Hi, can anyone please advise me how can I put a circle in the sketch for the exact place? For example, I have a square measuring 100x100mm and I need to put a circle with a diameter of 10 mm in the lower right corner (from the clip side 15mm and from the right side 23mm). I currently use Fusion, but I like this software Shapr3D much more.

You essentially have it correct already! There are many ways, but do as you have shown. You can use the offset tool to select a line, then move it over the distance you want. Then again the other direction. You’ll have an intersection of the two lines. Now use the circle tool and draw your circle using the intersection as the center.
