Overview of LT-Extender 2000 Plus

Complete documentation (as both CHM and PDF) can be found in the download area.

With LT-Extender 2000 Plus for AutoCAD LT version 2000 (and higher) you are using the most outstanding, innovative software that opens a new horizon in customizing AutoCAD LT - uniquely in the world ! Combining several powerful technologies, LT-Extender 2000 Plus offers to extend AutoCAD LT with many features like Commands, SystemVariables, Lisp- and ARX-Applications, and much more.

LT-Extender 2000 Plus works with all language versions of AutoCAD LT.

Extend your AutoCAD LT with major features as known from AutoCAD !

LT-Extender 2000 Plus extends your AutoCAD LT by implementing the following features:

Features  
Providing missing AutoCAD commands provides more than 75 (up to 90) additional commands, that are usually not available with AutoCAD LT (Raster/Image-, ACIS-, 3D drawing, 3D-Surface , 3D-Orbit-, and other commands)...  see commands list
ARX-Interface allows you to load & run ADS/ARX-applications like they are used under AutoCAD
Lisp-Interface allows you to load & run AutoLisp-Programs like they are used under AutoCAD, AutoLisp is available at the command prompt and also within menus
TrueColor Support for LT 2004 and higher LT-Extender provides the full color selection dialog incl. TrueColor support - beside RGB and HLS,  LT-Extender also offers the CMYK color model; supports custom color books
Gradient-Hatch for LT 2004 and higher LT-Extender also adds the "Gradient-Hatch" page to normal AutoCAD Hatch dialog to create Gradient Hatches; similar, the HatchEdit dialog has been extended to support GradientHatch editing
Providing missing system variables provides about 75 missing system variables, 35 are directly accessable with the menu.
'Appload' command Appload allows you to load & run ADS/ARX- and Lisp-Applications
Interactive AutoLisp-Prompt Lisp

offers a new command prompt that features (like AutoCAD) to enter and evaluate AutoLisp expressions

automatically Load of Applications loads Arx/Lisp-Applications automatically as defined by the user; these applications are directly loaded at AutoCAD LT startup
automatically Load of Acad.rx file this support file is managed under AutoCAD LT in compatible way as under AutoCAD to ensure highest compatibility for applications
automatically Load of Acad*.lsp files these support files are managed under AutoCAD LT in compatible way as under AutoCAD to ensure highest compatibility for applications
automatically Load of Menulisp files automatically loads all those Menu-Lisp (*.mnl) files related to active menus to ensure highest compatibility for applications
DemandLoad for Arx Applications the so-called 'DemandLoad' technology for Arx applications is completely and compatible emulated by LT-Extender under AutoCAD LT
AutoCAD-compatible environment LT-Extender emulates a most compatible AutoCAD environment to ensure highest compatibility for applications by providing all important AutoCAD support files even under AutoCAD LT
ExpressTools Support allows the usage of Autodesk ExpressTools Vol. 1-8 / Vol.1-9 even under AutoCAD LT
LayerTools integrated the LayerTools offer highly effective methods to control the drawing layers with reference entities – incl. Restoring and reverse selection
AccuRender  Support LT-Extender recognises installed AccuRender software and ensures proper working by correct pre-loading some basic AccuRender Dll files

After installing LT-Extender 2000 Plus, a new menu "LT-Extender" is automatically shown, providing access to all new features, commands, Online help, License dialog, and LT-Extender's homepage.
Additionally, there is a separate toolbar available for each submenu - these toolbars are nearly identically to those toolbars known from 'big' AutoCAD.

With its easy installation and problem-free intgration into AutoCAD LT, even unexperienced users will be able to use all the new features and possibility provided by LT-Extender 2000 Plus.

Users will take profits of LT-Extender 2000 Plus in several way:

  • all important, but missing AutoCAD commands, which are normaly missing with AutoCAD LT, are provided by LT-Extender
  • Arx-/Lisp applications may be loaded and run: therefore, users can run "Third-Party"-applications (designed for AutoCAD) even with LT
  • the feature to automatically load Arx-/Lisp applications allows to have commonly used applications loaded with LT startup
  • 'LayerTools' integrated : offers effective and elegant LayerControl using reference entities
  • Drawings created in AutoCAD can be opened and edited in LT now, without "Proxies" being displayed (important for Plotting those drawings !)

Overview of re-activated commands:

Command groups  
Drawing commands 3dface, Edge, 3dmesh, Tabsurf, Edgesurf, RevSurf, Rulesurf, Sphere, Pface, Sketch, Trace, Mline, MlStyle (MlEdit under development)
Block/Atrribute commands BAttMan, eAttEdit, AttRedef, AttSync (eAttExt under development)
3D-Surfaces Box, Wedge, Pyramid, Cone, Sphere, Dome, Dish, Torus
3D Operations 3dArray, Rotate3d, Mirror3d, Align
Raster/Image commands ImageAttach, ImageClip, ImageQuality, ImageAdjust, Transparency, Advanced Image Clip
ACIS commands Cylinder, Torus, Box, Cone, Extrusion, Interfere, Union, SolidEdit, Rotation, Section, Slice, AcisIn, AcisOut, StlOut, _Union, _Subtract and _Intersect commands accept Solids; (SolDraw, SolView, SOlProf under development)
Pan/Zoom/3D commands Lense, 3dOrbitView, 3dOrbit, 3dcOrbit, 3dZoom, 3dZoomTransparent, 3dPan, 3dPanTransparent, 3dclip, 3dSwivel, 3dRender, 3dDistance, Camera
Shading commands offers the permanent shading for viewports using all 6 Shading modes:
2D Wireframe, 3D Wireframe, Flat, Gouraud, Flat+Edges, Gouraud+Edges
Reference Edit commands RefEdit, RefSet, RefClose
Common commands LayerP, LayerPMode, XOpen, XClip, VPClip, Load, Shell, Compile, Hatch2Solid, Solid2Hatch
Special commands 'Appload' (loads ARX/LISP programs); 'Lisp' opens the interactive Lisp prompt;
3DConfig offers configuration of AutoCAD LT Graphic-Interface/Driver

Some tips for the  <appload> command:

With the LT Extender the appload command is available, users can load and execute additional ARX/Lisp programms. Even under LT these programs are executed similar to AutoCAD by using the ARX/Lisp interface of AutoCAD LT. Normally about 80 % of all ARX/Lisp applications will work properly. Following restrictions for the appload command are known:

  • ARX: ARX programs might use the incorrect registry keys (of original AutoCAD), or they detect the wrong AutoCAD version or similar - then those programs might run incorrect or they will fail at all
  • FAS/VLX - VisualLISP programs cannot be used (but VL functions can be used inside Lisp. using FAS/VLX is under development at the moment)

Some common notes:
Of course we cannot guarantee that all ARX/Lisp applications work properly with LT  - but a major part will do. If you recognize some errors, please get in contact with us- maybe your report will help to improve the ARX/Lisp integration with LT-Extender.

Some notes on LT-Extender's Trial version:

  • After LT-Extender is installed, the trial mode is active and you can use LT-Extender with all features for 200 AutoCAD LT sessions. The trial version may be registered any time later.
