Maya for 3D Printing - Rapid Prototyping

In this course we're going to look at something a little different, creating technically accurate 3D printed parts.

Hi, I have a question on the bridge tool and I'm going to use a cube as an example. Why does this happened when you smooth it?

It looks like when you have faces on top of each other but its not that, no overlapping edges or unmerged vertices either. Im not trying to build something with that cube Im just using it as an example.

Why does this happen cause when I move the edges they seem to be attached, It is a error I guess!! Thanks again.

When you move the edges, you are actually moving the attached verts, which are shared by both edges, so you can't pull them apart the way you can with separate verts. Just select all the edges and do a merge. Make sure you turn on show border edges in your prefs so you can see when they are merged or not.

No it's not an error. When you bridge edges in maya it does exactly that, it bridges the edges you select. Some applications like max bridge AND merge adjacent edges. Maya does not do this. You either need to use "fill hole" or merge edges afterward and that is not an error it's just the way maya was designed to work.

btw if you go to your preferences and set the border edge thickness to say 4.0 by default then any open edge will be very easy to spot. I use this as my default setting.

ctbram, I try to make my border edges bigger but when I change the value to 4.0 it doesn't change the size. Maybe I'm doing something wrong.

windows > settings/preferences > preferences
then go to polygons
then set the highlight border edges to 4.0

I also like to turn on soft/hard edges
and hight creased edges.

If that does not work then you most likely are having a graphics card issue.

Yiep!! I did that and it did't work. My graphic card: Nvidia GeForce 9400M 512MB Nvidia 9600M GT, What do you think? Is it enough? I really don't know much about graphic cards.
