I've been using Altium for work
Me too, since the Protel days way back in 1990.
I've been on the lookout for a new and not free package. Something stable I can live with for a few, preferably many, years.
I've tried a lot of them now (circuit studio, eagle, design spark, orcad, easyeda and a few other web based waste-of-times) and I think
I also went on this pilgrimage, but mine lasted from 1996 (when I became dissatisfied with Protel/Altium) until 2014 when I found DipTrace V2.4. It had some real quirks then, but lucky for both of us many of these were fixed in V2.9 & V3.
I've found my favorite!
Welcome to the club!
So close to the Altium feeling with a fraction of the cost.
For me it is soooooo much better than the Altium feeling.
Don't forget to checkout the "hotkeys". You can set many of the repetitive functions to a single keyboard key. I've made many of mine to be identical to Altium's keyboard shortcuts.
One thing I really like is that you can change between imperial & metric whilst you are editing within a pop up window. Even Altium can't manage that!
Also, make sure you join the DipTrace Forum. The design engineers read the customer posts carefully & many of the suggestions are implemented in the next update version. This is something that Altium could learn from "Listen to your customers".
