LT Toolkit 2000 (with LISP) provides the ability to run LISP in AutoCAD LT 2000, and use thousands of existing LISP files from the Internet, or to let the user write their own. Users can increase their productivity by utilising the enhanced and extended commands provided.

A number of functions and commands have been added. The additional commands allow for easy configuration of the function and cursor control keyboard keys, which can then be used to automate common functions. For example one can control the current layer, create a new layer, freeze, thaw, lock layers by pick and so on. Other commands allow one to easily set a viewpoint and UCS using minimal key presses. These functions are all available as an API for inclusion into your own application.

The LISP enabler allows for both simple and complex LISP programs, including runtime loading of LISP files. It will also work with LISP created with 'protect', 'kelvinator', or 'loklisp'.

LT3D 2000

LT3D 2000 is a full 3D modelling plug-in for AutoCAD LT 2000. It includes routines for creating 3D surfaces and solids, and tools for modifying and editing them. In addition there are some routines to make viewing and manipulating a 3D scene much easier.

* 3D surface entities: 3D face, polyface mesh, 3D mesh, revolved surface, tabulated surface, ruled surface, edge surface.

* 3D solid entities: box, sphere, cylinder, cone, torus, wedge, extruded solid, revolved solid.

* 3D Boolean modelling operations: union, subtract, intersect, slice, section, interference.

* 3D object manipulations: 3D array, mirror 3D, rotate 3D, move z, copy z.

* Utilities: edge, explode, massprop

LT3D PRO (with LISP) is a combination of LT3D 2000 and LT Toolkit 2000 (with LISP).

Smart Architect LT 2000

Smart Architect LT is claimed to be the first add-on for AutoCAD LT specifically designed for the building and construction industries. For the first time a complex 3D object based application can work with AutoCAD LT as the main engine. Smart Architect LT uses ObjectARX technology to create virtual building models, but uses the well known AutoCAD LT user interface to ease the transition from traditional 2D to 3D based design.

This technology allows objects to be viewed in 2D for plans, while at the same time allowing third angle or perspective viewing of a complete model. drcauto has taken care to keep the user interface simple, with the use of standard AutoCAD LT commands where possible.

Smart Architect LT 2000 offers a wealth of features such as:

Smart wall technology: Numerous wall types are available, from cavity walls to timber, to concrete, and partitioning. All features such as height, width, rate, code and even linetype and layer may be altered by the user. The user can easily add wall types not catered for to the list. Straight or curved walls can be drawn with automatic intersection cleanup. Windows, doors or any openings cut into walls are automatic whether viewed in 2D or 3D. The user may elect to include hatching when drawing the walls or hatch walls after the event. Hatching will look after itself at all intersections and openings. All the standard CAD editing commands can be used on walls, eg copy, move, offset, fillet, grow, trim, join, break, etc, thus reducing the learning curve and not increasing the number of commands to be used.

Doors and windows: An extensive range of door and window styles and configurations is available. Dialogue boxes are clearly laid out and simple to use allowing for alterations to sills, thresholds, mullions, jambs, door swings, etc. Drawing a simple outline is all that is need to create a new style of door or window that is not included in the list. Each entity that makes up the door or window can be modified after insertion. There are automatic numbering routines as well as schedules and elevations.

Roof builder: Smart Architect is able to generate a roof of virtually any style and shape. The dialogue box provides a range of standard roof styles as well as the ability to generate a profiled roof. The roof can have plains added to it at a later stage, the shape can be manipulated and stretched to suit and shapes can be cut out of it. With all this flexibility, the roof does not lose its intelligence, and all quantities will automatically update with the alterations.

Elevations and sections: Sections can be cut through buildings to include all entities from 3D furniture to roofs, windows, doors and floors. Internal or external elevations can also be pealed off. All ceiling and floor RL settings will be reflected. Sections and elevations will also account for any externally referenced files that may have been used to make up the model.

Automatic layer assignment: All entities automatically default to a predefined layer. This means that a user can load the software without having to give any thought to layer configuration and can simply begin drawing. The layering convention provided in the software can be altered to match the convention of the user or the office standard. If the assigned layer for a particular entity does not exist in a drawing, it is automatically created and the entity will default to it. The system will also allow for entities to default to the current layer.

Command access: Commands can be accessed through pull down menus, tool bars and the keyboard. The keyboard comes with many pre-configured hot keys, but is completely programmable through the use of a dialogue box. The pull down menus are structured to follow a typical drawing method and along with the description of the command, provide the keyboard short cuts. The software takes advantage of the Windows environment by providing tool bars that can be modified to the preference of the user.

Database: The Database can be tied into your title block and changed or updated as the drawing progresses. The information in the database is reflected in the Drawing Manager when opening a drawing.

Project management: Extra floors can be added to a building with a single command, creating a new drawing of the next level and automatically cross referencing it back into the master file. An XREF Manager is provide for moving from drawing to drawing within a project tree. To save confusion, an external referenced file can be opened by simply selecting it with your cursor.

Drawing documentation: The laborious and repetitive tasks of labelling and dimensioning a drawing are alleviated with a drag and drop labelling system which is categorised and an automatic dimension command. A label can now be added to a list an never needs to be typed into a drawing again, with the drag and drop dialogue boxes making label placement very easy. Text fonts and heights can be adjusted at insertion time. Once a building is complete, the plans can be dimensioned with a single command.

Commercial and concrete: Although Smart Architect LT and Smart Draft have a great strength in domestic drawings and models, they also focus very strongly on commercial routines, with grid and column layouts, parking layouts and curtain walling. There are many routines and symbols to cater for commercial interiors and ceiling grid set-outs.

2D and 3D stairs: All the parameters for stairs can be adjusted to meet the specifications of the project. The dialogue boxes are self explanatory with common building terminology. The stairs can be drawn in render quality 3D, 2D and section to graphically reflect the information provided by the user.

User block library: The Smart Architect LT User Block Library provides the ability to sort all the blocks, used in a drawing office, into categories. This library can be located on a particular machine or placed on the server allowing all users access to a single location.
