Cannot Weld polygon

[Anonymous]

Hi guys i dont know how to weld those polygon shown in the paint screens... Can anyone tell me how i can do it?

I want to create a dual interpenetrating cones with those cracks all the way up, this will be a transformer frame that i will 3d print.

To weld those edges midway, do this:

First, switch to Uniform Scaling by holding (long click) the Scale-button (first option).

Then set your Transform Center to the Selection Center by holding the Use Center button (middle option).

Now scale those edges towards each other.

Translate this Edge-selection into a Vertex-selection by Ctrl-clicking on the Vertex-button and Weld them carefully.

thanks for trying to help, but i tried what u told me to do and didnt work it doesnt seem that this problem i have is able to be welded or bridged... i will leave the file with my project attached if anyone wants to see. It probably is a easy fix but im new in 3d modeling so i dont know.

If I understand you correctly you want to connect two internal edges groups. I think this is not possible in Max, as one edge is limited to connect two faces. Your operation would result to one edge being connected to 3 faces. You only can connect external border edges. 

If you want to create a geometry for 3d printing then you need to decide if you need the internal hole cylinders. If you need them then the cylinder connections would be a standalone cylinder. The printed result would be 3 pieces. If not you can simply deleted those internal cylindrical faces and then you will be able to connect the borders resulting a single 3d piece.

i undestand what u are telling me, but i wanted the internal cylinder for extra support. Well if there is no way of doing this with 3ds max, im gonna try other softwares. If anyone knows some software were im able to do this please tell me.

I don't know any 3d program that allows an edge connected to more than 2 faces. Probably there are cads programs that allow it but it is not normal is visual 3d programs as Max, Zbrush etc.

In any case 3d printing needs water tight geometry without internal geometry. This is compatible with one edge only connected with two faces. I don't think there is any shape you can imagine for 3d printing that can not be done in Max.

If you want an extra cylinder then it should be a different object. But if you want that cylinder being part of the other two then simply remove the internal faces you dont need and make it a single piece.
