Hi Ibon,

Paraform is very good at dealing with parting lines, please see the email
response below posted on behalf of Paraform.

In addition, Paraform will allow you to slide the parting line around
anywhere on the part surface at will, and will also help you intelligently
set the pull direction, and can automatically correct undercuts. In fact it
can do this on a polymesh (ie: an STL) which allows you to automatically
correct the undercuts/draft issues at the local problem area (the individual
triangles causing the undercut), without adversely affecting the rest of the
surface shape or overall continuity, which can be difficult in most CAD
environments. We use it regularly here at Slingshot Product Development to
launch a wide range of products from Automotive/Aerospace to
consumer/electronic products.

As a Value Added Reseller of Paraform software, our Slingshot associates
would be glad to demonstrate how we've succesfully applied Paraform for
numerous applications. We can easily demonstrate this over the internet or
onsite, and can also offer this as service work. For the full range of
services/products, and more information, visit
or feel free to contact us.

  Good Moorning,
  This is my first email to the list and first of all I would like to
  introduce myself. I work in a R&D center located in the north of spain
  our main activity is based on materials research eventhough we work in
  another areas such product development.

  I am tring to find a good and fast tooling design software. My biggest
  concern is related with parting lines and undercuts and in this way I am
  trying to find the software that approches more to do this task
  automatically. If anybody could give a clue, that would be great.
