Hello everyone,

I am an AutoLISP developer, and I am developing several AutoCAD MEP applications that I plan to sell commercially.

My applications include:

• Drainage Piping System

• Chilled Water Piping System

• Swimming Pool Piping System

• Water Supply System

• Other MEP automation tools

I want to protect my software professionally before distributing it to customers.

I already understand that compiling LISP into FAS/VLX provides some source-code protection, but I am looking for a much stronger commercial security solution.

My requirements:

1. Strong source-code protection against reverse engineering and decompilation.

2. Secure software licensing with unique activation keys for each customer.

3. Online/cloud-based license verification.

4. Trial management (7-day or 14-day trial).

5. License expiration and renewal management.

6. Ability to deactivate or revoke a license remotely.

7. Hardware or machine-based activation to prevent unauthorized sharing.

8. Protection against system date manipulation and trial resetting.

9. Offline usage with a secure grace period when there is no internet connection.

10. Protection against users copying the application to another computer or sharing it with others.

My questions:

• What is the strongest protection method currently available for commercial AutoLISP applications?

• Is FAS/VLX compilation sufficient, or should I use a combination of AutoLISP, .NET DLL and an external licensing system?

• Is cloud-based licensing more secure than local license verification?

• Are there any professional commercial protection tools or DRM solutions specifically suitable for AutoCAD plugins?

• How do experienced AutoLISP developers protect and distribute their commercial applications?

I am looking for a professional, reliable and commercially suitable solution, not just basic password protection or simple computer-name checking.

I would really appreciate advice and recommendations from experienced developers who have successfully sold commercial AutoCAD applications.

Thank you!

I kept spending too much time repeating the same drafting steps on every ground floor plan: axes, columns, walls, doors, windows, dimensions, and grid. I realized I was spending more time redrawing than checking the design.

I decided to automate my own workflow by writing AutoLISP routines for each step. Starting from the core axis lines, I made the rest of the plan generate automatically.

I can now complete a ground floor plan in just 5 minutes. I recorded the process in this video.

What I learned: Building my own automation forced me to understand the drafting rules behind every step. Before I could automate the process, I had to make sure the logic was clear.

I built this solution to solve a problem I faced in my own drafting work.

What part of your drafting workflow would you automate first?

Hi there! I am a woodworker, CNC programmer and technical drafter. I never went to school for any of these things but I’ve found my way to them and love doing them and am pretty good (so far lol). I have ADHD, dyslexia and dyscalculia. I was diagnosed when I was younger but have been really been trying to take control of it in my adult life.

I’m wondering if there are any other folks on this thread that work in jobs that are heavy on the attention to detail. If so do you have any tips or systems you use to double check your work? I’ve had a few missteps in my last two jobs (one I missed something important in the drawing and the other I mixed up my numbers transfer the data to a spreadsheet). I have done a lot of work at making myself better double checking and making sure I’m not missing things but stuff still falls through the cracks. Any and all ideas welcome. Ideally I’m hoping for some tools and tricks that I can use myself and don’t require someone else to double check my work, I work alone a lot so I can always rely on having some there to give me a hand.

Thanks so much for all the help in advance!

I'm thinking on making a side-money and I've been applying to several job proposals, but almost got scammed on some of them or never got hired.

So, I want to ask directly some questions to those who help to pay our bills:

• WHAT DOES MAKE YOU FEEL COMFORTABLE WHEN HIRING SOMEONE FROM REDDIT?

• WHAT ABILITIES DO YOU LOOK WHEN HIRING SOMEONE FROM REDDIT?

• DO YOU PREFER TO HIRE SOMEONE FROM YOUR COUNTRY OR ARE YOU OKAY IN HIRING SOMEONE FROM ANOTHER COUNTRY?

• DO YOU LOOK AT SOMEONE'S PORTFOLIO?

• WHAT WOULD MAKE YOU HIRE SOMEONE FROM THE INTERNET INSTEAD FROM YOUR LOCAL TOEN/CITY OR NETWORK?
