Julian, do you have solids ?

[ObrienDave]

Julian,

Unfortunately, you can not modify a fillet SURFACE.
You can copy, translate, offset, extend the edges, and a few other things to most types of surfaces.
You can not modify the curvature of an existing surface except for scaling.

You can, however, make a new fillet surface over the top of another one.
In Mcam9, Create surface, fillet, plane/surf or curve/surf or surf/surf, whatever the case may be.
I do not recommend using the trim surfaces option because I prefer to keep as much of the ORIGINAL geometry as possible.
This way some engineer can not say you destroyed HIS part.
But that is another rant for another day.

You may have to change the NORMAL of the surface to get the fillet on the proper side.

Please review the attached ZIP file.

Please remember to re-select drive surfaces.

If you have the solids option, an easier way to do it is to make a solid of your part.
Not from surfaces, but from scratch.
This way you have the, for lack of a better term, "history" of the solid construction.
This makes it REALLY easy to modify just about anything in the model.

In my opinion, Mcam solids is a subset of SolidWorks.
Mcam solids will do about 20% of what SolidWorks can.
If the solids manager shows ONLY a body, then it is impossible to modify EXISTING fillets.
You can ADD operations to the solid such as, holes, add bosses, put new fillets at SHARP corner intersections, but, you can not modify EXISTING fillets because the solid is ONE body.
Anything YOU add to the solid can be modified.
If you are not familiar with creating solids, the easiest way to learn solids is to do it just like you would machine it.
Start with a solid block and cut it using geometry.
Of course, there are easier ways to create complex solids.
But start with ways that are familiar to you.

Attached is a solid of your part without all of the IGES junk.

Matt,
Here is my opinion on surface machining solids from an earlier, pre McamX, thread.

Dave, how would i do this if i wanted to create a 5mm fillet over a 3mm fillet?
Thanks Julian

Julian,

Please re-read the above message.
I was in the middle of editing.

Dave,

Been very busy over christmas and forgot to thank you for all your help with
this i appreciate it.

[ObrienDave]

Your quite welcome.
Glad to be of help.
