how do you lock in solids

#1

Hey guys thankyou for the help in advance. I am building a robotic arm for a class at school and my teachers wants me to make a 3d model. I already had rhino 3 on my computer so I have started to play around on it and I have a few questions.

  1. How do you turn a 2d outline into a solid. I used extrude but it won’t “fill” the object like a solid it will only display it as the outer edge of the object.

  2. How do you join two surfaces like if I made a cylinder and I wanted to attach this to box so that when I moved them they move together.

  3. How would I make the joints on this. When I go to animate it how would distinguish the joints.

Any and all help is greatley appreciated. This is only my second day on the program and I have done the three tutorials packaged with rhino along with a tutorial to make a cowboy hat but none of these answered my questions. Thankyou Joe

You know you could find that info from Rhino help <F1> but Here I’ll tell you anyway…

  1. Make sure curve (2d Outline) you created is closed… and when you start to extrude…from command make sure you chose Yes to have it capped.

  2. To join one surface to another, just click on Boolean Union tool. (it should be on left panel of the software ONLY if tool is in default)

  3. To animate you’ll need Bongo Plugin… If you have one, I wouldn’t know how, I don’t have that plugins or yet never tried one myself.

Thankyou guys so much for the help. I have been playing all this afternoon and have learned so much rhino is quite amazing. I have stumbled across another problem though. I have a square hole cut in a solid. I want to put a box with a greater depth into that hole but I need a way to mate the two surfaces. maybe there is something where it automaticallys mates the surface or something of that nature.

Thankyou

ok well I have gotten past my last problem and a new one has arised. When I go into flamingo and choose all my materials I can see everything in my “perspective box”. Like it will render fine in the perspective box but if I try to hit Raytrace>Render then my cpu usage goes up %100 and the program locks up. I even left it all night because in task manager it said that the program was still running and this morning i had to use ctrl alt delete to close the program and thankfully rhino automatically saved a recovery file for me to use this morning but I still cant get this thing to render. Please help

PS i just checked it again an it wont even open the rendering window and show whatever percentage. It stays in the normal rhino scene and in the command line it says creating rendering meshes.

Thankyou

what kind of system do you have? Memory? Video Card? Hard drives? Are you rendering best quality or normal or just a liitle qt? What else are you running with Rhino?

I have a toshiba satellite With a intel centrino at 1.86GHZ with 1gb of ram and 100 gb hard drive. I am running nothing else on this computer while I am using rhino except for the two plugins flamingo and treefrog. And I have it set on the medium qt

ok I fixed it I had one bad object and one little pice left over from something that was waaayyy out in the middle of nowhere.

Thankyou for the help and anybody have some tips on rendering.

Use the zoom extents and it will show you… Your computer may slow you on big things… But it sould be fine as long as you keep it all cleaned up… the video card is important, 256 or better to run ok, for best run 2 512s w/agia of 128 or 256…

Good luck…

Something just popped into my head as I was reading this thread. So there are many ways to save render times but really all of them effect the quality of the final render (things like mesh qulaity/res/reflections/ect) except you have to remember that any geometry in the scene Rhino will render even if its not in the frame. So If you ahve a rather complex scene and your renders are taking a while make sure to hide everything not in the frame.
