IMSI Double CAD XT Pro 1.0  Want to get more powerful architectural drafting & detailing capability (as in fully associative, 2D views and hatched sections, even from xrefs) Or more sophisticated features, tools, and file filters for mechanical design
DoubleCAD™ XT Pro is the powerful upgrade to DoubleCAD ™ XT. It’s an AutoCAD LT® work-alike. But better. For about half the price.

DoubleCAD™ XT Pro is a great companion to AutoCAD® and an excellent drafting complement to popular mechanical design package such as SolidWorks®, ProENGINEER®, and Solid Edge®.

With so many new, innovative features, you’ll think DoubleCAD™ XT Pro is the upgrade for AutoCAD® LT, too.
