'Using Rhinoceros' Discussion Thread

[Golden Bear]

Yes, the .wmf works for me but the .ai does not. I cannot understand quite the settings required to get the size to transfer correctly. I'm going to draw a reference bar in Rhino of known rectilinear dimensions so I can rescale in PSP. This just seems cheese-like to me.

Yes, it is my only real complaint with Rhino. I have a standard rectangle 254 x 190.5 which as millimeters is 10x7 inches to represent the bounds of a page. everything must be within the box. select this single view, the click the "Zoom extents" button. "Save AS..." and select WMF. Now the trial end error part. You will get the dialog box asking for image size and resolution to save the image. I have not been able to figure out how to calculate the correct values, but with some trials I can eventually get the rectangle to import into PSP as 3000 x 2250 pixels (10x7" at 300 dpi).

I rotate pieces with Ortho on to get the View I need if the main Bitmap is in a Viewport other than were I need it. I usually have the Bitmap in the Top View, then Copy the piece I wish to play with, then Rotate it with Ortho on if I am going to use it to Cut or Trim another surface. I am not that good with Rhino (or anything else for that matter) so if them seems dumb, please ignore.

Now you see why I stick to vector data!! My simple brain can handle millimeters only, so if I make a line 12 mm long, and make sure the ai file is in millimeters, and that 1 mm in the model is represented by 1 mm in the ai file (it doesn't have to, so you can build things in 'real' dimensions, and then output the ai file to scale; actually very useful!), then importing the ai file into coreldraw gives me a line that is still 12 mm long. Pixel images (bitmaps) are essentially dimensionless, so if you have a size requirement both the printing scale and the pixel size of the image are important. And someone else is going to have to pick up the baton at this point!

This doesn't help at all, does it??!! Sorry. Are you using version 3 or 4? I just looked at the v4 export dialogue, and it looks to have very comprehensive controls over how the final image is exported. However the image produced seems to be anti-aliased badly, so I will look into this further.

Anti-aliasing is not that bad a problem as long as the resolution is high enough. I think Photoshop would handle small differences in colour quite well... (PS I'm not a bitmap person and I know this might be nonsense)

Well, I'm using PSP so the .ai doesn't work. I drew a box 1" long by .5" high on the same plane with the flat parts. Then I did the .wmf and picked 1:1 which made the thing hugish. I made the paper size huge too and sent it off. It showed up but a little out of scale. I measured the box and did the math to resize the image. It seems OK. It still seems cheesey to me. Rhino (4) should be able to export directly to something 2D - tif, gif, jpg, PSP, anything of some sophistication better than .wmf. .ai would be nice if it worked.

Actually, WMF is a reasonably sophisticated vector format. Its just that Rhino doesn't use it fully; it only outputs "LineTo" style vectors for everything so arcs turn into a million tiny vectors rather than using the "Arc" vector. I also find it frustrating that it doesn't use "rectangle" or "circle" either for those shapes.

Um, sorry for Reviving this thread, but, HOW does this software work?! Can I download it for free?! I need help with at least 4 designs! Thanks..........

[Lex]

Um... Rhino is actually a quite powerful industrial CAD tool, the free version only allows you to save 25 times. And the full version is quite a price of >$900. I think there's a student price of $200 approx so that might be affordable... But if you become proficient at it, it becomes much more useful than the Meta/Pepakura combination. Basically, if you are new to 3D design then try playing with the free version before you buy.

Where exactly can I find the Rhino 'articles' as described?
Thanks heaps if you can point the way.

Hello, guys!


I´m new here
So, completly lost within the forum´s interface...

Please, where can I find out the Tim´s tutorials, please? Could somebody kindly help me? I thank in advance.

Congratulations for your nice tutorial, Tim! I read one chapter in a PDF file, and it helped me a lot to initiate on Rhino secrets (well, I am a Rhino newbie too! More yet, a 3D rookie!) But, reading your first step I got a jump to 3D world. So, I would like very much to follow the next chapters of your SU tutorial. Where can I find it, please?

To everybody: forgive my fenglish - I am also new on your language!

Hello from Brasil and best regards to all!
