3D Modeling Techniques 
ZW3D vs Solidworks Lesson
Streamlined Sketching/Feature Based Modeling

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 and Solidworks 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.

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 and Solidworks lessons, there are some very stark differences.

SolidWorks 2018 Beginner 3d Modeling Tutorial


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?

I could do this model a bit more productive but I want to start it without too much design intent study to shows some interesting features in ZW3D. It is obvious you would start with the cup since you have to shell it. But you will see 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 are already in millimeters. So we can start modeling.

We start by sketching the handle contour.

We now create offsets of 7.5 mm

We delete the original contour and connect the ends and we are done with the sketch. Notice there are no constraints.

We exit the sketch mode and create the extrusion at 15mm.

We now need to make the center cut on the handle. We will create a sketch on the front face. We just create 5mm offsets and close the ends.

We exit the sketch mode and extrude remove the new sketch to the depth of 5mm

Now we are going to use feature based modeling by mirroring the feature.

Now to add the features on the left side. We will insert a cylinder on the top edge of the handle and size it and add to the model.

We again mirror the feature.

For the center cylinder we insert a cylinder on the top of the existing cylinder and size it.

We just insert a cylinder on the top of the existing cylinder and set to remove to ceate our hole. We are done with the handle

We insert a datum plane in the Z axis 37.5 + 27.5 to sketch our cup.

We create a sketch in the new datum plane and sketch the cup. This is an example of Streamlined Sketching. I create two reference lines and construct offsets. No constraints.

This shows all of the graphics used to create the cup. I will delete and trim the entities to get the top of the cup. The only input was for offsets and the corner fillets.

Here is the final sketch. We have to add the fillet in the sketch since the drawing shows the taper. The Solidworks presenter missed this.

We exit the sketch mode and extrude 27.5 with 10 degree draft.

We add the fillet on the bottom.

Now we have to shell the cup. Obviously we can not shell it here since it would also shell the handle. So we will have to revise the history. We could have developed the cup first but I wanted to show how to fix this.

Now we just select continue to end and unsuppress the other steps and you can see our handle sticks into the cup.

Since our handle is an extruded shape we can just edit the sketch.

We exit the sketch mode and we are done with the part.
