3D Modeling Techniques 
ZW3D vs Solidworks Lesson Four
Primitive Shapes & Sketching

I saw some Fusion 360 exercises online and I decided to compare ZW3D. It quickly turned into a study in modeling techniques. I have created fifteen "ZW3D vs Fusion 360",  six "ZW3D vs Solidworks" and one ZW3D vs Creo lessons to show the difference between ZW3D and the two programs and my modeling techniques. I found the Fusion 360, Solidworks and Creo presenters 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 ZW3D'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 ZW3D vs Fusion 360, Solidworks and Creo lessons, there are some very stark differences.

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 ZW3D. I again show modeling techniques that can easily be streamlined even within their existing system. I call it feature based design. Please review a few of the above ZW3D vs Fusion 360 lessons, there are more very stark differences.

SolidWorks | How Can I Draw 3D Part (exercise 18)

Here is the drawing if you would like to give it a try.

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. ZW3D is all top down due to the Multi-Object environment. Creating mating parts is a cruise. But modeling is just one aspect of a well designed productive 3D CAD system.

Solidworks 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.

ZW3D vs Solidworks

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 ZW3D support to create one. They are very good.

The modeling technique is hugely responsible for the level of productivity. Those of you that are only trained in the sketch, sketch, constrain, constrain world are truly limited by not using the freedom of feature based design, 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?

These lessons have actually turned into exercises in modeling techniques as compared to showing a more productive CAD systems. Again, I say, there are many different ways to model a part. I see with my exposure to direct edit modelers like CADKEY, I rarely sketch like you see the Solidworks fellow doing. I have always created my basic sketches by mostly creating offsets and extending and trimming or. It seems to be much easier. I never put in a fillet that can be created later. What do you think?

We are already in millimeters.

So lets get started.

This part takes 8 simple steps including one sketch!

Note: Pro/e clones have been starting with the sketch for almost 30 years. Even today the sketch is the only option in most programs. ZW3D is very similar to Solidworks  by being based on sketching. The added primitive shapes option can increase productivity 30%!

We will start by inserting a primitive block and size it.

Note: Designing with primitives is an added feature to making "Feature Based" even more productive. This is one of the reason I have selected IronCAD and ZW3D to represent.

We add the fillets at this level. It is not much time saving, but is shows you a "Feature Base Modeling" mind set that focuses on streamlining your modeling.

We insert another primitive block and set it to remove and size it.

Note: You have four primitive block options. It takes a bit of playing to get a handle on how they work, but you can see the incredible productivity advantages. Design with primitives gives you more control over your design than with sketching.

Insert another block and size it. Designing with primitives reduces the tediousness of "Sketch Modeling", making design much smoother and a more pleasurable experience.  

I noticed that the SW presenter sketched this from the bottom plane. I would have used the face as the sketching plane. But it is six of one and a half dozen of another. It is just interesting watching a different modeling process.

We now put in the fillets. This was the first time I have seen a Solidworks clone user create a full radius with a command instead of sketching it.

We have to sketch the slot. Lucky ZW3D supplies a 2D slot option.

We extrude the slot and add the hole and we are done. Again the SW presenter is still sketching.

There you go, an adventure in the highly productive "Feature Based Modeling" with primitive shape design.

This is another stark example that feature based modeling with a mixture of primitive solids and streamlined sketching can increase productivity 5X in this case. I usually estimate 5X increased productivity in conceptual design and 10X in changes, and I believe I am being conservative. ZW3d can edit most of the Solidworks clone parts and assemblies faster than it can be done in the native CAD system.
