ZW3D vs Solidworks vs Creo Lesson One
Multi-Object Environment
Top Down or In-Context Modeling

I have created fourteen "ZW3D vs Fusion 360" lessons to show the difference between ZW3D and Fusion 360. It soon turned into a study in modeling techniques. I found the Fusion 360 presenter was wasting massive amounts of time with overly complex sketching procedures. I was so unimpressed that I decided to model an assembly, showing my modeling techniques plus ZW3D'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 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.

Please watch a Solidworks user model this part!

He creates one part? It is three parts.

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. 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 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.

ZW3D 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 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 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 procedures. Don't have any do you?

These lessons have turned into exercises in modeling techniques as compared to showing a more productive CAD system. Again, I say, there are many 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. I call this Streamlined Sketching. It seems to be much easier. I never put in a fillet that can be created later. What do you think? 

Let's get started!

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

This is an inseparable assembly not a part. So we will create a new multi-object file. This is one of the functions that make ZW3D much more productive. Offering the ability to have your project including all of your parts and sub-assemblies in one file. PDM would not even be a problem. Plus the drawing is also integrated.

We will create the top assembly and name it Bracket Assembly

Now we insert  the first component, the Bracket Right. I am showing you these step to present how we set things up in the multi-object environment. There are a few Solidworks clones that offer a environment like this but it is basically an after thought and not an integrated part of the basic program.

We can now start designing. We insert a block at X0Y0ZO, offsetting it .05 and size it.

We insert another block, locate and size it. I used primitive blocks to show an alternative to sketching. You have the option to use either function, as you get experienced you can decide which is more productive. For me "Feature Based Design" is very easy and usually my first choice.

We will add the fillets and hole. I could have just as easily copied the first block.

Now for the twist. This is a great command. We need profile curves to generate the loft and creating a curve list is an option in the command. So it is quite easy.

We are done with the first bracket

We will now create a new component. We will just copy the first bracket and name it Bracket Left and locate it at X0Y0Z0.

We open Bracket Left and start to work. We first delete the twist. There is more to this assembly than meets the eye.

Now we mirror move the vertical end using the YZ plane. This is the reason I offset the first block.

We move the horizontal end into place.

We are now ready to add our twist.

We are now done with our two brackets.

Now for the spacer. We create a new component under Bracket Assembly.

We just leave it in edit mode and insert a block at X0Y0Z0.

We put in the fillets and hole and we are done with the assembly.

Here is the final assembly. You can see how easy it is to design an assembly in one file.

Here is an exploded view.

We select 2D sheet and create the associated information document (drawing)
This is integrated in the same assembly file. Imagine how having this feature could simplify your PDM?

You can see the drawing included with the other parts or subassemblies in the Object Manager.

Here is the original drawing.
