A product that has a far superior approach to surfacing
"Solid Edge shatters the barriers of traditional modeling
systems, combining the flexibility of nonhistory based
modelers that appeal to industrial designers with the
engineering benefits of a history-based approach. While the
history-based paradigm makes perfect sense for solid
modeling, it creates unnecessary complications when it comes
to complex shape design. In contrast, non-history-based
modelers provide a more flexible modeling method, but at the
expense of automating the update of related model elements -
a key drawback in modeling stylized parts which often
require a significant number of iterations. An industry
first, Rapid Blue unites the advantages of each of these
respective modeling technologies. Unique to Solid Edge,
BlueDots provide a flexible system in which the order curves
are created places no restrictions on editing, yet provides
all the benefits of properly updating related geometry when
changes are made."
"Unsurpassed flexibility Industrial design is, by nature, a
creative process that involves a great deal of editing as
designs evolve. Curves are the foundation for all shape
modeling, and it is critically important that they are able
to represent the desired shape and be highly flexible in
their editing. Recognizing this, Rapid Blue provides unique
"shape-preserving" curves, which encapsulate in their
behavior the ability to preserve their general shape
characteristics such that your original design intent is
built into each curve. For example, if a curve is convex
along its entire length (as many consumer product designs
main faces are) it will remain convex through all but the
most extreme edits. As a result, you save significant time
when creating and editing designs using shape-preserving
curves, and experience less fatigue and frustration as Solid
Edge automates an otherwise highly tedious process. "
"Evaluate more ideas in less time Engineers and designers all
design in an iterative manner, and this is truer in
industrial design than anywhere else. Because the style of
the part is a key component, you explore many more
alternatives. And the subjective element of industrial
design calls for the ability to make changes with continual
feedback of the results. With the Dynamic Edit capabilities
of Rapid Blue, you can edit your designs and see the results
instantly as you drag your cursor on the screen. All design
intent and history is preserved, and the graphics update on
every mouse move. This unique Solid Edge feature means that
more iterations can be tried in a shorter time, improving
product quality and acceptance. For the first time, you can
now interactively tweak highlight lines and see the effects
on all downstream rounds, fillets and blends."
"Your designs typically evolve over time, particularly given
input from the various players as they see the design
progress. For example, after review, it may be decided that
more flair is needed in one area of the product - a change
that can only be achieved by swapping a simple arc for a
more flexible curve. With traditional systems, this would
require a significant amount of rework, including having to
manually repair the history tree if the change is severe. In
contrast, Rapid Blue presumes that change is necessary, and
that starting simple and adding further control later is a
"Convert to Curve and BlueSurf are two key technologies
enabling a truly iterative workflow. Convert to Curve
allows analytic elements, such as lines and arcs, to be
converted to NURBS with a single click. With no loss of
shape data, the elements become editable curves. Even more
importantly, this conversion does not destroy the
downstream work that has been completed. BlueSurf
acknowledges and accommodates the inevitable increase in
control required as designs progress. BlueSurf is the only
technology in the industry to incorporate sweep, loft, and
blend into a single simple- to-use command. So, when
appropriate, that initial simple sweep can be made more
elaborate without having to manually repair the feature tree."
Based on what you said,..
IronCad or Inovate (cheaper version)
Pro/DESKTOP (free or pay for the $1K support)
...either are very good, inexpensive and will mature.

"I'm looking for a cad system for my machine shop. Most of
the parts are simple(involve tap,drill, facing, pocketing),
occasionally we get some complicated parts). But not too
difficult that we can't handle them."
You need to be more specific.
How much of your business is receiving solid models from
other CAD/CAM systems ???
How much will you be drawing from scratch ???
"Basically what i'm looking for in a cad system is:
1.something that is easy to learn 2.will work on winxp"
That requirement can be met by almost all CAD/CAM systems at
"I'm not planning on getting the maintenance package for any
potential cad system, that we do decided to purchase, since
i'm only buying 1 license. And were a small machine shop."
This is typical of the approach that many small machining
job shops take.
A question for you. Do you understand *why* IronCAD is being
recommended vs. SolidEdge or SolidWorks ??? There are some
very important concepts to be understood behind the
recommendation for IronCAD and why IronCAD (and other
CAD/CAM systems not mentioned yet.) have a *far superior approach* for
a machine shop working with imported non-native geometry
than SolidWorks or SolidEdge.
hi everyone, thanks for all your replies. I'm definetly going to take
a look at alibre.
To answer some of your questions.. Most of the drawings i get are 2d
*.dwg autocad files, which i then import into mastercam. Mastercam is
a great cam package but i think it lacks in the cad department
especially when i have to create complex surfaces.
When the part shows some surfaces, i then take the 2d file and create
a 3d part and the round surfaces that need to be machined.
Sometimes the customer will send me an iges file, which helps me alot,
since i don't have to create the part of mastercam. all i have to do
is the toolpaths.
Yeah so to answer your questions 90% of the files i recieve are *.dwg
while the remaining 10% are iges files.
But for this need it might be the best answer ... and he may already
have it but just lacks the IGES translator bit.
The data you are working with and where it comes from is important,
as is your end result.
As he's machining things I doubt he needs a parametric modeler to try
design iterations. ALL he probably needs is a way to work (well) with
the data from his customers, who seem to use AutoCad .... and then
transfer the data to MasterCam IIRC <shrug>.
Is AutoCad so much more expensive than SW?
....and if he does buy AutoCAD, he still does not get the surfacing he needs
Once again... why would anyone want to deal with Autodesk if they did not
have to. Based on what Adrian has posted, I see no reason that he has
well recently i got a dwg for mold i had to machine, and mastercam was
unable to create complex surfaces. So i think i need a good cad
package that can let me create complex parts or molds easily.
Can autocad do this?
AutoCad (specifically, Adesk in general) is at the bottom of the barrel for
such things. Just a bit of speculation if you consider the software purchase
a long term investment; Inventor's dwg support is so abysmal one would think
Adesk is trying to kill the dwg legacy themselves. In a very few years ...
Did you ask the people who gave you the dwg if they could give you the solid
or surfaces? I would think that translating the surfaces would be much
easier and higher quality than building them yourself.
Tripod Data Systems
Ofcourse i did, i would rather do "the least amount of work" that i
could possibly do. Unfortunately this specific client only has
autocad. And also we get the most amount of work from him.
One of our other clients has Pro/E, so all his part files are iges 3d
files, and much easier to work with since i just have to create the
toolpaths in mastercam.
"One of our other clients has Pro/E, so all his part files are iges 3d

If you go with IronCAD they license the PTC Granite One kernel so
you don't have to go the IGES route. IGES is the least desirable way
to import anything.
Further, IronCAD has the best integration with Rhino of *any* CAD/CAM
package. Also from what I'm told IronCAD 7.0 will have major surfacing
capabilities added to it. On top of all this, IronCAD offers far better
editing of imported geometry and because of this IronCAD does not even
bother with a FeatureWorks type of product.
