If you are not computer savvy I recommend staying away from cracks. They usually have virus/trojan horse attached to them. If you do run cracked software, at least run it on a virtual machine. Ideally on a stand alone system.
If you don’t know what a crack is, don’t bother running it. It’s an illegal stolen copy of the software. There are enough legitimate alternatives out there that there is no good reason to bother with them for someone in your situation. If you want to do just 2D drawing in CAD (like brackets, flanges, etc) you can get Fusion360 to do that, but there’s a learning curve. The bonus with Fusion360 is that it also can take your drawing and produce the GCode (CAM software). Most free 2D drawing wont have that ability built in.
For your intended workflow you probably want to research Inkscape .
Inkscape is geared toward the more artistic drawing and text. Once you produce the drawing you need to convert that drawing to GCode, this is done with CAM software. Fusion360 is both CAD (drawing) and CAM (generate GCode). While it is good for producing technical drawings, it’s not so great for artistic stuff. So you use Inkscape for that, then import the Inkscape drawing into Fustion360 to run the CAM software on the drawing.
