IronCAD vs Solidworks vs Creo Lesson Five
Single Model Environment
Top Down or In-Context Modeling

When I introduce IronCAD's very flexible design paradigm I have a hard time to get the Pro/e clone users, like Solidworks to understand the drag and drop design paradigm.

I have created fourteen
"IronCAD vs Fusion 360" lessons to show the difference between IronCAD and Fusion 360. These lesson are a study in modeling techniques. I found the Fusion 360 presenter was wasting massive amounts of time with overly complex constrained sketching procedures. I was incredibly unimpressed. Look at my highly productive proven modeling techniques plus IronCAD's superb design system.

I was quite pleased to have found these exercises from a Solidworks dealer and thought I would show the difference in my modeling technique plus the highly productive modeling method offered by IronCAD. I again find modeling techniques that can easily be streamlined even within their existing system. I call it Streamlined Sketching and Feature Based Modeling. Please review a few of the above IronCAD vs Fusion 360 lessons, there are more very stark differences.

3D Part (exercise 17) Solidworks Tutorial

Please watch a Creo user model this part!

I have found this tutorial Video of CREO using the same demo. The presenter does not include the small spacer. But like the Solidworks presenter he makes one part, this needs to be separate parts. We train for creating functional parts not cartoons. Also the loft process is a bit more convoluted than the Solidwork presentation.

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.

Solidworks and Creo are marginal 3D CAD systems based on the dated Pro/e history based modeling system. I have sold both of these products 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.

Is 3D CAD Productivity an Oxymoron?

IronCAD vs Solidworks and the Pro/e Paradigm

IronCAD vs Solidworks vs Creo

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 very good.

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!

We are already in Inches. So we can start modeling.

This is an inseparable assembly not a part. IronCAD is a true single model environment, so we do not have to concern ourselves with the assembly and there is no special preparation, we just start modeling.

Drag a block from the catalog

We select one handle and edit the size of the block.

Now we will drag and drop a hole cylinder in the center of the block and size it.

We can minimize the catalog since we will not be using it for the rest of the exercise.
Now we will copy the feature and place it with the triball

We add the full blends or fillets

Now we select the two faces that are the basis for our twist.

We set the start and end constraints and set the vector length

Now we edit the match points to complete the twist

We now create the spacer using the extrude wizard and create a new part. Since IronCAD is a true single model environment you do not have to worry about any relationships with the parts. You are always designing in the assembly. Yes, you can have external relationship if required.

We project the relative edges and offset them .100. IronCAD smartly leaves the original entities highlighted so you can delete them.

We now have a complete sketch. Notice there are no constraints. This is what I have coined "Streamline Sketching"

Now close the extrude wizard and set the thickness to .100

We change the color of the spacer

We copy the existing part and locate it with the triball

We delete the twist and relocate the affected end.

Now we add the final twist as we did above.

Assembly done

Exploded view

We create the AID (Associated Information Document) (drawing). You can see both the AID and model in the same session. This is great when you are working with an assembly and individual parts.

Here is the original drawing.

This is another stark examples of how IronCAD's drag and drop of smart editable shapes from a catalog and the use of the Triball can increase productivity 5X in this case due to the simplicity. 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.
