Unable to thicken the surface

1-IUFH3H Apr 14, 2009 8:01 PM

I am modifying a model that has a thickened surface. After I make my shape change, I am no longer able to create a thickened surface. I get the "Unable to thicken the Surface" error. It shows me a preview, but does not complete the feature. If i do not add the surface that has the shape change in the knit, then the surface is created. Can anyone help please??

Sure, just upload the part after the change, and attach it to your next message. Make sure to .zip it first.

  Thai emailed me the file, so I have attached it. I can't look at it until tomorrow morning though.

I'm not sure why it doesn't work for the .040" thicken, but it works for up to .0326"

The reason it won't thicken is probably the degeneracy. Check the faces using Face Curves. Oh, and this:

Minimum radius of Curvature: 3.93701e-007 in

Do a Tools, Check on the model, and you see this right at the degenerate point. That's your problem right there.

I hate to sound so crass, but this problem is discussed at length in my book and in some blog entries.

  Thank you gentlemen!! To sum it up, the determining factor for surface thickness creation is going to be the radii of your curves relative to the interested thickness, correct? So, this is very similar to the allowable bend radii when dealing with sheet metal. Thank you all!

Hi all,
I'm researching about effect of new materials on bumper fascia, I downloaded one CAD file form Grabcad.com, Unfortunately, It's in surface type, and I'm a new guy in Solid Works. I trully need your help. It's always say " Unable to thicken the surface" I try many ways but it didnt work.
Here are my file: https://www.mediafire.com/?b9i5z6xfag1775d ,
Thanks in advance

Roll back in your feature tree just below Surface knit 6, then edit your Surface knit 6 to include the "Surface-loft10" , then roll back down in your feature tree. your part will thicken with thicken22, thicken12 can be deleted. Tom
