I have a proposition for adding two new options in the command line when the “Planar sections” option is being activated from the pop-up window of the “Blend surface” command.
The first option called “Normal to surface” will let the modeler use a vector direction normal to a surface. This normal vector could be pointed with the mouse anywhere on the target surface in the same fashion as the ! _Line _Normal command.
The second option called “Normal between two surfaces” will do a similar job, except that it will take into account the intermediate vector that’s in-between two manually picked normal vectors on two target surfaces. I captured a video showing the general idea behind the 2nd option.
It would be nice if the vector for the “Planar sections” direction could be further modified, by showing rotational handles around its tip afterwards. The preview of the blend surface that uses a “Planar sections” vector then should update accordingly.
