Good thing I just stocked up on a supply of Z80 chips.

now I start to play with QCAD software and start by reading its user guide.
so I am wondering if you have any genius way to master this software quickly?
diligent hands rule....

Other people's code is how I learn the quickest, TBH. I'll skim a manual and then look for examples of things I'm likely to want to do until I get my "sea legs"

I know it wasn't directly about mastering a software package, but my point was I learn by doing.
See if you can find a youtube video, play it back at double speed, and then just mess with the program.

No, CAD software has a steep learning curve. Some are a tad easier than others but none of them are easy.

I agree. Almost all CAD software takes a fair amount of time to learn and be useful, especially 3D. Fun, but not so much sometimes.

this QCAD is 2D drawing, a little easier.

Once you learn 3d, it saves you a bunch of time. And i do mean a bunch. If you are going to do a lot of drawing, do yourself a favor and take the plunge. Alibre CAD is $200 bucks for a full starter license, or go with Fusion or another option for cheaper.

I agree. AC3D from inivis.com is a good starter at $99

As far as I've seen, AC3D isn't a CAD package - there aren't any dimensioning tools in it to my knowledge. If you know differently, then by all means correct me, but if it doesn't do dimensioning I'd highly recommend NOT purchasing it for CAD work. It will be too frustrating. (I played with it a long time ago.) FreeCAD is a better alternative, but it isn't as user friendly as Alibre CAD, or the other options mentioned.
If you are into AC3D, Blender is another option you may be interested in. For many items it is far easier to use than AC3D, and far more powerful.

I agree.
AC3D is a cheap intro to CAD. Blender is a curious app which I have used. Rendering etc.
I use Rhino3D when I am serious. But not cheap.
There is CAD and there is rendering (ray tracing, etc.)
not always congruent.

No. It is a cheap intro to creating objects in 3D. (Blender is cheaper, at 'free'.) CAD (Computer Aided Design) is something else, and dimensioning is a central part of that 'something else.' With a proper CAD drawing (not a file, but a 2d drawing printed on paper), you can hand it to a machinist and they can make the part from scratch because it has all the dimensions and tolerances needed to make that part. AC3D is incapable of making such a drawing without tons of work to fake the dimensions. You won't be able to have those 'fake' dimensions update when the part is stretched because they will be pure objects (lines, rectangles, elipses, and even text objects probably...) made to look like real dimensions, but having no connection to the part's real attributes. Any competent CAD package, including QCAD, will have real dimensions that can be updated with the part. AC3D most definitely does not. It would be a grave disservice to point a newbie at real CAD drawing to AC3D because it is a waste of their money, for what they want to learn. FreeCAD would be better, because it introduces them to the concepts of real CAD, and it is free. But there are better options available.

I said it was a cheap intro not the only intro. Yes, Blender is also a cheap intro. QCAD is too.
Your lecture on CAD tool capabilities is note-worthy for CP audience. For me, been there, done that.

OP is doing 2D design. The only real point in doing 2D design is to get dimensions down on a scaled drawing in order to hand it to someone for production. You can't 3D print from a 2D drawing. AC3D might be usable for 3D printing, but it is not usable for 2D dimensioned drawings. So obviously, you haven't done that if you don't know the difference in those capabilities. As I've said elsewhere (too often - I should just shut up) AC3D is not the tool they need, even for beginning to learn the CAD they are trying to do. If it was just 3D printing - maybe. But if they are focused on 2D prints, that is not their goal.

Agree. Have done that.
I used one of first 3D printers available at the time. 2015?
Yikes, what a mess.
The software was to control the order of things, but users could easily break it.

"Computer-aided design (CAD) is the use of computers (or workstations) to aid in the creation, modification, analysis, or optimization of a design"
Yes, there is more to it than that. Inivis calls it a "3D design software program". So it is an intro to CAD.
Done.

From someone who has done CAD in the manner specified by the OP, Invisis AC3D is definitely NOT an introduction to that type of CAD, and will just piss the OP off when they find out what real CAD is. They will know that they wasted their money. They would be far better off to play with FreeCAD for free than to spend $90 on AC3D.

Understood. Respect that.
Done CAD of all flavors for 40+ years.
Just my opinion.
