Freecad tutorial - Product design #006 - Screwdriver (modeling _demo.)

This is the screwdriver concept. It can be used one handed, or more often with two hands. Even with the most common tools used, at least some knowledge of human anatomy is required. Handle, should be modeled having those things in mind.
With this model, it's easier, for me, to have every single part, or feature, available for adjusting. This is the major reason why the whole handle has to be modeled out of the parametric shapes. And to avoid using other methods.
Anyhow, approach to screwdriver modeling can vary, and specific approach, might be, or depends by the reason of usage.

Freecad tutorial - Product design #005 - Fork (modeling _demo.)

Fork! All mighty fork! An everyday tool...

I'm not sure if this is the best way to model the pork, but, it did the job. While i was in a process of modeling, i had too many issues in dealing with geometry and parameters. This video shows only whats working. So, it may seem it works all well, but within process, if steps doesn't follow what geometry expects, it just won't work.

To avoid this problems, there is one option for refining geometry, in a way to make resolution, or tessellation, of an object, heavier, so to speak, i think... I'll make another tutorial soon, i hope, and show exactly what i meant, and in what kind of situations this occur, as well how to solve this kind of problematic situations.

This problems will happen more often if we are modeling some sort of organic shapes.

Freecad tutorial - Product design #004 - Door|Gate Latch (modeling _demo. + animation)

This is another product which, pretty much, is  common, or known on the market. Gate, or door latch, exist in so many versions, or designs, you can't count them, function is the same, but mechanism, too, can vary from model to model.

I have already prepared many products, and modeling workflow, for uploading. Some of them will be covered with guides, some are without, but it will be useful to many. Many tutorials helped me just by looking at the process of making it...

For situations, which are too complicated to understand by watching only, i'll upload them separetly, with guides.

Even within the simplest designs, like this one is (more-less), in designing or modeling process, problems are normal. We can solve them, by using tools available. And there are milion ways we can use them. We just seek for the cleanest solutions. Solving those problems, requires practice. Our approach is done by our logic, and, for that we must be familiar with the tools we are using...

Blender tutorial - Infinite plane | Shadow catcher | Cycles

I have already done infinite plane tutorials, (tut1, tut2), but, it is, more/less, outdated. This one i did, kind of, in a hury, i needed a quick solution, without too much tweaking within different properties, or nodes, and so on...
Previously i had, in compare to this one, a ton of nodes, but, doesn't have to be that complicated, except, if situation requires otherwise.
If transparent shadow is required, this is, again, solution for it, as it is shown at the end of this tutorial. So, object, or, product, can be saved along with the shadow, and, doesn't have to be separated layer. There are options, of course, to keep shadow as a separate file, if it's needed.

I hope this tutorial, or, as just a tip, can be useful to anyone.

Cheers!

Freecad tutorial - Product design #003 - Bottle (Modleing _demo.)

A bottle, maybe one of the most covered subjects in designing. As i remember, from the time getting into industrial design, there was the whole one period of bottle studying, for students, and for teachers, or professors. Students did have problems with the bottles, and teachers with the student bottles, they were not always the good ones.
But then comes 3d modeling, how to start the "thing" already, just ain't gonna start by watching. I had a fun time, that's for sure.

Now, with this video, i wanted to show the way on how to model comlex shapes by using primitives, or a bit more complex primitives.
It's all in a logical order, by adding or subtracting parts of a material.
If, from a designed model, we can recognize more objects, like those primitives are, than the model will be made of more simple parts in one combined object.

Technic requires practicing, but in the end, it gives us ability to create complex organic shapes, if design requires it.

Freecad tutorial - Product design #002 - Rotary switch knob (modeling _demo.)

This is another demonstration of a product design i did, in a video is the rotary switch knob concept only.

For this specific model, i had a problem in ribs modeling. Ribs that were made straight, so to speak, by 90° degrees angle, are easy to make, but, in this situation, where ribs have to follow an angle, i had to think for a while. So, i made one solution shown in a video.

I wanted to make this video shorter, but, i decided to upload the full lenght, and i'll problably record tutorial for any specific problem in a far shorter video, or videos.

Freecad tutorial - Product design #001 - Handle (modeling _demo.)

This is only demonstration of a workflow i used in modeling this handle design.
This is not learning tutorial, but if anyone can learn even some small tip, i'll be glad. If there's a need for specific tutorial, i'll cover them in a very near future.

This is a simple design, but, i had a lot of problems while i was making it in the Freecad. Once the problems are known, it can be done without any minor problems, or, crashing, freezing and so on.

Problem was to achieve an organic shape. The least painful way was to use simple forms, and combine them in one unique shape, and, no usage of splines, or, surfaces. This way, i had a lot more control over every segment of a model.
There's a ton, so to speak, of a designs a'm going to upload, all of them had a specific issue in making process.

Freecad tutorial - part 01_11 - Getting started | Alignment | Assembly #003

The file used in tutorial can be downloaded at the following link:
http://goo.gl/jsFdpc

This tutorial certainly doesn't cover all there is, that is related to the Draft Move tool, but, covers basic usage in general. In the following tutorials i'll try to go through other related tools and features, which may explain more clearly how does this tool works. Anyone, of course, can take some time and experiment with the tool, which is can be quite efficient in learning.

To get complete sense of this tool, it's good advice to get familiar with the Draft workbench. As soon we get familiar with the environment, sooner we're going to learn other tools, as well, predict certain procedures and steps, thus, the end result, or possible errors to occur.

Another thing to mention is workflow. While we are at working process, it's very useful to know shortcuts. This technic can give us very fast workflow, once we get used to it.
