An Introduction to AutoCAD Software Since it was first released, AutoCAD has been at the forefront of the CAD (computer-aided design) industry, with new features added with each update. Since then, the software has become the industry-standard design tool used by millions of professionals. Two main variants of the software are available: AutoCAD and AutoCAD LT. These contain the same core features, but AutoCAD supports both 2D and 3D drafting and has greater automation functionality, while AutoCAD LT focuses on 2D drafting, with limited 3D capabilities. This guide provides a comprehensive comparison of both products, outlining their features, functionalities, and pricing structures. With this information, you will be able to make an informed decision about which software aligns best with your projects, taking into account the project complexity, needs for 2D drafting or 3D modeling, collaboration demands, and other factors. Understanding Your CAD Design Needs To help you decide whether AutoCAD vs. AutoCAD LT can best support your business, take a moment to assess your project requirements. When comparing your software options, consider the constraints of your budget and whether a long-term investment in the more expansive features of AutoCAD would enhance productivity and reduce overall costs. 2D drafting vs. 3D modeling. The purpose of a CAD drawing is to convey information. While 3D CAD can be more enticing, this may not always be the best way to present your concept to others. For example, an electrician may only need 2D drawings in order to wire an assembly. Similarly, if only a single drawing from a single angle is needed, a 2D isometric drawing may suffice. For more complex situations, such as needing to view the design from multiple angles, 3D modeling will provide greater flexibility and improved productivity. Complexity of designs. The overall scope and level of detail can also impact whether 2D drafting or 3D modeling is the best choice for your project. 2D drafting generally works well for simple design projects, such as those with geometrically simple representations, standard colors, and basic design modifications. As the complexity of the project increases, 3D modeling may prove to be more suitable, even with its higher initial investment. This complexity may include needing to show a greater degree of depth and perspective or viewing the project from multiple angles. Collaboration needs. It is important to understand how you will be collaborating with others during the design process because this can impact which CAD software will support your needs. Some questions to consider include: Are team members in one location or at different sites, possibly in multiple countries? Will multiple users simultaneously be editing the same CAD file? What level of access control is needed during the project, such as limiting who can modify, view, or add comments/annotations to the designs? Will completed designs be shared with manufacturers, vendors, or other stakeholders? What software and CAD capabilities do various stakeholders have access to? Customization requirements. When thinking about which software will meet your needs, consider whether the core software functionality is sufficient, or if you will need to customize and extend that functionality through the use of APIs, plugins, and add-ons. AutoCAD has several different environments to help you customize and extend the software functionality. AutoCAD LT has limited customization and automation capabilities. Industry-specific toolsets. AutoCAD offers access to seven industry-specific toolsets for architecture, electrical, mechanical design, and more. These can enhance productivity by providing a range of capabilities tailored to your role and industry. These toolsets are not available in AutoCAD LT. Unleashing Design Power AutoCAD is a comprehensive 2D and 3D design, drafting, and documentation software that is trusted by architects, designers, engineers, project managers, real estate developers, and construction professionals. The software supports the design and annotation of 2D geometry, as well as 3D modeling with solids, surfaces, and mesh objects. The 3D modeling tools included in AutoCAD can also be used for easy manipulation of 2D objects. This software enhances your 2D and 3D design experience by giving you precision tools to automate drafting tasks such as placing objects with AI, comparing drawings, creating schedules, and publishing layouts. It also includes features such as parametric constraints, dynamic blocks, sheet set manager, and more. Advanced customization options in AutoCAD are available through customized workspaces, APIs, AutoLISP, and apps. The AI-generated support and solutions available with AutoCAD enables you to troubleshoot design challenges and ask questions about AutoCAD features without leaving the workspace. AutoCAD also includes specialized toolsets designed to increase productivity with enhanced features and intelligent objects. These include the Architecture toolset, Mechanical toolset, Map 3D toolset, MEP toolset, Electrical toolset, Plant 3D toolset, and Raster Design toolset. AutoCAD also includes CAD standards functionality, which provides an efficient method of checking standards. To help you stay connected with your team, the software allows you to share AutoCAD 2D and 3D DWG files across desktop, web, and mobile platforms. This enables you to work the way you want, and capture, share, and review ideas from wherever you are. You can also manage design data across projects using Autodesk Docs, the cloud-based document management and common data environment that is part of the AEC Collection. AutoCAD can be used for a wide variety of design and drafting projects, but excels at helping you design solutions that meet clients’ unique challenges. With precise drawing, advanced graphic capabilities, and a large database of templates, AutoCAD enables architects to create complex, yet efficient, architectural designs. The software provides greater control over the designs and allows you to quickly create realistic 3D models that can be explored from different angles. Robust drafting and modeling tools included in AutoCAD facilitate the creation of intricate mechanical designs. Using the software, 2D sketches can be transformed into 3D solids, simple 3D shapes can be used to create more complex ones, multiple 3D components can be combined to create assemblies, and other features. AutoCAD also supports ambitious landscape design and infrastructure projects, including tackling regenerative designs that have a positive impact on natural and human systems. The software can even be used to design infrastructure projects such as trail bridges that take into account local topographic and geographic conditions, and logistical challenges. AutoCAD LT: Streamlined and Cost-Effective 2D Drafting AutoCAD LT is a cost-effective 2D drafting solution that architects, engineers, construction professionals, and designers can use to design, draft, and document with precise 2D geometry. This lower-cost solution is primarily suitable for users working on 2D projects with a limited budget. The software has limited 3D viewing capabilities and does not offer the 3D modeling and customization options that are offered in AutoCAD. However, with AutoCAD LT, you can create a 2D isometric view of a project using the same constraints as a 3D isometric view, although this isometric design can’t be manipulated as easily as in AutoCAD. In addition, checking CAD standards in AutoCAD LT largely requires manual input, which can be time-consuming and may lead to errors. However, AutoLISP routines can be created—in both AutoCAD LT and AutoCAD—to automate these tasks and reduce the time needed to complete the task. AutoCAD LT does offer collaborative tools for sharing and annotating drawings across desktop, web, and mobile platforms. The streamlined interface of AutoCAD LT is also intuitive and customizable, which is ideal for creating quick design iterations, and the software supports workflow automation using AutoLISP.

