Introduction to Maya - Modeling Fundamentals Vol 1
This course will look at the fundamentals of modeling in Maya with an emphasis on creating good topology. We'll look at what makes a good model in Maya and why objects are modeled in the way they are.

Suggestions on how to make this hinge

Hi All,

I'm working on modelling a robot and I'm stuck on how to model the arm hinge (elbow joint). I want the arm to be cylindrical and then merge with another cylinder to make the top of the hinge, then I'll duplicate this for the other side. My problem is I can't get the two joined together satisfactorily because the joint cylinder is larger than the arm cylinder. Any suggestions on how to model this would be greatly appreciated.

Did this very quickly but I think it will give you ideas on how to do it.
Saved the file as a *.MA so should be no probs opening it up - but in case Maya 2014.

Tweeties is pretty good, like an auto spraypainting robot. It does really depend on what kind of robot you want. There are industrial ones, medical, servitude etc, the list is as diverse and endless as we are as humans. I have done one over a can of Rum, mine is based on personal experience as an operator of heavy earth moving equipment. Excavators in particular are a damn good base for robots as they are well and truly equipped to handle a lot of things, hydraulic rams etc etc both hidden and visible. Heavy earth moving equipment is one of the best references for a lot of robots, sci-fi etc...because it is real and works. Mining companies come up with some amazing vehicles....

Anyway Sasquatch my old China plate...here is my very simple geo...to add to tweeties...bombard you with info LOL

cheers bullet

Hi Guys,

Thanks heaps for taking the time to give me some examples, unfortunately I'm having some issues opening the files properly because I'm using Maya 2012 and it tells me the file types 2013 and 2014 are invalid.

I've managed to open Bullet's by turning on ignore version under the open options but Tweety your 2014 file is proving more difficult even though it's an MA file. The script editor fills up with a whole heap of errors including things like can't perform polySplitRing 51 on selection etc. and my scene looks like this.

Rather than mess around trying to find a solution (unless you already know one) could you post a pic of where the 'arm' piece joins on to the plate?

Okay here's the finished hinge, thanks to Tweety and Bullet for their input, and also the finished robot. The design was taken off a picture I found on the web.

Rigging Issue

Okay, so I'm having a shot at rigging my robot character and I've found something kinda strange. I went into component mode and turned on the local rotation axis for my joints so that I could tweak them. Then I went and made some other changes to the skeleton adding in an extra joint and parenting the shoulders to it instead. Now when I go back to edit the new joint in component mode there are three joint orient 'things' sitting in the middle of the model? When I select one it lightly highlights some objects in the outliner so I went drilling down there but it doesn't actually have anything selected? I'm a bit of a newb when it comes to rigging so I'm not really sure what to do.
I've attached the scene if anyone wants to have a look.
