Hello, i have one question. Please, you can help me, where i find a function of "definition of distance" ? For example i make a rectangle of size 100mm x 100mm and i want give a point inside, but from left side 40mm and from down side 40mm. I really dont found a function which can make it. I like this SW, is easy, powerfull and is portable. I used a trial now, but i really think about buying this SW.
Thank you for help
