Tangent Arc of Fixed Size
By default, Tangent to Entities creates a circle that touches three objects, and the arc is cut from this circle.
\1. To fix the size of the circle, enter the radius, diameter, or circumference in the Inspector Bar and lock it, but do not press Enter. When you move the cursor, the circle size remains constant.
\2. Select the second tangent object, close to the point of tangency.
\3. The fixed-sized tangent circle is created.
