Draft Message

[ruger2]

Goooooooooooood Morning!

 

We received 2 models from a company. When I convert the Iges file I get a message......

 

Draft Message

Warning - Drafting entity contais forward pointer - Associativity removed.

 

I did a search on this forum and found a message from 2004 with the same problem but didn't get too much from it. The model looks ok..... will it be alright to toolpath?

 

Also when opening 1 of these models I got a message.......

 

Warning - Zero length spline

 

Any take on this?

 

I am running Version 9.1 MR0105

 

Thanks,

The Draft message is in reference to a drafting dimension or something. Should not affect the actual model (wireframe and surfaces) at all.

 

The second one is something I get occasionally. Typically I ignore them. It is basically a calculated spline that is smaller than the tolerance of the conversion.

 

I generally make a solid from the surfaces and interrogate the solid to make sure all is well.

 

If you can't do that, and you need wireframe. I would suggest deleting the wireframe garbage that IGES typically gives you, then Create curve all edges all surfaces.

Thanks MLS,

 

Kannon sent me an email and did pretty much the same thing. I am going to do some trial and error as you guys suggested and learn something.

 

I appreciate your help.
