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 Design, that is available in even the most Pro/e-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?
ZW3D is a sketch based system so it is easy for the major CAD system users to get up to speed fast. But it also has Primitive Shapes available that can eliminate the need to sketch and extrude in many cases.
I saw the following video challenge on linkedin and thought I would give it a try. I actually did it before I watched the video, so I did it a bit differently. This will give you an idea how different and flexible ZW3D is compared to the conventional Solidworks
SolidWorks tutorial for beginners exercise 159
While creating 3D models from drawing is the very best way to learn 3D CAD and maybe some design techniques is does not expose the designer to the design flexibility necessary in product design. ZW3D can be set up one part per file or multi-object which offers incredibly flexible top down design. Creating mating parts is a cruise. But modeling is just one aspect of a well designed productive 3D CAD system.
ZW3D is one the few 3D CAD systems that has integrated drawings, so you can do complete projects or sub-assemblies in one file.
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.
I always create the part before I watch the Solidworks Video, so as to not taint my process. Of course, there are a multitude of ways to create a model. There is no right way, just more productive ways. From what I have seen from these very complicated processes done by the Solidworks Presenters, it is not just limited by the 3D CAD system.
Here is the drawing if you would like to follow along.

I insert a cylinder and size it.
We insert the vertical cylinder locate, size it and set it to add.
We create a sketch on the XY plane.
We exit the sketch and extrude and set to add.
Now insert another cylinder at the center of top of the vertical cylinder, size and set it to add.
We insert a block, locate, size and set add.
We insert another block at the end of the existing block, we located, size and set to add.
Now we insert a cylinder on the center of the large cylinder. ZW3D recognizes centers, midpoints and corners to place features. We then size and set to remove.
We insert a cylinder at the center of the large cylinder again, locate, size and set to add.
We insert a cylinder to create the center cut at the center of the existing boss size and set to remove. The length is still in the dialog box.
Now for the bottom rib. We locate the origin at the bottom quadrant of the inside boss, locate, size and set to add.
We create the mounting tab at the lower quadrant point of the outside radius of the large cylinder. We then pattern them.
We should have put the bosses at a early step. But all we have to do is move them before of the inner cut.
We add the 4 holes by inserting cylinders, locating, sizing and set to remove.
We have four thread holes. ZW3d has a wonderful hole wizard to define threaded and other type holes.
We will put the M10 threaded hole in first. We select metric, the holes size, select thread and set the depth.
Now for the mounting tab holes. We just locate them at the center of the mounting tabs.
Two more holes. We insert a cylinder at the top locate, size and set to remove. We select the pattern feature command to create the lower hole.
Now for the fillets and we are done.
It is very important that you look into how you or your engineers are creating the parts. Streamline Sketching and Feature Based Modeling is easy to learn and implement. It, alone, will increase productivity 10X. Now, ZW3D with its add primitive shapes can increase your productivity another 5X or more with changes! Again, time is money in engineering.
