I have been working a lot with Rhino in 2D to create technical drawings. It seems to me that when I create a fillet it asks for a radius. When I enter the radius - 3mm for example, it creates a fillet. When I use Radial Dimension to annotate the fillet it reads it as R1.5mm. This could be that the fillet tool is asking for a radius but in fact building a fillet using the input as a diameter.?? Please can you check this for me?
