3D Modeling Techniques 
ZW3D vs Solidworks Lesson Eleven
 Streamlined Sketching/Feature Based Modeling
 Two Similar Parts and AIDs: Single File

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 many comparisons to Fusion 360, Onshape, Solid Edge, NX, Creo, Catia and Inventor lessons to show the difference between ZW3D 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 '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 comparison lessons, there are some very stark differences.

Solidworks Cover Lesson 12

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 model 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.

Is 3D CAD Productivity an Oxymoron?

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 constrained sketching 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?

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.

Modeling Technique Note:

There are two similar parts. In IronCAD we have a single model environment, ZW3D offers a Multi-Object environment. As I started these parts I realized I would have two parts to define. So I will start with an assembly that include the two parts. I am wondering it this would also be a viable solution for the Solidworks clones, unless they are already doing it.

We will set ZW3D to millimeters!

So we open an new file by selecting a Multi-Object file type and name it MOUNT.

We will open a part and name it COVER. This will serve the purpose as the top file.

Under COVER we will insert a component -1

We can now start creating -1. We will insert -2 later when we are done with -1

Many time we start our modeling with a primitive shape, but we will start with a sketch on this part.

We create a sketch on the XY plane

We create our sketch. ZW3D allows you to put the entities in and define them in the same step. I use entities to construct my sketch. Here is the rough sketch, notice there are no constraints.

Notice where X0Y0 is, this is important in the creation of the sketch.

I clean up the sketch and add a 350mm diameter circle.

I exit the sketch, the part is made up of two sketches the second made from the first. So I copy and paste the sketch.

I will edit the new sketch by offsetting the entities. I will trim these up and exit the sketch

We insert a primitive sphere locate it and size it 340mm

Now we extrude the 2d sketch. We have the upper part of our shape.

We now insert a primitive sphere, locate it and size it to 320mm

We will extrude the first sketch

We now insert a primitive cylinder and size it large enough to consume the larger sphere.

The two shapes have to be combined then we put in the draft.

Now for the fillets

Now for the shell

We are done with the part.

Now for -2. We will insert a new component under the MOUNT Assembly. We will take the -1 copy it and name it -2 and locate it to X0Y0Z0

We open -2 and delete all of the features not required for this design.

We copy the 2nd sketch and edit by deleting the large circle. We will create an extrusion set it to remove.

Using the same sketch we will create a 20 extrusion and set it to add.

We will now go to the Direct Edit menu and select face move and rotate it 20 degees. It not only rotates it but is stays in same orientation.

Now we draft the faces.

Now for the fillets.

We shell the shape.

One more sketch. Selecting the inside face select Y as up.

Time for the AIDS. ZW3D is the only history based system with a multi-object modeling system with integrated AIDs. Imagine the PDM Problems this would solve.

While in the assembly I created these sheets with a right mouse click and selecting 2D Sheet so I would have the two sheets in one document. I will not go into the detailing process, but it is a relatively easy robust documentation system.

Now we are ready for the AIDs (drawings)

When you create a 3D model from a drawing you have to do a detailed AID to assure you have duplicated the drawing. You should also have someone check it if it is in a production environment.

All You Wanted to Know About Drawing to 3D Conversions

We have two files for the two parts and AIDs.

Here is -1 COVER detailed

Then we add a new sheet and select -2 COVER set up the sheet and detail the AID.
