Good day. You already have a great tool for drawing.
However, you have poorly implemented binding to the sizes, drawing sections, diameters, and other tools needed to create professional tools. which would meet international standards.
I’ve been looking for free programs for drawing for a long time. Some programs allowed to make drawings with high accuracy, but they did not allow to make dimensions to the drawing, others - clearly made the design of the sizes, but it was not convenient to draw.
I ask you to. Make a tool for creating high-level drawings from your product.