Glad it can of use!

Too late

have nice weekend ps updated the code a little bit (create empty data file on first use) , reset environment (cleared registry / data files) but no error... usually the error you describe has to do with nth function. But I'll do some more testing to try to reproduce the error. upd. 2025-09-06 : addressed some first use issues , code above updated.

Cheers, I have broken my rules... weekend and CAD is off... and now it is weekend and beer time.... CAD is still on.... No, that didn't work - I'll have a look tomorrow or Monday to see if it is my machine doing something odd. Dragon is brilliant, thanks!

found the dragon somewhere on line but not sure where anymore , but I know its way above my drafting skills haha. The error is probably the default name for the dat file , on a new system it doesn't exist yet so it has to be created , but think I forgot to put that in yet , wil check it out and update the code. Creating a file c:\\temp\\GrM-Rlx.dat might fix the error for now (that is , if that caused the error) Draak3d.dwg

Thanks... looking good though... (oh, you do know that one day I will ask for the dragon - very cool)

yes the list is just a plain text file. Seems there still is a gremlin in the app , have to hunt it down... think starting setup dialog while toolbar is active is the culprit, probably better to have tootlbar and setup separate. I will have a look at this.

All working. I assume the DAT file is just a list of LISPs, I am getting 'Bad argument value: non-negative: -1' ?

Added a few options since the first version for those who like to pimp things. Same restrictons as b4 , text display is very basic , keep them short or use wider buttons , background fill is fine for standard drawings sizes , but very large units can take some time so added option in setup dialog to tweak fill percentage. Very small drawings / zoom factor also impacts fill. But then if I have to live with these limits of lisp , so do you. Very satisfying I can tell you. App can be started with c:GrM (Graphic Menu) , you probably want to fill the app list with your favorite lisp routines and app still works by loading 'MyLisp' and then assumes it starts with (c:MyLisp). Haven't tested it on a virgin system yet so hope it runs on first use. App should display toolbar with default settings and enters a grread loop , there you can select button or press S for setup , O to change orientation (left / right / top / center / bottom) and also do some zooming, oh just read the freaking command prompt. One button(key) isn't listed , D , that was for debugging. Just left it there for those who get off pressing buttons. In setup dialog top left will show if debug mode is active. You probably use it once in you life but it could be a nice template for future apps. You also can directly go to setup dialog with (C:GrMS) Well I could go on but what be the fun in that. If I did my work app should explain itself. My reason for making this is that for every job I do I make my tools on the fly and having to edit / recompile my autocad toolbar every freaking time started to irritate me and now I just pimp my own toolbar / app-list (you can save multiple toolbar data files in the app-list dialog) Well , as you should know by now : hope you have fun or else bite me (or your mother in law) Oh , if you choose center orientation I would advise to use the fixed width / height optiom ... or not , I'm not your mommie, daddy maybe... 2025-09-07 : updated a couple of first use issues GrM.lsp

