Please Help!!

I feel like a moron having to submit this post and I thought I knew how to LOFT and/or sweep...but apparently not. I'm having a lot of "pinching" when I generate certain shapes with loft or sweep. Its always around corners where linear meets radius as you can see below. Are there "rules" to lofting that I'm not following?. Does this have to do with my vertices (which are all welded by the way) Please someone help. Thanks

your shape must be smaller than your radius to avoid pinching.

 

when you have a 90 degree angle your radius is 0, so you can not avoid pinching in that case (i think).

 

it may not be noticeable in the rendering, if it is i would create the lofts individually and stitch them together as editable poyls

It's just like if you chamfer too much, the geometry has no choice but to deform.

 

To 'fix' the mesh error, you could convert it to an editable poly and weld/target weld/move the verts.

 

But I'd do what Dave suggests.

all you need to do is one of the following:

 

• use a path/spline on the opposite side of the loft and apply the loft in the opposite direction (use the Outline feature on the current path to do this). this will prevent the corners from overlapping
   
  
• manually dictate where the steps/vertices in the path will go and place them in a way that prevents too many from ganging up around the corners. i recommend doing this for any loft and any object type, and the first suggestion can also be used for extreme cases
