Force the model to refraesh

[motish5]

Hey
I made a script which add to the model a lot of faces.
But, since the real painting is made only after the script is finished, the result is a operation of drawing like 80 faces in one time, what make the SKP to freeze and fail.

How can I add to my ruby script a command which force the model to paint the new face immediately and not to wait till the end.

Thenk a lot
