Hi, I am a beginner in 3d world. I play with the soft. I made a stupid thing for just fun. Now I must do functional things but I don't know how to be sure that will work. The bartop will make with a CNC and I don't know when it is possible to make it with the machine. How you know when your model its work?
Everyone here is not speaking English as a first language. Expand your mind a bit..... No offence intended....
First, you must know how the CNC machine work. The product that you make must not have an undercut surface.
You can check your product in Solidworks using "Draft analysis" or "Undercut analysis" on "Evaluate" command manager.
The first thing to do would be to upload the part file to your GrabCad profile, a solid works part and an exported step file would be the best. The we could give you some advice on how to use this to generate the right sort of CNC for the best process to turn it into a real object
Hello,
I'm agree with Lawrie, the best thing will be share one file, and i will be happy to help you.
Best regards

for rappel, it's not finished. I search just how to make a good 3d model. ( and sorry for my English I am 16 years french person. )
So I try again (and right English is not my native language). I make a bartop ( a little arcade cabinet). I don't know how to verify my file can be made with a cnc.
What material are you going to use to make the cabinet? If it is the geometric shape shown in your link, any machine tool can process it. In my opinion, your cabinet should be made of boards and does not require CNC equipment at all.
I hope I understood correctly, after all, I am not from a native English country
Basics rules for designing and building anything.
So far there has not been any 3D modeling required and none is required for you to make your project. You could use the old way of making things, get out a piece of paper, work out the required dimensions, make a few hand drawn sketches and build it. If we have 3D CAD available we could make use of this tool, as when you know how to use this tool the documentation part a project can be way more efficient than the old pencil and paper approach. Also further gains can be made when we take this CAD data and make use of it to produce nc files to produce these parts on CNC machines.
CAD and computers are just tools that we use in the design and manufacture process. When I started out in this occupation they were not available to most of us, we used slide rules, log tables, pencils and paper, it took longer but if you had the knowledge we got things designed and built. They built the Eiffel tower without CAD, it looks great and has not fallen down.
Looking at the model you have so far, it is nowhere near what you need to actually make this bartop. Put this to the side, get a pencil and paper then work out and sketch the bartop you have in your mind, work out the parts required, how they fit together and how you can actually make the real world parts. This is the point you introduce the computer and CAD into the process. Model each part exactly as the real world part will be. Once you have a good accurate model of the bartop, we now can make use of the advantages or CAD model has over the old pencil and paper option, we can give it real world properties, look at it from all angles and use the parts to assist in the CNC manufacture process. The design came from our mind, CAD was just a tool that only works if we have in our mind first what we wish to make.
It is very helpful. I have a sketch on paper to give me an idea. But if I understand your advice, I must continue it to have a better idea of each part?
Yes it is most important to have in your mind how your project goes together. How each part fits with the whole assembly. How each part will be made. Your CAD model should be a digital copy of the intended real word object. The computer does not think, you need to be able to tell the software exactly what you want. https://grabcad.com/library/side-table-41 This is a simple side table that will be constructed from recycled plywood in a local community center wood workshop that I am involved with the running of. The design is based around someone wanting to make this, the recycled wood we have available, the tools and equipment available and the skill of the person who wants to make it. A look at available material, and a bit of thinking how and what. Once the plan is in your head the CAD model is the simplest part. You need to know the exact specification of what you want to be able to make a useful CAD model.
If you wanted to make 1,000's of tables such as my simple example, it would be a simple task to use CNC mchines to make the parts required. The standard kitchen cabinets we can purchase from hardware stores are made this way. Many of the projects I was involved with the design and manufacture of include producing the nc files to run the machines. In the smaller companies you always perform more than one task. An understanding of how these machines work and how to run then helps in producing good programs.
