change edges with rhino 4.0

[federicom]

Hello, I would need a support for rhino.
changes are made on a 3d iges (see screen shot attached). the file was generated from a laser scan that I carried out on the physical object. subsequently the client asked me to make the edges alive, something impossible to do with geomagic studio 10, given its poor ability to manage the iges. I therefore imported the file on rhino with the intention to model the “cordolo” of connection between the trimmed surfaces that I indicated in the annex. Premitting that I am not at all a rhino expert (it is the first time I try to use it), I would particularly need to make the curvature of this radius connection equal to 0, but I can't.

Can anyone give me directions?

Thank you in advance.

you can try to combine surfaces (command _untrim)
and then extend them (_extendsrf) if they do not intersect each other already.
then after you have to retrim (_trim).
to say it is easy, to do it a little less. You have to make the edges coincide.
I recommend, before you add the surfaces, to copy the edges ( _dupborder) or the individual sides (_dupedge) and then use the curves to cut them out.
another command that can be useful to you for your purpose is (extendcrvonsrf) that extends a curve that already lies on a surface to the edges of this.

Let me know.

hi, with spaceclaim (integrated to rhino) you can do interesting things: http://www.caedevice.net/spaceclaim/video/spaceclaim2009_defeatuirng_20090219.wmvif you send me the file (3dm or step, or both) I make a test (do not worry about the fact that we are agency of... ) and I put the result on the forum.
