Hot Door CADtools 3 is a major upgrade for Illustrator 9, 10, and CS with a full-featured set of precision drawing tools for both 2D and isometric illustration. With CADtools, you never have to leave Adobe Illustrator to create professional layouts with extreme precision and artistic control. CADobjects draw in document or layer-based scale, snapping to flat, or isometric grids. Intuitive palettes provide live control of size, styles, and placement of objects in scale. Labeling tools make document notes easy with new customization. New dimensioning tools follow isometric settings and dual dimensioning and tolerancing. Live updating allows artwork to follow CADtools styles, scale, and isometric settings. And CADtools works just like other Illustrator tools - making design work easy and elegant.
