5.pycatia_dynamic_color_change

[evereux]

The CATPart provided with 5.pycatia_dynamic_color_change was created with CATIA V5 R32. Users with older versions of CATIA V5 will not be able to open this part.

I think the CATPart created tin the earlier examples would be a good example to use and refer to instead.

Also,

# -------------------------------------------------------------------------------
# Step 4: Select the main PartBody
# -------------------------------------------------------------------------------
part_body = part.bodies.item("PartBody")
selection.add(part_body)

I think would be better written as

# -------------------------------------------------------------------------------
# Step 4: Select the main PartBody
# -------------------------------------------------------------------------------
part_body = part.main_body
selection.add(part_body)

Only because the main PartBody might not be named PartBody. Extremely unlikely, but it can happen. :-)
