mold design help for compression molding



I have a fin part and mold part but I need to create a second mold that will be basically the same a the one I have but with a wall thickness of 1mm more so that I have space between the 2 mold to fit my carbon fabrics.

I tried to use the thickness function in catia but it does not work and always give errors, most probably because of the shape. I unfortunately have no idea how to solve this issue and would require some help.

anybody can have a look at the parts and/or explain what is the way forward?

examples of what I mean

Go up in the tree and add the Thickness to the aileron (fin) before it's removed from the die block.

(and thanks for including the interesting pictures!)

I'll try to help you; can you tell us what the error messages say? Also, a picture of the CATIA tree will help understand how you've created this model.
