Pros & Cons from Real Users

Pros

  • Great for making simple diagrams quickly. Free & open-source. Simple layout & easy to use. Multi-platform availability.

Cons

  • Outdated interface. Lacks features to build complex designs.

Pros & Cons from Real Users

Pros

  • Excellent cross-referencing system (contacts/coils), easy component creation, and bills of materials that save hours of work.
  • Nothing. I liked nothing about this, but I never got past trying to create a title block, so for me there is NOTHING to like.

Cons

  • The initial learning curve, as drawing measurements are based on pixels.
  • The dev's use of unusual methods to do simple tasks
