Just a gentle reminder from our legal department about the use of
third-party applications with AutoCAD LT -
As you know, AutoCAD LT software delivers cost-effective access to full
drafting productivity. AutoCAD LT does not, however, permit add-on
applications based on ObjectARX®, LISP, or VBA.
You may have heard about or seen advertisements for applications that claim
to enable functionality such as LISP or 3D commands or that extend AutoCAD
functionality. Use of any such add-on applications or extenders is
specifically prohibited by the AutoCAD LT Software License Agreement.
Furthermore, to the extent such applications require copying of AutoCAD LT
or any portion of its code, they infringe Autodesk's copyright in the
software.
By contrast, applications that customize the user interface (CUI), provide
Diesel macros, provide Dynamic Blocks, or use other documented AutoCAD LT
features and available functionality are within the scope of the License
agreement and are an acceptable use of the product.
To protect AutoCAD LT customers from the risk of unauthorized use of AutoCAD
LT by third-party developers, and to protect its own intellectual property
rights and reputation, Autodesk will take such steps as may be necessary to
stop, prevent and/or impede such unauthorized use.
