A story about how I thought I could design a machine there by myself because 3D CAD drastically reduces design errors.

Today, we are going to discuss the "A story about how I thought I could design a machine there by myself because 3D CAD drastically reduces design errors.".

The title is long again today.

Since the other day, I have been doing design work with 2DCAD for the first time in a long time,After working with 2DCAD, I realized once again how great 3DCAD is.I will make a note of the points that I feel I will work with 3D CAD as much as possible from now on. 

3D CAD drastically reduces design errors.

There are many advantages of 3D CAD, but in general

• Various good because the shape is easy to grasp.
• Seems like it would be easy to make things at one go.

and others are appreciated, but what I want to talk about today is3DCAD overwhelmingly reduces design errors compared to 2DCAD.　It's a story. Let me just make two points here.

The first is a drastic reduction in drafting errors and the second is a drastic reduction in errors when handling information.

Advantage 1: 3DCAD dramatically reduces drafting errors. The most powerful if you master how to express yourself.

It's been a while since I started working with 2DCAD, and I noticed that2DCAD had to draft each and every surface, the reality of ・・・・。　It was quite a shock to me, as I had completely gotten into the 3D CAD brain.

With 3DCAD, you create a model and proceed with the design using that model, but there is an overwhelming need for drafting and drawing.The advantage is that the model can be created in any shape and on any surface.Normally in 2DCAD, when creating front, plane, and side views, it is necessary to collect parts from inside the assembly drawing, align the standards, and lay them out.

Of course, some of the lines are partially dashed or cut off to represent assembly diagrams, so these also need to be corrected.With 3DCAD, you can bring a single model and create it in a jiffy, so the first thing you need to do isThe picture is never out of place.It is.

Reference:A story about how he thought he could design a machine there by himself because 3DCAD drastically reduces design errors [Video 1].

The expression of dashed lines can also be eliminated in a batch, or only one line can be hidden even in a batch...very fast.　Another thing that impresses me for the first time since I started working with 3D CAD is the drawing of oblique views.Inevitably, when it comes to complex shapes, the degree of grasping is completely different with and without a picture from an oblique view.These things can sometimes clear up misunderstandings of the drawings, so overall, inquiries are decreasing.

Advantage 2: 3DCAD also drastically reduces information handling errors. Property management is the most powerful.

3DCAD can store its contents in parts.This allows the information to be incorporated early in the design process, when creating the part model, or when downloading a purchased item, and it will remain with you until the end of the process unless you delete it.

For example, when you model a part to be manufactured, you can pick up all the information such as what it is for, material, heat treatment, surface treatment, remarks, etc. when you create a bill of materials for the assembly drawing at the end. It only takes a moment.

Reference:A story about how he thought he could design a machine there by himself because 3DCAD drastically reduces design errors [Video 2].

The reference video is a bit messy,When it comes to the bill of materials for an assembly, you can have the count done automatically.Of course, there is also a setting of "do not count (exclude from bill of materials)," so you can further optimize this property design by customizing it to the original company to which you belong.

Further,If modifications occur or additional parts are added to the assembly, the BOM will reflect them.When I first started using 3D CAD, I didn't want it to be easy to change, but once I got used to it, this feature was by far the easiest. Once you get used to it, this feature is by far the easiest to use.

 In contrast, (many) 2DCADs do not store the model, number, manufacturer, etc. in the downloaded data.　This is due to the fact thatThe potential for errors in manual input, such as bill of materials creation and piece counting at the end of the design phase, is very large.　It is.　In addition, when we ask someone else to continue working on a product during the design process, it is difficult to identify the model type from the outline drawing in the drawing alone, so we need to write down catalog information and supplementary information and hand it over.

This is a big difference. 

Advantage 3: The ability to notify you of changed areas.

This is mentioned in another article, "", but the SolidWorks I work with has a feature that basically changes the dimensions of the drawing when the model is changed, and it tells you the changed dimensions by changing the color. 

Reference:Settings that allow you to change the color of a dimension in SolidWorks when that dimension changes.

Functions like thisFeatures that reduce design errors　It is.

Finally.

After several years of making full use of 3D CAD, I felt again,I understand that these functions of 3DCAD allow a single person to do a good job with the equipment.　The first was to obtain a

When I was designing equipment with 2DCAD, I was not able to relax until the very end of the design process, and it was difficult to work on multiple jobs at the same time. However, after I became able to handle 3D CAD to a certain extent, I started to incorporate information into parts and assemblies, and I was able to do these tasks at the same time.　They have drastically reduced the risk at the end of the design phase.

Of course, there are still mistakes outside of this section...I would be happy to accept work in 2DCAD, but I would like to propose to work in 3DCAD as much as possible.

That's it.
