Of those technologies that we know, there is a softening and changing the properties of various materials, from marble to granite. Drilling, polishing, processing and creating perfect geometric shapes, all in the same granite.
Also, in some unknown way for us, in the past, they moved one hundred and even thousand-ton blocks, and they were also processed competently. And also other technologies that are no worse than ours and, as a rule, are associated with stones and their processing. But now to the copying technology, which could very well be in the past.
Megalith from Yanshan quarry, China, approximate weight - 16,250 tons.
How did you make the perfect polygonal masonry, like in Sacsayhuaman? Some concrete and similar versions are immediately nonsense, but there are many supporters of such versions.
If you ask yourself how to create such a perfect wall with such a fit of the blocks that there is often not even a millimeter gap between them. The answer is complicated, but most likely, you need to at least create a layout and calculate everything to the smallest detail and with minimal errors.
After that, you need to somehow create and process such stones and install all this. It all sounds very complicated, even if we imagine that the civilization of the past was superior to us in technology.

But what if no one handled anything by hand, machines and similar equipment were not needed, but there simply existed something like our modern 3D printer, only several times more?
And then we move to Egypt, where you can clearly see the technology of mirror blocks and exact copying. I doubt that the same blocks can be made manually, and it was hardly necessary.
One and the same structure and part of the blocks can be seen both on one side and on the opposite, as if someone was assembling a designer from the same mirror parts.
And after all, blocks in megalithic cities and complexes often have the same size. Immediately we think what good builders of the past made the same blocks, but it is likely that they were not processed, but simply copied or created on something similar, like a 3D printer.
Of course, one cannot confidently declare the existence of such a technology in the past, after all, there is not very much evidence, but it is there. And looking at the general picture of the possibilities of an unknown civilization of the past, they could have many technologies and even copy and create blocks using programs.
Whether or not to believe in such opportunities and technologies of the past, everyone decides for himself. However, I was convinced many times that the civilization of the past surpassed us in development and had perfect technologies.
