The HDAutoDRAW
DLL has been developed over the last
decade. This D LL allows software developers to create CAD
(computer aided design) drawing files with ease and speed.
Parametric drawing programs typically run from the $100,000 to
$1,000,000 price ranges. HDAutoDRAW allows you to
develop your own custom drawing programs for a fraction of the
cost and cuts development type from years to weeks. The file
format is DXF (Drawing eXchange Format). DXF
is very close to a universal format allowing you or your customers
to view the drawings created regardless of the CAD system used.
