Hey Norbert, that's a GREAT question!

This reminds me of a naval architecture question i saw elsewhere:

http://www.shipconstructor.com/...m/viewtopic.php?f=2&t=62

This one is highly applicable to what i will encounter soon enough, making flanges.

Currently, i've been making a profile of various sizes according to location in the hull. Midbody areas have thicker elements, and the fore and aft areas have thinner but more numerous stiffeners.

My thinking is that for this model, it may have to be broken down into zones or parts that remain (or are highly likely to remain) fixed in general, with the ends being "cut to suit" their terminations.

I was successful getting the cyan area to move (as it appears you did, too) to a more distant or a closer termination against plate and that saved me the work of extending beyond and then the need to trim back.

So, I'm not sure, but it may be that Tim & co would need to add some code to "maintain relative angle of (selected edges between two points (or more points?) but extend or trim distance of (profile edge) selected.

Alternatively, maybe a "stretching/retracting plane" of sorts can pass thru the part at the bounds of what is to remain fixed; everything in on the opposite sides of the boundary plains would be stretched according to either an angle referent or according to an edge that is allowed to move, so maybe the plane would be some infinitesimally small but discreet distance inward so the bottom edge stretched is of neglible length at the beginning of its own stretch.

Not sure if this thinking is making sense, but i'm firing it off before catching my bus.

Hello Norbert,

Without your geometry it is hard to be certain... have you tried a move face on the 2 face I have drawn red boxes around?

Unfortunately, this is the sort of tools I think would do something similar...

http://www.rhino3d.com/4/help/C...ds/Move-EdgeFaceHole.htm

I am trying to do the same in Rhino, but the commands/interface is taking some getting used to...

With history kept, in this example the curves used for the trimming of the solid, then editing the curves will update the model.

The "MoveEdge" will work in Rhino for what you want. If you cant find the tool, just start to type "MoveEdge" and a drop down menu will show and you can select the command, select the edges then move them (make sure you move planer to the object)

My mistake I meant I needed the angles to change.

"Shark FX for Dummies" more like! Complete with YouTube viddys!! It'll be the BOMB! :cool::cool:

Yes, what I normally do it that situation,is to open the concept explorer, then use the "deep select" tool to select any part of the object to edit. Then in the explorer tree, select the boolean object, that can then bring up the boolean object size which can be edited, or to move the boolean, I find it easier to go into one of the ortho views and use the nudge keys (which I have enabled in the preferences) and move the object with the nudge keys.
