Hi
I am posting a new version of my CAD program, but I need some help
Once you have drawn a couple of entities on the screen, click on the red cross at the bottom of the screen (this will cancel any drawing commands). Next you mark some entities on the screen. This you can do as if you where drawing a box. The program will then re-color all the drawing entities black (I am working on the routine to redraw the marked entities with dashed lines). Then you select the "Rotate" function to rotate the marked entities.
This all works fine, but when you release the stylus from the screen, the drawing is not right. There is something wrong with the formula that I am using!
Can anybody help please?
Thanks
Michael
