is pretty hard to import curves into it, that's pretty much what you are dealing with I think.

- Michael

What is the interest to use Bryce for modeling?
It's very difficult !

Nice Trick BurrMan but for what I want it will be too difficult to do.

Yeah you right Michael Bryce skip the curves and even skip the surfaces, in fact Nothing appears in Bryce with my 3dm
file converted in DFX; Burrman is right I think It's simply because there is no curves in Bryce.

I'm not interseted to modeling in Bryce but I want a render with my planes and my curves.

I post you an exemple, it will be more clear

hum hum that crash the programm!
email crash is send to michael :)

Don't change your file before Michael look at!

PS Next time compress the file for the size and time of transfert ;)

I didnt look at the crashing 3dm file but the picture you posted looks like all planar surfaces which will export out as obj into bryce. The curves no, but you cant render a curve anyway.
