Hello,

I received an IGES file and I'm trying to extract some dimension from
it.

When I try the model it tells me "Could not create reference dimension
from current set of selected items.


I tried to create a drawing and dimension it and I get a message, "The
selected entity could not be converted into a line or a circular arc."

Does anybody know of a way to get these dimensions?

Thank you

BTW. I'm using SWX 2006

How about clicking endpoints? If you;re trying to get a radius value, 
try tracing over it with an arc.

Whew. Maybe we should let this place sink into the swamp.

I usually try to create a tangent line or other geometry off of tjhe
IGES data, and use these as dimension references.  Sometimes SW will
let you use the existing IGES geometry to create reference entities,
instead of letting you dimension directly off of the IGES geometry.

Turn on VIEW FACE CURVATURE. Then you can assess the model and get
some insight into which features are analytical and which are spline
based.

1. Try FeatureWorks
2. Try the measure tool
3. Slice and convert edges or overlay three point circles as needed.

PS: What is the source of the IGES file?

I think it's Alias <sp>

If you turn on face curvature display can you see faces with constant
curvature?
Are the features you want to measure showing up with a single color or
a rainbow of colors?

  You might want to verify the type(s) of entities you
are trying to dimension ...

Where's bong-kweer with his "seamless, unified, whatever..." ?

I'm sure with his vast knowlege he'll let us know how VD cam or VX cad or 
3dinkies or whatever can do this so well.  Long live global shape shifting 
and insane CAD-CAM jihad!!!
