Translate face

Question

Hi,

I'm struggling with what seems to be a very basic task. My goal is to achieve a split/translate operation resulting in the bottom model of the attached image. However, splitting and moving using split and comp methods gives me the upper result. Any ideas how to keep edges connected while translating a face?

Any hints much appreciated!

sadly, this is not (yet) possible.

OK, not much for me to do then. Appreciate your effort to help me!

hi Magnus ..

ah, I know what you want, basically moving components like vertices or edges.

sadly, this is not (yet) possible. in CGA, you can either split or move, but there's currently no way to 'select' a part of the shape and transform it.

( I have wished for such a feature before too. )

what we can do right now is : put it to the ideas !

- if your 'object' is an inserted asset, then you would want to translate BEFORE a comp(f) because the object then is still 1 mesh. after a comp(f), you get n objects.

Thanks again for trying to help me Matthias!

I'll try to narrow my problem down. Basically, the only thing I want to do is the following:

1.   split(v, unitSpace, 0)
  {
   '0.2 : A. |   
   '0.6 : B. |
   '0.2 : C.   
  }

2. Translate the middle face (B) in Y-direction while still keeping it's shared edges attached, resulting in the two outer faces (A, C) leaning towards the middle face. The wanted behavior is that of an 3d-modelling application, when you select a face and translates it, it keeps its edges connected.

Is this doable in CityEngine?