YES !

could you type or speak a little louder because I can't hear you Steven

just google voicecontrol autocad and you get things like voice2cad

Look at SAPI (Microsoft Speech Application Programming Interface) https://learn.microsoft.com/en-us/previous-versions/windows/desktop/ms720151(v=vs.85) I goofed with Python’s SpeechRecognition library, but I didn’t want to spend the time to sign up for a proper service, i.e. Google’s API, the results were pretty bad. Best approach would be to use a language with support for multi-threading, that way you could have a background thread listing for commands

Hello everyone I'd like to know if it's possible to execute AutoCAD commands using voice recognition. Is this possible using Lisp? Thanks in advance

I know that's how command line works (typing in points), but you have to pass it a list. so either use getpoint or use the following to hard code x y z. (setq pt2 '(0.5 1.0 0.0)) or (setq pt2 (list 0.5 1.0 0.0)) Asks user to set points with getpoint. used the first point so you can see the fence. defaults do your point if nothing is picked. (setq pt1 (getpoint "\nPick Point<0.5, 1.0, 0.0>: ")) (if (= pt1 "")(setq pt1 '(0.5 1.0 0.0))) (setq pt2 (getpoint pt1 "\nPick Point<0.5, 1.0, 0.0>: ")) (if (= pt2 "")(setq pt2 '(3.0 1.0 0.0))) ; '(makes it a list -edit using @BlackBox Command-s means it wont run the command unless both points are defined. good for error handling

(defun c:FOO (/ pt1 pt2) (if (and (setq pt1 (getpoint "\nSpecify first point: ")) (setq pt2 (getpoint pt1 "\nSpecify second point: ")) ) (command-s "._trim" "_o" "_s" "" "_f" pt1 pt2 "" "") ) (princ) )

Here is what I am trying to do. Draw a TRIM - FENCE from these two points to cut the vertical lines Here is my code (setq pt1 "0.5,1.0,0.0") (setq pt2 "3.0,1.0,0.0") (command "trim" "fence" pt1 pt2) If I execute this code, I get this (the lines are not trimmed) If I manually type TRIM - FENCE - !PT1 - !PT2 I get this (it works, I have to press enter to finish) What am I missing in getting this code/command to work the way I want?

It was more of a qualifier... While I'm sure they exist, I've never personally met anyone who used Python and couldn't compile .NET Haha

FYI, it’s not .NET, it’s Python, so no compiling required https://github.com/CEXT-Dan/PyRx Though .NET certainly would work, the function is AcGeCurve3d::project Maybe similar to PROJECTGEOMETRY

This thread was mentioned in a similar discussion, so sharing my reply here in kind. If you can compile .NET, use @Danielm103's code - if you instead use Visual LISP, this may help:

Indoor or Outdoor? Nothing magical for AutoCAD that I know of. Just use general drafting techniques with what regulations you have, some equipment manufacturers have part models, though they could be only for Revit/BIM. Outdoor not much really to do but check regulations for berm heights, structures, shooting benches, any target supports, permanent targets, etc. The rest is just drafting. Indoor you need bulletproof roof, floors and walls (usually concrete), ventilation, acoustics/soundproofing, bullet traps (should be able to get model/drawing/specs from manufacturer), lighting considerations. Something like AutoCAD MEP and Architecture toolsets might be more useful. You might also want some video monitoring, a moveable target system for indoor might be wanted. Each part of the world and particular locations probably have different requirements, so probably no magic button.

As I posted in the other similar thread, I have found for most cases both FLATTEN and FLATSHOT of very little use. Posted somewhere on here are some TOOLBAR MACROs, which IMO does a better job for not too complex drawings to simply get a lot of basic objects to Z=0, as well as LISPs using the same method of moving everything then moving them all back. Initially it was needed for LT, not sure if something better can be used for newer LT with LISP. I'll repost the other thread which gives more on FLATTEN more complicated objects.
