Booleans difference problem

[Anonymous]

hi, i am following a tutorial.

I am supposed to indent a hole into the green piece in the shape of the grey cap while retaining the original mesh of the grey cap at the same time. The tutorial instructor uses plugin called crease+. I tried maya boolean difference tool but could not make a hole. Even in cases when i could make a hole, there seems to be unused vertexes around the edges of the hole made. When i try to connect the vertex of the hole to the other vertexes on the green piece, the mesh starts to tear up at adjoining edges.

Thanks in advance.

Are both objects closed. Boolean does work best with closed meshes.

Could you post a wireframe.?

hi,

they are both open meshes.

[Christoph_Schaedl]

you need more poly in the area where you try to bool.

and the small bool object needs to be closed in the intersecting area.

hi, after some trial and error i managed, but i run into new problem: when i try to connect the two selected vertices, the mesh become distorted.

Thats a normal behavior if you work with large ngons. Just connect all of them. 

Next time create some edges before doing the boolean.

hi, thank you for helping out. after whole morning trying this and that. The problem it seemed to me lied with the original mesh. This is because when i tried to do it with the previous increment maya file saved. I found out that i could perform the bool with no problem connecting the vertices later. I might had damaged the integrity of the original mesh along the way between the increment file 24 to 27. The only difference i could notice was that there was the pasted_cylinder in  the outliner in file 27. I accidentally mispressed some commands and that could had been the cause of it. Anyway, i am so happy that i could continue with my tutorial with my mesh integrity intact while completing the boolean step succesfully. Gosh!!!!
