A new version of CADinTools 4.0 for CorelDRAW and CorelDESIGNER was recently released. It adds an extra toolbar to CorelDRAW 11, 12, X3 and X4 as well as CorelDESIGNER 10, 12 and X4. For those creating technical illustrations, it offers a number of features not found in CorelDRAW and simplifies other tasks. Features include: scale, information between two points, transformation of shapes and nodes, drawing lines and arcs, isometric, surface development, calculations and more.
To better understand all the features, download a fully functional 15-day trial version. Or you can simply order a copy. If CADinTools offers the CAD-like features you need, it is an absolute bargain compared to the cost and learning curve of a full-fledged CAD application.
