Hey guys,
I'm trying to rotate a thin round edge about the x-axis for 90 deg to convert a 2d drawing into a 3d. Whenever I use a thick surface, rotation happens with no prob and the mesh is perfectthick_surface.jpg. The issue arises with the thin surface and the mesh is just not rightthin_surface1.jpgthin_surface2.jpg. Please take a look at the pictures and any suggestions to fix the issues are the most welcome. Cheers Ruben |

Hi Sijal,
Thank you for your suggestion. I meant that when I'm using a thickness of 2cm or above, I'm able to obtain the correct mesh. But when I'm using a thickness of less than 2 cm, I'm having the issues that I showed in the pics. For my work, a thickness of 0.4 cm is required as it consists of the solid material. I did close the region but I'm still having those issues. |

I've posted 2 pics online, one with a thickness of 2cm 2cm_thicness.jpg and one with a thickness of 1cm 1cm_thickness.jpg. Even though I change the toleance level as you can see, the meshing for the 1cm thickness is messed up.

Hi mate,
THx for your help. I did figure it out. The rotation with very thin edges of less than 1 cm needs to be at a smaller angle say 10 deg. Then increasing the number of copies to the desired angle of rotation should do the trick. I've posted a pic with a thickness of 1cm as shown and incresed the number of copies to 36 to create a 360 angle of rotation.Screenshot 2014-08-15 21.03.05.jpg |
