ZW3D vs Fusion 360 Lesson 13
3D Modeling Techniques Defined

Streamlined Sketching/Feature Based Modeling

I am not sure if it is due to these exercises but I have replaced a few Fusion 360 with ZW3D. Listen to what one of the fellows said.

"We spoke a year and a half or so ago about ZW3D. I took the Autodesk Fusion 360 but am becoming increasingly unhappy with it… It’s not very productive for me, just too slow and cumbersome to get things done quickly. On on the strength of your recommendations I am ready to give ZW3D Standard a shot, probably as a rental for the first year.

Bottom line is, Fusion 360 is “free” but not really free… I am finding that the slow, clumsy pace of design with it is counterproductive… time is money."

Thanks much, Brian

Again I follow up my IronCAD lesson with a ZW3D lesson. This is a bit different and quite simple. ZW3D has Boolean primitive shapes you can use, nothing like IronCAD but offers an added flexibility.

I saw the following video challenges on LinkedIn and thought I would give them a try on IronCAD. I got a great response and decided to do it in ZW3D. I was very familiar with the parts and did it a bit easier. It shows more the difference in the level of the 3D CAD experience than the CAD system itself. You can Download ZW3D and give it a try.

Fusion 360 Challenge of the Month: SEPTEMBER 2017

Here is the drawing.

ZW3D vs Fusion 360

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 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?

These have actually turned these 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 Fusion 360 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? Of course, this take a good understanding of descriptive geometry.

We are already in millimeter so let's get started.

We will insert a primitive block and size it. Nope, we do not start with a sketch.

We now will create our first reference line that are the basis of our top cut. Notice we create the line in 3D space not requiring a sketch. ZW3D has fully functional 3D Sketching. This is one of the requirements for a hybrid modeling system.

Now for the second

Now we create the plane with three points.

We just drop a primitive block on the plane, size it and set it to subtract.

We select the face for our new sketching plane and to create our lines.

I have never seen anything detailed quite this way.

Go back to the video and watch how the Fusion 360 fellow creates these lines. I wonder if Fusion 360 even has a line offset. He arbitrarily creates a line and then constrains it parallel then locates it. He does it 4 separate times!

Now we create our rectangle just by offsetting lines from existing graphics.

We trim the lines and we are done with the sketch.

We now have to create a plane to create the boss. You can see we locate the plane at the relative corner, doing this eliminates the need to find the height of the boss.

I could have done this by going to the sketch and tracing the lines, but I thought I would show you how to project entities to the current plane. I just select the ISO view and select the lines. Very easy!

We exit the sketch and create our extrusion. Arbitrarily setting the bottom and set the top to 15mm. We are done with the boss.

Now for the cut on the bottom, we just insert a primitive block on the related face, size it and set it to remove.

Blank the reference planes and lines and we are done with the part in one tenth the time. But ZW3D is  a much better system by just having the easy to use primitive shapes available increases productivity 30%. Go ahead download ZW3D, if you are using a Solidworks Clone it is easy to get up and running.

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 unique history and robust direct edit functionality can increase your productivity another 5X or more with changes! Again, time is money in engineering.

To experience this increased level of productivity, please download ZW3D for a 30 day evaluation. Legacy data is no problem, ZW3D can read the native files of all of the popular programs including the PMI data of NX, Solidworks, Catia and Creo. ZW3D is a great replacement for the subscription only Autodesk and PTC products.
