Some easy questions about the ft&a 2

[RtotheJ]

Hi! I'm trying to wrap my mind around model based definition, using the functional tolerancing & annotation plug in for Catia V5 (r18). Most of the things I want ft&a to do, it does without problems, but I've run into a few walls I hoped you all could help me out with. So, without further ado; my questions:

1. Is there really no link between the dimensions in the catpart and the dimensions you define with ft&a? Eg. if I make a 6x6x6 inch cube, dimension it with ft&a, then change the model to be a 5x5x5 inch cube, is there any way to get the annotations to auto update to the new actual size of the cube?

2. I've been trying to add masking [for surface treatment] to some surfaces, but I just can't get it to work. I've tried to add a new body in the part that is supposed to be hidden, and then display it with a different colour in just one of the captures. It almost works, but after I've displayed the masking capture, the body does not toggle back into hidden, even in other captures. Any suggestions about what I'm doing wrong, or to another solution to this?

3. How do you handle directions on geometrical tolerances?

If you got this far: thank you for your time

sorry I didn't spend more time but here are comments about question 1.

It works for me in R18 SP3 HF36. I am using FTA at the part level and I do modify the sketch and exitit then the FTA dimensions are updated to new values.

If I use FTA at the product level, then after I exit the sketch I have to activate the product level in order to have the FTA dimensions updated.
