In my opinion, that option should be included in the tool (as a Command line option maybe?), because trying to guess the approximate value takes time and sometimes more than 3-5 attempts until a proper number could be found.
4 months ago, in another thread, I also made some suggestions for improvement of the newly implemented menu windows consisting the “Radius”, “Tangent” and “Bulge” sliders. I will post these here, as well. I find the current implementation of the sliders very limiting compared to the suggestions you see in this image. The inability to click on the slider and the min and max numbers to type a numerical value there is a huge disadvantage. Rhino’s interface must be more direct.
I also have an example that clearly shows some limitations of the new FilletSrfCrv tool. It’s unable to build a surface up to the right side edge of the target surface, reaching only the top of the circle.
