View Full Version : Spline to Polygon HEEELP!!
McNeely 02-12-2003, 05:37 PM I am having big trouble finding out how I can convert a letter I made
in Illustrator and loaded into Cinema 4D 8 from a Spline Object into a
Polygon object so I can use extrude tools on it... I thought I have done
it bevor, but I just dont get it anymore..... any Idea?????
PS: I do not want to use NURBS because I need a real mesh model for CNC...

using nurbs extrude is the easiest way, and it will give you what you want. set it to a depth of 0, and then make it editable to get the poly plane for you to extrude and manipulate how you want.
otherwise you could try using the structure manager to save the points of the spline and then load them into a poly object, then all you hnave to do is go around by hand connecting the points into one big poly.

Alternative Method:
Drop your spline onto an extrude nurb. Set all movement on the nurb to "0". Make the nurb editable an boom...you have a poly. The downside is that you also get triangles but hey it's quick and dirty.:D

thanks for your quick answers guys.
Ok, what @VestanPance sayd would be the easy way... I think that is how I got it last time... would be great if it worked, but the polys I get are almost unuseable... :-(
I will try the structure-manager way, do not have much reality on how that works but I will find out! :-)
thanks again!

hmmm, maybe i'm not getting it but where's the difference between the first methode mdme_sadie described and vestan's methode? :surprised :shrug:

I think the difference is just that you only get the equivalent of a 2D nurbs cap with Vestan's method.
Of course the hard way is often the best way, and in this case it involves copying the spline points to a poly object and building the damned letters yourself. Not practical if there's a lot of text, of course. Another idea is use the free Elephont program and import as .dxf. An oldie but goodie.

@AdamT is Elephont a Windows app? I am on Mac....
I did a little test with the spline point copying and it works, but I would have to set the point-rate so high, that I almost wind up with the same setup like I would do it with the extrude nurb set to 0.... I even get the same deformations on the edges both ways! Well, now I know why that overlapping of the beavel-corners happens! :-)

there's no difference cosmic. they're identical.

The advantage to building the letters by hand is that you can use hyperNURBS--assuming you make a nice, clean, quad mesh. Then you can also use HN weighting if you're in R8.
I'm on Windows--don't know if there's an Elefont for Mac. Try a search.

I think, this is good place for my problem.
How can I export poly model to work with CNC?
Just curious. But I don't know model and name of CNC right now.
Thanks in advance.

OMG....man I feel like a dope. I have no idea how I missed that first part and simply rewrote what mdme_sadie said. My appologies Cosmic and others.

@freeq - I have the same problem, I will find out soon what kind of data the company needs... we are making letters like the ones on the back of cars...
