Hi Marky,
I have just had a quick look.

If it looks right it probably is.

There is a thing called Lynda.com that my ex-work uses as a training tool it has instructions on how to use hundreds of different programmes ,don't know if you have to pay or not .

I don't know what the easiest way to learn CAD skills is, but I suspect that they will be a common requirement for modelling before long.

I suspect that most kids - certainly those who are interested in modelling - will be learning the basics at school. But those of us longer in the tooth will have to do things on our own - much like the early days of R/C aircraft, when getting the thing into the air was a success on its own...

I found that an easy introduction into 3-d modelling was using a 2-d drawing package. Even something as simple as Paint will introduce people to the idea of having a drawing area, then using the mouse with various 'tools' to create line drawings - but I suspect that there is a better free 2-d drawing package available somewhere.

3-d drawing skills can then be added. Basically, these involve taking an enclosed 2-d shape and giving it 'thickness' - so a circle can be 'pulled up' to become a cylinder. This then becomes a 3-d object, can be rotated about its axes, and fitted to another object. Making several of these objects, modifying them and joining them together will create a complete drawing. Again, there are free downloads of 3-d drawing packages available, and it's probably worth learning on these before spending a lot of money on a professional product.

The above might be a path that someone with no experience might find useful to follow...?

All this is very nostalgic, takes me back a million ago when I was learning AutoCad as a mature student. A wonderfull learning experience.😀

This time we will look at the various ways we can manipulate edges. The pictures will hopefully speak for themselves but if anything is unclear feel free to ask questions...

Thanks Nick,
As soon as I get the chance I will follow along.

The basic principles are quite simple really, Everything is worked out on a co ordinate system, you could say fancy map reading or navigation. A map is divided into squares, each square being part of a numbered grid, same on a nautical chart. so to get from A to B, you navigate accross the chart, so point A may be square 21/06, 21 squares along and 6 up. Point B is say 18/32 so 18 along and 32 up. (asleep yet?) to get from A to B you will plot a route through the grid from one reference to another. Similarly, our CNC router, laser cutter 3Dprinter plotter etc works on the same principle, we have 3 axes, X Y and Z X being left to right, Y back and forth and Z up and down. Cad software converts a drawing, or draws as a set of co ordinates, so for a 2 dimensional square, the co ordinates could be, say, X0 Yo, bottom left corner, and X10 Y10 the top right. X5 Y5 would be the center of the square. To add a 3rd dimension, the Z axis gets involved, so on a 3D print, the first layer would be z 0.15, second Z 0,3 etc. I am using Designspark Mechanical to illustrate, the photos are, hopefully self explanatory... Next time will prepare the object for 3D printing.
