Slm, friends; In an architectural project that came to me, one of the axis was drawn like a z-type, as you can see in the picture, I cannot define this axis as a drawing, nor can I define it with the 2D architectural project arrow command. How can I enter such an axis system? I also want to ask a question of appearance, which I have seen in many image attachments, for which I gave an example by quoting from the forum; How can we activate the view of the axles in the perspective view? Axes are not visible in my perspective images, besides, under my drawing area, materials, d.points, elements etc. How can I make the information screens visible? For example, in the picture below, I noticed that there are both submenus (elements, materials, points, etc.) and there are axes in the perspective view.
