Mirror Face? (the face in the mirror)

Dwight Livingston Oct 16, 2007 1:39 PM

I tried to mirror a face in a fairly complex part I have. I selected one face and a plane to mirror it about. I got an error message saying . . .

One or more features used in this mirror feature are longer in the model.

What? I just selected them. I banged on it a little, trying out options, but nothing made it work. So I started a new, simple rotated part and tried to mirror one face in that. I got an error message saying . . .

Could not attach patterned faces to the solid to form a closed body.

So I first deleted a face so I didn't have a solid body and tried again, but got the same message.

So does Mirror Face work at all?

Thanks.

According to the help menu, the main use for mirror faces is to mirror imported geometry features that aren't really parametric features. The faces must be able to enclose watertight space across the mirror plane. To just mirror a face that wont' intersect a solid across the mirror, use Offset Surface to copy the faces and then use Mirror Bodies to mirror the resulting surface body.

  Thanks for the work-around, Mark. It'll do the job. I hope they fix this quirkiness sometime.

    Then what would we have to talk about?

      i heard about this at one of the last user group meetings iattended. i always use knit surface to copy faces of a solid bodyfor fear that offset surface might have a dimension inadvertentlyapplied to it. but i guess it's six one way half a dozen the other.

        I like to use Offset Surface to copy faces as I have the option TO add a dimension should the need arise, and also to keep straight in the Feature Tree what is a copy and what are surface bodies getting knitted together.
