Dolgozunk most egy automatikus tervezőrendszeren az AI -jal. A ház 3D modellje alapján megvannak már a szükséges tervek: alaprajz, homlokzatok, metszetek. A tervező modul ezeket a terveket blokk -ként exportálja a cadR -be, ahol a további feldolgozás fog majd elkészülni: kottázás, egyéb feliratozás, rajzkeret hozzáadása, megjegyzés szövegek, stb.
Az első lépés a kottázás. Az alap elképzelés az, hogy van egy kijelölt objektum, és kezdeményezek egy Dimension utasítást. Ezután a program automatikusan felteszi az összes kottát egy lépésben. Mutatom a promptomat:
"Az alaprajzzal kezdjük. Ez egy viszonylag kis méretű blokk, amelyen belül nem nagyon érdemes kottázni. 2-3 külső kottasor fog kelleni mind a négy oldakon. A legkülső kotta a teljes méretet mutatja, az egyel beljebb lévő, az épület negyedében lévő falak távolságát és méretét mutatja, a még beljebb lévő, az ott lévő falakat kottázza."
Az első fotó a kottázás előtti állapot, a második a kottázott. Maga a kottázási művelet mérhetetlenül rövid idő alatt elkészül. A képek alapján is gondolom lehet látni, hogy lesz még néhány promptom, mire az a megoldás elfogadható szintre jut.

A C # program is relatively easy to reverse engineer, so the license management part needs to be protected. Obfuscation is usually used for this. This messes up the binary code of the EXE file, making it quite difficult to reverse engineer.
I searched the internet for my options and it turned out that I had quite a few solutions to choose from. The paid ones cost around $100 per month, so they are immediately out of stock, but there are also quite a few free ones. I spent about a day trying out the free ones and to my surprise, I didn't find a single one that worked.
No problem, I'll make one myself. I tried it with the usual AI support and it turned out that the program library commonly used for processing might be faulty, because none of our solutions worked.
That's when the idea came to me: wouldn't it be easier to make the source code unhackable? According to my loyal AI companion, this is a known solution and it's called SourceToSource Obfuscation. It didn't bother me that this had already been tried before, so we immediately threw ourselves into developing a solution.
This was the first obfuscated source code that I produced, so I inserted it back into the test program, and it refused to compile with an error message of 112. It took us about an hour to compile it without errors. Now came the test run of the resulting EXE. "Cannot find license manager" and it quits immediately. I don't want to increase the excitement, so after another half hour of bug hunting, I managed to run the program normally.
If I had to estimate how long it would have taken me to solve this without AI, I would guess at least 2 weeks.

Today we created different versions of the Dimension command. This was solved in AutoCAD with quite a few icons, which is understandable, because at the time the more buttons a program had, the more serious it seemed. We would like to cover this with one command. We have Dimension and that's it. Continue, Radius, Diameter have been successfully created, so that for example in the case of Continue, if the user clicks on an existing dimension line, the program switches to Continue mode. If you click on a circle, the program switches to Radius and if the next click is on the same circle, then to Diameter. When we were done with this, Copilot offered to continue with AngleDimension , but I have no idea how to bring it to life with the simple Dim command. I will have to come back to this later. I still have serious plans regarding Dimension . For example, the floor plan or the machine part is ready. The user selects the whole thing and sends Dim . In this case, the function analyzes the selected objects and completes the complete dimensioning work in one step. Of course, some AI help will be needed for this.

I talked to a dear friend about the cadR concept, and according to him, an AutoCAD clone will be successful if it is 100% identical to the original. I agree with this, since it is convenient for users with existing experience to be welcomed by the familiar program. During our conversation, however, I did not give up on the idea that instead of the original printing solutions, I should release a much easier-to-use one. On the other hand, I also noted that during the development I had to realize how efficient and usable the original software is.

All my appreciation to my predecessors!

In recent days, we have been working on print management. Instead of copying AutoCAD's print solutiont, we have come up with a different way of operating. The essence of this is that we use a PrintFrame object, which is a virtual print frame. It can be of different sizes: A5, A4, A3 (currently). If the need for other drawing sheet sizes arises later, we will expand the options with them. The PrintFrame can be placed on the Model sheet or on the Layout sheets. There can be any number of PrintFrames on each sheet. In the popup menu that appears when you right-click on PrintFrame , you can start PrintPreview , which appears as a new sheet after the Layouts . You can also start printing from the same place, so that the program displays the standard printer dialog so that printing starts on the appropriate printer. The File/Publish menu item prints all PrintFrames one after the other. In the case of PDF printing, this produces a multi-page document.

There are a few things that might be important for those who are not familiar with CAD system. Now the function keys came to mind:
F1 - context sensitive help (a lot is still missing, but it usually works)
F2 - result history (e.g. for distance measurement)
F3 - object snap (snap to endpoints, center points, etc.)
F8 - ortho (horizontal and vertical constraints)
I have never used the other function keys, but they will be built in, since we are not the same

CadR is being developed at full speed. In line with today's trends, I don't touch the code. The artificial intelligence is there to work for me. The program will have a FREE and a PRO version. Both work the same way. The difference is that the free version only handles JSON files, while the paid version only handles DWG/DXF files. The development is not yet complete. A lot of things are still at the proof-of-concept level. So there's still a lot to tinker with.
