3D Modeling Techniques IRONCAD vs Solidworks Lesson
Ten Streamlined Sketching/Feature
Based Modeling Two Similar Parts and AIDs:
When I introduce IronCAD's very
flexible design paradigm I have a hard time to get the Pro/e clone
users, like Solidworks and other programs, to understand the drag and
drop design paradigm.

new customers. Give it a try, this is a fully functional 30 day
evaluation with all of the native translators so you have access to
your legacy engineering information.
I saw some Fusion 360 exercises online and I decided to compare
IronCAD. It quickly turned into a study in modeling techniques. I have created
many comparisons to Fusion 360, Onshape, Solid Edge, NX, Creo,
Catia and Inventor
lessons to show the difference between
IronCAD and my modeling techniques. I found the presenters working
identically wasting massive amounts of time
with overly complex constrained sketching procedures. I was so unimpressed that
I decided to model the parts or assemblies showing my modeling techniques plus IronCAD's superb design system.
3D Modeling Techniques Defined
Many of these modeling techniques can easily be implemented even
within their existing system. I call it Streamlined Sketching and
Feature Based Modeling. Please review a few of the above IronCAD
comparison lessons, there are some very stark differences.
While creating 3D models from drawing is the very best
way to learn 3D CAD and maybe some design techniques it does not
expose the designer to the design flexibility necessary in design. IronCAD is all top down due to the single model environment.
Creating mating parts is a cruise. But modeling is just one aspect of a
well designed productive 3D CAD system.
is a marginal 3D CAD system based on the dated Pro/e (Creo) history
based modeling system. I have sold this product years ago and found
it, like all of the other Solidworks clones, not productive enough
for our engineering department. We use what we sell. That gives us
the experience to effectively support our user base.
I would do a
video, but I really am not good at it. So I will show you step by
step. I will try and get IronCAD support to create one. They are
As with my Ironcad vs Fusion 360 exercises
I have found the same problems with Solidworks. The modeling
technique is hugely responsible for the level of productivity. Those
of you that are only trained in the complex and time consuming
constrained sketching world are truly limited by not using the freedom of
Streamlined Sketching and Feature Based Modeling, that is available in even the most
Solidworks-ish of CAD systems. If your
designers are designing in these very unproductive and time
consuming processes it might be time to review your standard design
processes. Don't have any do you?
Let's get started!
You will see
with Streamlined Sketching and Feature Based modeling is much more
productive and flexible. It gives you a more real world feel to
your design process and is a much more pleasurable and productive experience.
We will start with -1 Bracket
We set the units to mm
and drop a block from the Standard Shapes Catalog into the scene and size it.
Many of you
Solidworks and similar system users will notice we don't have any planes available.
IronCAD is not based on defined planes. The plane is part of the the
Note: Why does IronCAD
call it a scene instead of a workspace? IronCAD was first released
as a graphic design program called Trispectives. It still has much
of the graphic design functionality. It truly is a wonderful mixture
of professional 3D CAD and graphic design, which puts it in a much
more flexible category as compared to the very mechanical
engineering focused Solidworks clones.
We now drag and
drop a Cylinder to the mid point of the aft edge of the block and
size it. This makes the move of the cylinder to the correct location
an no brainer.
the Triball we move the cylinder into the correct location and
drag and drop a block onto center of the boss and size it as shown
We drag and drop a cylinder at the center of the boss and size
We drag and drop a on to the aft block and size it.
We pull the two blocks together to create the common edge
Now we create the center rib with two blocks and size them.
put in the blends
for the holes. For the hole in the boss we just drag and drop a hole
cylinder to the center and size it. But for the two counterbored
holes we will use the Custom Hole Tool. We drag and drop a Custom on
the mid-point of the face and size it in the dialog box.
using the triball we locate the hole using the "Edit Distance from
using the Triball we will mirror link the hole. We move the Tribal
to the mid-point of the part by selecting the space bar, onces set
we will again hit the spacebar that makes the Triball active and
select the inner relative axis and use the mirror link option.
we just add the blends. We turn off the catalog. Usually we use it
in autohide mode.

part was done with no sketching. IronCAD has robust sketching but
with IronCAD you usually design in a specific order. Now you can
always start with a sketch and go from there but usually your start
by dragging and dropping shapes.
Drag and Drop
Now to create a similar part -2
First thing we do is copy
and paste the part. I renamed
the first part -1 and the new part -2 and suppress, we can do this
because IronCAD is a single model environment.

deactivate the Triball and set it to global and locate it to the
center of the boss and move it using the "Edit Distance from Point".
We rotate 10 degrees.
pull the blocks to the common edges,
unsuppress the blends. We have to edit the 2mm blends as did the
Solidworks presenter. We are done with the part.
Now we are ready for the AIDs (drawings)
We have two files for the two parts and AIDs.
Here is -1
we create sheet 2 and set it to configuration -2 Bracket
another stark examples
of how Streamlined Sketching and Feature Based Modeling utilizing IronCAD's drag and drop of smart editable
intellishapes from a catalog and
the use of the Triball can increase productivity easily 5X. I
usually estimate 5X increased productivity in conceptual design and
10X in changes, and I believe I am being conservative. IronCAD can
edit most of the Solidworks clone parts and assemblies faster than it
can be done in the native CAD system.
Give me a call if you have any
questions. I can set up a skype or go to meeting to show this part
or answer any of your questions on the operation of IronCAD. It
truly is the very best conceptual 3D CAD system.
