Move point

I have a problem while using "Move point" in GiD 12. I expect that moving point will change adjacent geometry properly (lines, surfaces and volumes containig this point to be extruded). However, surfaces and volumes behaves really strange.
The video with the bug is here: https://drive.google.com/file/d/1fSGvUX ... sp=sharing

I'd like to change volumes like in Autocad, see the link:https://drive.google.com/file/d/1Q4qK4f ... sp=sharing
Is there possibility like this?

The 'move point' tool cannot be used to do thing like you want
(e.g. deformate the surfaces of a volume to create a chamfer)
It must be used only for 'small' displacements, to join 'closest' parts.
If do you move a point, its curves won't be deformed linearly, like are you expecting with AutoCAD.
In general the lines are curved NURBS, and its 'interior' will be deformed somehow to force the new coordinates of the moved end and preserve the other end point, and also the surfaces will tried to be deformed a little to moreless match the new boundary
concluding, a straight line won't become linear, and a planar surface won't become planar.

In your case, the final surface of the chamfer has a interior part that become not planar.

You can force a 'rebuild' or its inner shape with
Geometry->Edit->Rebuild surfaces from boundary

and select the surfaces distorted by the 'point movement' to be re-created with a new shape, defined only from its boundary lines.

Thanks, escolano! This is exactly what I was looking for! After Rebuild all boundary conditions and mesh settings applied to the surfaces were not corrupted.
