Scale question? How not to scale an entire solid object(s) but just a part of it?

Hi,
I just finished my basic shape of a pillar, added some detail such as holes and pockets...
And now i figure out that a part of it should be larger, and i'm stuck!

It's very easy to scale an entire object, but how can you scale only a part of that object and leave the rest untouched?
I think that what i'm looking for is parametric modeling...
But i think that my example below is something that doesn't necessarily envolves parametric modelling.
I'm designing a sort of pillar, and the bottom needs to be streched a bit.
I guess that i could cut the object in 2 pieces, move them apart, extrude on of the pieces and boolean union them back together.
But i was wondering if there is a tool in Moi, that alows you to strech/scale between 2 points on a selected object???
When i was using sketchup i could do this i a second, but in moi seems a bit more complicated ...

Hi Glenn Claes,

Try this method, it should work.

1) Select your part
2) Unjoin all its surfaces
3) Show control points of all selected surfaces
4) press "Esc" to deselect every surface
5) select the desired control points
6) move them to do the modification you need
7) press "Esc" to exit control point editing mode
8) re-select all the object's surfaces
9) Join all together to obtain a solid again

I think that if your model is simple this steps should work.

Nice Day,

Marco (mkdm).

Seems inside Sketchup you must use also some specific plugins! ;)

Hello Glenn,

didn't test it, but one of Maxs scripts can help here http://moi3d.com/forum/index.php?webtag=MOI&msg=6674.267. It should do the same what Marco described.

Have a nice day
Karsten

Hi Glenn Claes,

...you're welcome.

One last suggestion...

In the event that some or all surfaces of your model are trimmed, then maybe there's one additional step
to follow in order to better achieve the wanted result :

(link to my previous post http://moi3d.com/forum/index.php?webtag=MOI&msg=7982.2)

1) Select your part
2) Unjoin all its surfaces

2B) Execute the "ShrinkTrimmedSrf" command on all the selected surfaces
2C) select again all the surfaces

3) ...
4) ...

Nice day,

Marco (mkdm).
