FMX 2D drawing

[wuwuxin 27]

I would like to use FMX 2D drawing to plot an engineering diagram (with user interactions) - I need advice on where to start. 

 

Any good FMX 2D drawing demo,  book, or tutorial?

 

Thank you.

Hi wuwuxin, the 3d scene environment, you can create a 2d environment by fixing the camera angle,
I think this is the best resource you can find.

even if I were you, I would back up the videos of that channel, you may not find it tomorrow.

I don't know exactly what you need but you can catch it yourself by browsing the videos. 

Thank you to.

If you’ve done any 2d drawing with VCL it’s not too dissimilar to that. If you need interactive drawing, use a TPaintBox component and write your drawing code in the onpaint event. This control can also detect mouse actions so that you can respond to events like mousedown, mouse up and mouse move.
