Making a paper model with Rhino

#1

Hey all,

This is really one of my first posts on the forum, so hello. I wish I could begin learning from you people under better circumstances, but I am in dire need.

I am taking a class at my university that involves teaching the principles of 3D modeling and how it translates into the real world. That being said we are required to make a model in Rhino - why in the world we are using this program since the rest of the classes teach Maya I have no idea - and then use that model to create a flattened pattern that can be cut and pasted into a paper model.

My problems are immense, mostly because we book we use is actually an out of date tutorial book designed by an old professor. His example uses a long processes of lofting splines into revolved surfaces that can be unwrapped. My professor, however, wants more creative designs, and i really want to try and model an AR-Wing from Star Fox.

Now I feel like the best way to approach this would be to use basic primatives and subdivide and manipulate the verticies and faces as nessecary - my previous 3d experience is in Maya. However, I cannot seem to access vertices using a basic box primitive. Am I missing something so basic?

Also, the plan involves flattening out the 3d objects into printible plans such as these.

Is there any function in Rhino that will flatten a model in a way that provides for easy printing, or do I really have to redo the model in revolved, faceted, surfaces, unroll it, and then manipulate it by hand? If this makes no sense to you, then know it makes little more sense to me.

Thanks in advance!

I am not really understanding what you are trying to achieve. Are you inquring you want to model those in 3d out of flatten image or is it that you want to draw exact like flatten image using rhino 3d and establish surfaces?

I can tell you conceputical or workflow on rhino is way different from polymodeling, maya like you said. If I were you, my approach is to draw a curve based on flatten image, using <Sweep> or <EdgeSrf>, <Trim>/Spilt> prior to what is in between surface then use <ScreenCaptureToFile> save it as .bmp or .jpeg and run in photoshop add some color or such details prior to image.

If I did not answer you correct, my apologies perhaps its something you need to elaborate on what you re trying to achieve.

I am not trying to go from flat to 3d model, but from model to flat paper plans. I think I am going to forgo using primatives and just move straight into using the splines, and loft the pieces from there.

Try looking at Developable surfaces: http://www.rhino3.de/design/modeling/developable/

That might help. :slight_smile:

This thread and the rest of the site should be of help:
