HI Michael,

I just found one issue which bothers me a bit,
when you export to 3DS the uv's created are a mess, in OBJ it is fine,
I attached a picture for you,

Best regards,

Thor

Hi Michael,

I'm having a look at PDF import and it doesn't appear work at all. I have been trying out a lot of file but none of them seems to be loaded although they are processed fine in Rhino. Could you post any PDF file that works?

Hi Michael:

As soon as I saw the new features, I though to take the hull up. :-)
I´ll tell you about that...thx

to tyglik: Yesterday night I made a probe. The "normal" pdf (like a document) doesn´t work, obviously. :-). After that I tried with an AutoCAD drawing converted to a PDF and it worked.

I send you the file:

Bye!

What is exactly the format PDF who is not the normal "document" format?

Hi Pilou:

I wanted to say with a "normal" document, the text document write in MSWord or any word processor.
The thing is that I have been trying to import pdf, and the most of my pdf are text documents and they weren´t work.
Now I have been using the WordArt and drawings tools of MSWords and they works, but it isn´t very interesting, actually :-)

Bye!

Hi Thor, if you have welding turned on MoI does not write UVs to the .3ds file at all...

That's because .3ds does not have a proper way for 2 faces to share the same 3d point, but have different UV coordinates. .3ds has a limitation that it can only specify one single UV coordinate for each 3d point.

If you turn off welding, then UVs will be written because points are not combined into a single point along common edges.

OBJ doesn't have this limitation. In its structure, it has a way to have polygons share one single 3d point, but have different UV coordinates for each polygon.

.3ds is limited in other ways too, like it has a limitation of only having a maximum of 65535 points for a single mesh. If your program supports OBJ, I would recommend focusing on using that since it doesn't have these limitations. Only try to use .3ds if you don't have any other option.

Hmmm... Actually, I have also tried MSWord's drawing tools, but it failed as well... It looks like the pdf driver could cause the trouble. I use Adobe Acrobat 5.0 Standard Edition. -Petr

Hi Petr, can you please send me a couple of the PDFs that don't work? (David posted one that does work)

I had tested this with .ai files saved from Illustrator CS that were set as "PDF compatible". I assumed that PDFs would also follow this same structure, maybe something is slightly different.

PDF is a pretty difficult format to support well, it's structure is pretty complex. It will probably take some tuning for it to work better.

Hello:

This is a file created with MSWord and converted with ALLPDF (you can try to convert online here https://www.pdfonline.com/convert_pdf.asp)
Bye!

Hi Petr, I tried some more PDFs over here and I fixed up some bugs. I think it should be working a lot better now.

I put up a patch here: http://moi3d.com/beta/pdf_ai_patch.zip . If you download that, it contains a new moi_lib.dll file, just copy it over top of the one from the last beta and PDF import should be working better for you. Please let me know when you get a chance to try it next week. Thanks!
